PASSAGE II

SOCIAL SCIENCE: This passage is adapted from the essay The Pedaled Revolution: How the Bicycle Shaped Modernity.

The 1890s are often remembered for the Gilded Age, the rise of industrial tycoons, and the expansion of the American railroad. Yet, on a more personal level, the decade was defined by a quieter, human-powered revolution: the bicycle boom. Prior to the late 1880s, cycling was a hazardous hobby reserved for daring young men. The standard machine of the era was the "penny-farthing," a precarious contraption featuring a massive front wheel and a tiny rear wheel, making it notoriously difficult to balance and dangerous to fall from.

The introduction of the "safety bicycle" in 1885 changed everything. Featuring two wheels of equal size, a chain drive, and pneumatic rubber tires, the safety bicycle was accessible, comfortable, and, most importantly, easy to ride. Almost overnight, cycling transformed from an extreme sport into a mass phenomenon. By 1897, over two million bicycles were being sold annually in the United States alone.

This explosion in popularity had immediate economic ripple effects. The demand for bicycles drove innovations in manufacturing, specifically in the production of ball bearings, steel tubing, and stamped metal parts. Moreover, the millions of new cyclists quickly realized that America's infrastructure was woefully inadequate for their new machines. Outside of major city centers, most roads were little more than dirt paths, prone to turning into impassable muddy ruts after a rainstorm. In response, cyclists formed the League of American Wheelmen, a powerful lobbying group that launched the "Good Roads Movement." They successfully pressured local and state governments to pave roads and improve streetscapes, laying the literal groundwork for the automobile era that was soon to follow.

However, the bicycle's most profound impact was arguably sociological, particularly regarding the lives of women. In the late nineteenth century, Victorian social codes strictly dictated female behavior and dress. Women were expected to wear heavy, restrictive corsets and long, voluminous skirts that swept the ground, outfits that made physical exertion nearly impossible. The safety bicycle demanded a different wardrobe.

To ride comfortably and safely, women began adopting "rational dress," which included divided skirts, shorter hemlines, and most controversially, bloomers. While conservative critics decried these fashion changes as scandalous, the bicycle offered women an unprecedented degree of physical mobility and independence. They no longer had to rely on men to drive carriages or wait for scheduled trains; a woman with a bicycle could travel miles under her own power. In 1896, women's rights leader Susan B. Anthony famously declared, "I think (the bicycle) has done more to emancipate women than anything else in the world. It gives a woman a feeling of freedom and self-reliance."

The bicycle also acted as a social leveler in rural communities. Farm life in the 1800s was often deeply isolating. The horse-and-buggy was expensive to maintain and slow, limiting the radius of a typical farmer's social circle to just a few miles. The bicycle collapsed these distances. Young adults could easily pedal to neighboring towns for dances, church socials, and political meetings. Sociologists note that the advent of the bicycle significantly broadened the marriage pool in rural areas, as people were suddenly able to court partners who lived outside their immediate geographic confines.

Ultimately, the bicycle craze of the 1890s was brief, eclipsed within a few decades by the advent of the affordable automobile. Yet, the social and physical landscape of America had been irreversibly altered. The bicycle had paved the roads, modernized manufacturing, and given marginalized groups a taste of autonomous travel. It was a simple machine that accelerated the arrival of the modern world.

The author includes the quote from Susan B. Anthony primarily to:

1 When I turned into the gravel drive that led 2 to my grandfather's orchard, the pear trees stood in 3 rows exactly as I remembered them, though smaller now, 4 as if the years between had shrunk the whole 5 property down to the size of a photograph I 6 once kept folded in a coat pocket. I had 7 not come back out of nostalgia. The county assessor's 8 letter, addressed to me as the sole surviving heir, 9 demanded a decision by the end of the month: 10 sell the thirty acres to the development firm that 11 had already leveled the Hoffman farm two miles east, 12 or find some way to keep the orchard solvent 13 on my own.

14 My grandfather had never once, in the 15 forty years I knew him, spoken of the orchard 16 as a burden. He rose before dawn to walk 17 the rows with a lantern, checking for blight, and 18 he could tell you, tree by tree, which limbs 19 had been grafted and which had grown wild from 20 seed. I used to think his devotion was a 21 kind of stubbornness, a refusal to admit that a 22 man could love land more than it could ever 23 love him back. It took me most of my 24 adult life, and several failed attempts at other work, 25 to understand that he was not stubborn at all. 26 He simply measured a good year by different arithmetic 27 than the one I had learned in business school.

28 The development firm's representative met me at the gate 29 on a Tuesday, carrying a folder of comparables and 30 a manner so gently apologetic that I nearly forgot 31 he was offering to erase thirty acres of pear 32 trees for a subdivision of identical brick houses. He 33 spoke of appreciation rates and school district boundaries. I 34 found myself, instead of listening, counting the trees I 35 could see from where we stood, the way my 36 grandfather once counted them, as though a number could 37 hold a place together. When he finished, I told 38 him I needed another week, which was less a 39 negotiating tactic than an admission that I did not 40 yet know my own mind.

41 That evening I walked the rows alone, the way 42 I had not done since the funeral, and found 43 that I still knew which limbs had been grafted. 44 My hands remembered before my memory did, reaching for 45 a low branch on the Bartlett tree the way 46 they had reached for it as a boy testing 47 fruit for ripeness. I did not decide anything that 48 night. But I noticed that I was no longer 49 thinking in the assessor's arithmetic, the arithmetic of comparables 50 and appreciation rates, and had slipped instead into my 51 grandfather's, the arithmetic of blight checked and limbs grafted 52 and a good year measured by the weight of 53 fruit a single tree could bear.

54 I do not know yet what I will tell 55 the development firm's representative when the week is up. 56 I know only that the orchard has begun to 57 ask a question of me that no letter from 58 the county assessor ever thought to ask, and that 59 the question has less to do with land values 60 than with whether I am willing to learn, at 61 thirty-four, an arithmetic I spent my whole life trying 62 to leave behind.

The fourth paragraph (lines 41-53) primarily serves to:

1 Every June, for about two weeks, a stretch of 2 forest in the southern Appalachians goes dark in a 3 peculiar way: thousands of male fireflies flash in near 4 unison, a pulse of green light rolling through the 5 understory like a slow tide, followed by several seconds 6 of total darkness before the next pulse begins. Photinus 7 carolinus is one of only a handful of firefly 8 species worldwide known to synchronize its flashing, and for 9 decades the phenomenon was documented almost entirely by professional 10 entomologists willing to spend weeks camping beside the same 11 ridge, counting pulses by hand and comparing notes by 12 flashlight.

13 That has changed. Over the past fifteen years, a 14 volunteer monitoring program has trained thousands of visitors to 15 record flash intervals on a standardized form, noting the 16 date, the temperature, and the number of seconds between 17 pulses at a given location. The resulting data set 18 now spans far more nights, and far more square 19 miles of forest, than any team of professional researchers 20 could have covered alone, and it has already revealed 21 that synchrony breaks down earlier in warmer years than 22 researchers had previously assumed, a pattern that would have 23 taken a small research team the better part of 24 a decade to document with statistical confidence.

25 Some entomologists remain uneasy about leaning on this kind 26 of data. A volunteer counting flashes after a full 27 day of hiking, in failing light, without formal training 28 in insect behavior, will occasionally misjudge an interval or 29 mistake a distant flashlight for a firefly pulse, and 30 these errors do not average out as neatly as 31 program organizers sometimes suggest, since a single overeager volunteer 32 can submit dozens of entries in one evening, weighting 33 the data set toward that person's particular habits of 34 observation. The organizers have answered this concern with cross-checking 35 protocols, comparing volunteer counts against a smaller set of 36 simultaneous professional recordings, and the two data sets have 37 tracked closely enough to reassure most skeptics, though not 38 all of them.

39 I raise this tension not to settle it but 40 because it clarifies something important about what citizen science 41 is actually for. It is not a cheap substitute 42 for professional fieldwork, a way of getting the same 43 answers for less money, and treating it that way 44 invites exactly the sloppiness that skeptical entomologists fear. Its 45 real value lies in a different register entirely: it 46 can ask questions that professional fieldwork, constrained by grant 47 cycles and small research teams, was never going to 48 answer on its own, because those questions require the 49 kind of geographic and temporal coverage that only thousands 50 of ordinary evenings, contributed by thousands of ordinary people, 51 can provide.

52 What the firefly data ultimately shows is not that 53 amateurs can do a professional's job as well as 54 a professional. It is that some scientific questions were 55 never within a professional's reach in the first place, 56 and that the choice is not between rigorous data 57 and generous data, but between a narrow data set 58 collected with total control and a vast one collected 59 with careful, if imperfect, oversight. For a species whose 60 entire behavior depends on the collective timing of thousands 61 of individual insects, it seems fitting that understanding it 62 should likewise depend on the collective, imperfect attention of 63 thousands of individual observers.

The author's discussion of entomologists' unease about volunteer data (lines 25-38) primarily functions to:

1 Every June, for about two weeks, a stretch of 2 forest in the southern Appalachians goes dark in a 3 peculiar way: thousands of male fireflies flash in near 4 unison, a pulse of green light rolling through the 5 understory like a slow tide, followed by several seconds 6 of total darkness before the next pulse begins.

The main purpose of the passage is to:

1 On a single foggy night in October of 1954, 2 nearly fifty thousand migrating birds died after striking the 3 beacon atop a television tower in Georgia. The birds 4 had not lost their way by accident; they had 5 been drawn, moth-like, toward a light source that 6 interrupted the celestial and magnetic cues they use to 7 navigate thousands of miles between breeding grounds and wintering 8 territory. Ornithologists who studied the wreckage the next morning 9 described drifts of warblers and thrushes piled against the 10 tower's guy wires, as though the birds had simply 11 run out of sky. That single incident, horrifying as 12 it was, turned out to be neither new nor rare.

13 Most migratory songbirds travel at night, relying on a 14 combination of star patterns and an internal magnetic sense 15 to hold a steady course across continents. Artificial light, 16 however, appears to override both systems at once. Birds 17 entering a lit airspace do not merely notice the 18 glow and steer around it; they become, in the 19 words of one researcher, "trapped in a bubble of 20 brightness," circling a building or tower for hours until 21 exhaustion or collision ends the flight. The behavior is 22 not a failure of intelligence so much as a 23 mismatch between an ancient navigational system and a wholly 24 modern hazard that birds have had no evolutionary time to answer.

25 The phenomenon, though amplified by modern glass towers, is 26 not itself modern. Nineteenth-century lighthouse keepers along the 27 Atlantic coast kept logbooks noting nights when, as one 28 keeper wrote in 1882, "the air was thick with 29 birds beating against the lantern room glass until dawn." 30 Keepers on the Farallon Islands and along the Carolina 31 capes recorded similar scenes decades apart, often describing thousands 32 of birds circling a single beam until the fog 33 lifted or the light was doused. These accounts, gathered 34 long before anyone understood magnetic navigation, show that the 35 vulnerability is not a defect introduced by contemporary architecture 36 but a susceptibility built into the birds' own guidance system.

37 Today's hazard is simply the nineteenth century's problem multiplied. 38 A single illuminated skyscraper can kill more birds in 39 one night than a lighthouse ever could, both because 40 cities burn far brighter than any lamp a keeper 41 once tended and because glass facades, reflecting sky and 42 cloud, confuse birds even in daylight. Chicago's McCormick Place, 43 a convention center studied for over four decades, has 44 recorded tens of thousands of collision deaths, with mortality 45 spiking on nights when floor-to-ceiling windows stay lit 46 and migration traffic overhead is heaviest. Researchers now treat 47 such buildings as case studies in exactly the disorientation 48 that lighthouse keepers described in prose a century earlier.

49 None of this means glass and electricity are the 50 enemy of migration; it means the response has to 51 match the age of the vulnerability. Cities that have 52 adopted lights-out programs, dimming nonessential lighting during peak 53 migration weeks, report measurable drops in collision deaths within 54 a single season. The lighthouse keepers could not have 55 dimmed their beacons without risking ships on the rocks; 56 builders of glass towers have no comparable excuse. If 57 a hazard this old can still be solved with 58 something as simple as a light switch, the failure 59 to act becomes a choice, not an accident of technology.

The author includes the detail about nineteenth-century lighthouse keepers' logbooks (lines 25-36) primarily to:

1 When I was eleven, my mother enrolled me in 2 piano lessons with Mrs. Abernathy, a woman whose parlor 3 always smelled faintly of camphor and old sheet music 4 left too long in drawers. I hated the lessons 5 at first. I resented the metronome's clicking insistence, and 6 I dreaded the fifteen-minute drive past the limestone quarry 7 to reach her house. But by the third month, 8 something had shifted. I had stopped counting the minutes 9 until the lesson ended and started counting the measures 10 until I reached the passage I actually wanted to play.

11 Mrs. Abernathy never praised me the way other adults 12 praised children in that decade, with the easy currency 13 of "good job" handed out for simply showing up. 14 She listened to a scale I had practiced for 15 a week, said nothing for a long moment, and 16 then told me precisely where my wrist had tightened. 17 I did not understand, then, that this withholding was 18 itself a form of attention rarer than praise. I 19 only knew that when she finally said "yes, that," 20 I felt something close to vindication.

21 I think now that I write about her not 22 because she made me a musician — I was never 23 more than competent — but because she taught me 24 what it felt like to be taken seriously by 25 an adult who owed me nothing. My parents' attention 26 was a given, woven into the obligations of raising 27 me. Hers was earned, lesson by lesson, and its 28 scarcity was the whole of its value. I did 29 not know how rare that particular feeling would turn 30 out to be until decades later, when I found 31 myself searching for it in editors, in employers, in 32 strangers at dinner parties, and rarely finding it.

33 She died the winter I turned thirty, and I 34 did not go to the funeral. I told myself 35 I was too far away, too busy, and both 36 of those things were technically true. What was also 37 true, though harder to admit, was that I did 38 not want to sit in a room with people 39 who had known her only as a fixture of 40 the town and not as the person who had, 41 without ever saying so directly, convinced an anxious eleven-year-old 42 that discipline and love were not opposites. I wanted 43 to keep that version of her private, unshared, undiluted 44 by the ordinary grief of strangers.

45 I am fifty-two now, and I no longer play. 46 My hands have grown stiff, and the piano in 47 my living room is mostly a shelf for photographs. 48 But I still hear her voice sometimes when I 49 catch myself doing something halfway — my wrist tightening, my 50 attention drifting toward the door instead of the work 51 in front of me — and I straighten, almost involuntarily, 52 the way I did in that camphor-scented parlor forty 53 years ago. That, I have come to believe, is 54 the only kind of immortality a good teacher actually 55 gets: not a monument, not a mention in an 56 obituary, but a posture someone else's hands still remember.

The author includes the detail about searching "in editors, in employers, in strangers at dinner parties" (lines 31-32) primarily to:

1 When restorers finished cleaning the ceiling frescoes in the 2 old chapel last spring, unveiling colors no one alive 3 had ever seen — a cobalt sky instead of the 4 soot-brown haze generations had mistaken for the artist's original 5 intent — the response split cleanly along a fault line 6 that has run through art conservation for a century. 7 One camp welcomed the transformation as an overdue correction, 8 arguing that five hundred years of candle smoke and 9 varnish had slowly murdered the painting and that removing 10 them was simply giving the artist back his own 11 colors. The other camp recoiled, insisting that the muted 12 palette the restorers scrubbed away had itself become part 13 of the work's meaning, inseparable from how it had 14 been experienced, discussed, and painted-over by every generation since.

15 I confess I arrived at the unveiling already suspicious 16 of restoration, having watched too many older cleanings turn 17 brittle and yellow within a decade, proving that the 18 previous generation's "correction" was simply a new layer of 19 decay waiting to happen. But standing beneath the actual 20 ceiling, I found the cobalt sky harder to dismiss 21 than I expected. The figures, freed of centuries of 22 grime, suddenly had a spatial logic that the darkened 23 version had flattened into murk; a hand that had 24 seemed to rest limply on a knee turned out, 25 in clean light, to be gesturing toward a figure 26 across the room. That gesture had simply been invisible 27 for three hundred years. No theory of preserving accumulated 28 meaning, however sophisticated, restores information that soot has erased.

29 And yet the theory is not merely sophisticated; it 30 is not wrong, either. A fresco is not only 31 a set of pigments applied by one artist in 32 one decade. It is also an object that later 33 centuries received, misread, argued over, and altered — sometimes through 34 vandalism, more often through the well-meaning touch-ups of restorers 35 now three or four cleanings in the past. To 36 scrub a work back to a hypothetical original state 37 is to make a choice about which of its 38 many lives counts as the real one, and that 39 choice is never as neutral as the word "cleaning" 40 makes it sound. The chapel's cobalt sky is not 41 the fresco Michelangelo's contemporaries saw either; it is the 42 fresco as current restoration science believes it once looked, 43 filtered through instruments and judgment calls no fifteenth-century viewer 44 could have imagined.

45 I do not think this makes the cleaning a 46 mistake. I think it means we should stop talking 47 about restoration as though it simply reveals a hidden 48 truth, and start talking about it as what it 49 actually is: an interpretation, executed in solvent instead of 50 prose, that happens to be far harder to argue 51 with once it has physically removed the alternative.

The description of the hand's gesture becoming visible after cleaning (lines 21-27) primarily functions to:

1 For most of the twentieth century, biologists treated color-changing 2 skin in cephalopods as a fairly simple trick: chromatophores, 3 tiny sacs of pigment embedded in the skin, expand 4 or contract under neural control, and the animal's outline 5 blurs into its surroundings. The story had the tidy 6 shape of a textbook diagram, and for decades almost 7 no one bothered to ask a more uncomfortable question, 8 namely how an animal that is, by every anatomical 9 measure, colorblind manages to match not just the brightness 10 but the actual hue of a coral reef or 11 a mottled rock.

12 The chromatophore story is not wrong, exactly, but it 13 is radically incomplete. Recent work on octopus skin has 14 identified light-sensitive proteins called opsins scattered directly in the 15 skin tissue itself, far from the animal's eyes, that 16 appear to let the skin respond to the color 17 and intensity of ambient light without any signal traveling 18 through the optic nerve at all. Some researchers now 19 suspect the skin is doing something closer to seeing 20 than to simply displaying, a possibility that unsettles the 21 tidy division most biology students learn between the organs 22 that gather information and the organs that merely display it.

23 None of this proves that an octopus's skin "sees" 24 in any sense a human would recognize as vision; 25 no image, no scene, nothing resembling a picture appears 26 to be assembled anywhere in the skin's distributed network 27 of light-sensitive cells. What the evidence does support is 28 a more modest but still startling claim: that camouflage 29 in these animals may not be a one-way broadcast, 30 commanded top-down by a brain that has already looked 31 around and decided on a disguise, but something closer 32 to a conversation between skin and light that never 33 fully reports back to the brain that supposedly runs 34 the show.

35 That distinction matters for reasons beyond cephalopod trivia. Neuroscientists 36 have spent a century assuming that behavior this coordinated 37 must be centrally directed, that some executive structure has 38 to be gathering sensory data and issuing the corresponding 39 motor commands. The octopus, with a nervous system in 40 which roughly two-thirds of its neurons sit not in 41 its brain but distributed through its arms and skin, 42 has never fit that assumption comfortably, and the discovery 43 of skin-based light sensitivity is one more piece of 44 evidence that the animal's intelligence, whatever we end up 45 calling it, may be less a single throne than 46 a loose and surprisingly capable parliament.

47 For now, the practical upshot is narrower: aquarium lighting 48 rigs, once tuned mainly for visitor comfort, are being 49 reconsidered by researchers who suspect that the wrong ambient 50 spectrum may be quietly stressing animals whose skin, it 51 turns out, was never merely along for the ride.

The author's comparison of octopus intelligence to "a loose and surprisingly capable parliament" rather than "a single throne" (lines 45-46) primarily serves to:

1 The traveler had knocked twice before anyone answered, and 2 when the door finally opened, an old man in 3 a leather apron stood blinking against the porch light. 4 "You're the one with the broken trunk," he said, 5 not as a question but as a fact he had 6 already settled in his mind before she spoke a 7 word. Mara nodded, too tired to explain how her 8 car had stalled three miles back or how she 9 had walked the rest of the way carrying a 10 suitcase whose latch had snapped somewhere between the highway 11 and this unfamiliar town.

12 Mr. Okafor did not ask why a woman traveled 13 alone at midnight with a broken suitcase, and he 14 did not comment on the mud caking her shoes. 15 He simply set the case on his workbench, switched 16 on a lamp shaped like a lantern, and began 17 sorting through drawers of pins and springs with the 18 unhurried patience of someone who had spent forty years 19 coaxing stubborn mechanisms back into cooperation. Mara watched his 20 hands, thick-knuckled and scarred, move with a precision that 21 seemed almost tender, as though the latch were something 22 wounded rather than simply broken.

23 "People bring me their locks when everything else has 24 failed," he told her, without looking up from the 25 small brass mechanism now spread across a square of 26 velvet. "A jammed door, a stuck safe, a suitcase 27 that won't open on the one night you actually 28 need what's inside it. They come in frightened, and 29 they leave still frightened, usually, because I can't fix 30 the reason they needed the lock opened in the 31 first place. I can only fix the lock." Mara 32 said nothing, but she thought of the letter folded 33 inside that suitcase, the one she had been carrying 34 for six hundred miles without reading past its first 35 line.

36 When the latch finally gave way with a soft 37 click, Mr. Okafor did not open the lid himself. 38 He turned the suitcase toward her and stepped back, 39 the way a doctor might step back after setting 40 a bone, leaving the rest of the healing to 41 the patient. "That's yours to open," he said, "not 42 mine." Mara's fingers hovered over the latch for a 43 long moment before she lifted it, and the old 44 locksmith busied himself sweeping metal shavings from his workbench, 45 giving her the privacy of a stranger who understood that 46 some doors, once opened, cannot be closed again.

47 She never told him what was inside, and he 48 never asked. But years later, whenever a lock stuck 49 or a stubborn door refused to yield, she thought 50 of his velvet cloth, his patient hands, and the 51 quiet dignity of a man who mended what he 52 could and left what he couldn't to the person 53 who owned it.

Which choice best describes the function of the final paragraph (lines 47-53) in relation to the rest of the passage?

1 In the decades after the Civil War, a number 2 of American manufacturers built entire towns around their factories, 3 complete with company-owned housing, company-owned stores, and company-appointed 4 clergy. Historians have long debated whether these towns represented 5 genuine benevolence or a subtler form of control, and 6 the truth, as usual, resists a tidy answer. What 7 is clear is that the men who built Pullman, 8 Illinois, and Hershey, Pennsylvania, did not think of themselves 9 as tyrants. They thought of themselves as improvers, correcting 10 the squalor of industrial cities by offering workers clean 11 streets, indoor plumbing, and libraries their wages could never 12 have purchased on the open market.

13 Yet the very completeness of these towns is what 14 should give us pause. A worker in Pullman rented 15 his home from the company, bought his groceries from 16 the company, and sent his children to a school 17 staffed by the company. When wages fell during the 18 depression of 1893, rents did not fall with them, 19 because rents were set not by the housing market 20 but by the company's own accountants, who saw no 21 contradiction in demanding full rent from workers whose paychecks 22 they had just cut. The town, in other words, 23 had been designed so that dependence flowed in only 24 one direction. A resident could not simply move to 25 cheaper lodging across town, because there was no other 26 town; the company was the landlord, the employer, and, 27 in a very real sense, the government.

28 Defenders of the company town model point to genuine 29 improvements in worker health and literacy, and these gains 30 were real. Infant mortality in Pullman fell below the 31 rate in nearby Chicago, and the town's library circulated 32 more books per resident than many public systems of 33 the era. But it is worth asking what such 34 amenities cost the people who received them. Workers who 35 criticized company policy risked more than their jobs; they 36 risked their homes and their children's school enrollment in 37 a single dismissal notice. A strike in 1894 collapsed 38 in part because striking workers faced eviction from company 39 housing within weeks, a pressure no independent town could 40 have applied.

41 It would be too simple to call company towns 42 purely exploitative, since many residents genuinely preferred them to 43 the tenements of Chicago or Pittsburgh. But it would 44 be equally mistaken to treat the amenities as evidence 45 of pure generosity, divorced from calculation. The men who 46 designed these towns understood, whether they said so aloud 47 or not, that a contented worker who owed his 48 house, his groceries, and his children's schooling to one 49 employer was a worker unlikely to organize against that 50 employer. Comfort, in Pullman, was not opposed to control; 51 it was one of control's most effective instruments.

52 Reading the promotional pamphlets these companies distributed to prospective 53 workers, one notices how rarely the word "rent" appears 54 next to the word "control," and how often words 55 like "family" and "improvement" appear instead. The vocabulary of 56 paternalism, then as now, tends to describe dependency in 57 the language of care.

The author includes the detail about promotional pamphlets in the final paragraph (lines 52-57) primarily to:

1 When restorers speak of "cleaning" an old film, the 2 verb suggests something simple: wipe away the dirt, remove 3 the scratches, return the image to the condition it 4 had on its first night in a theater. In 5 practice, digital restoration is rarely so modest. Software can 6 now smooth grain, stabilize a trembling frame, sharpen a 7 blurred face, and correct a color that faded decades 8 ago into an unintended sepia. The temptation, once these 9 tools exist, is to use all of them, and 10 studios eager to sell a film to a new 11 generation of streaming subscribers often do exactly that.

12 I want to argue for restraint, and for a 13 distinction that restoration technicians sometimes forget: there is a 14 difference between damage and texture. A scratch that runs 15 through every reel of a film, caused by a 16 faulty projector decades ago, is damage, and removing it 17 restores the image to something closer to what the 18 director intended. But the grain of a film shot 19 on nitrate stock in 1947 is not damage. It 20 is the visible signature of the medium itself, the 21 chemical grain structure that gave mid-century black-and-white cinema its 22 particular weight and shadow. Scrub that grain away with 23 noise-reduction software, as several recent restorations have done, and 24 you do not reveal the film underneath; you erase 25 it and replace it with a smoother, flatter, more 26 digital-looking image that never existed on any reel anyone 27 actually projected.

28 Defenders of aggressive restoration argue that modern audiences, raised 29 on crisp digital images, cannot appreciate grain and simply 30 perceive it as a technical flaw, an obstacle between 31 them and the story. There is something to this; 32 a viewer unfamiliar with celluloid may indeed read grain 33 as a fault rather than a feature. But that 34 strikes me as an argument for education, not erasure. 35 We do not sand the brushstrokes off an oil 36 painting because a visitor mistakes texture for damage; we 37 explain the medium to the visitor. Film restoration should 38 aspire to the same humility.

39 The stakes here are not merely aesthetic. A restoration 40 that smooths away grain and stabilizes every tremor also 41 smooths away evidence, the kind film historians rely on 42 to date a print, trace which theater chain projected 43 it, or identify which of several surviving negatives a 44 given restoration derives from. Once that evidence is scrubbed 45 clean, in effect, from a digital master, later scholars 46 inherit an image that looks pristine and tells them 47 almost nothing about its own history.

48 None of this means restoration itself is misguided; a 49 brittle, decaying reel deserves rescue, and digital tools have 50 saved films that would otherwise have disintegrated entirely. The 51 question is not whether to restore but what, precisely, 52 we think we are restoring: the film as it 53 was screened, grain and flicker and all, or some 54 imagined ideal version that never actually existed on a 55 strip of nitrate.

1 For more than a century, biologists have known that 2 European eels vanish from the rivers of Europe each 3 autumn and reappear the following spring as transparent larvae 4 drifting on ocean currents, yet no scientist has ever 5 directly observed an adult eel spawning in the wild. 6 The gap between these two facts, one of the 7 oldest unsolved mysteries in marine biology, has produced a 8 century of ingenious but ultimately incomplete detective work.

9 In 1922, the Danish researcher Johannes Schmidt announced what 10 seemed to be the answer: after tracking eel larvae 11 of decreasing size across thousands of miles of Atlantic 12 Ocean, he concluded that European eels must spawn somewhere 13 within the Sargasso Sea, a vast, current-bounded region east 14 of Bermuda known for its calm waters and floating 15 mats of golden seaweed. Schmidt's conclusion, based on years 16 of painstaking net surveys rather than any direct sighting, 17 became the textbook answer, repeated in classrooms for the 18 next hundred years largely unchallenged.

19 Yet repetition is not confirmation, and the truth is 20 that Schmidt's evidence, however careful, was circumstantial. He never 21 saw an adult eel in the Sargasso Sea, spawning 22 or otherwise; he inferred the location from the sizes 23 of larvae collected at different points along their presumed 24 drift. It was, in effect, a crime scene reconstructed 25 entirely from the position of footprints, without ever locating 26 a suspect. Modern researchers, armed with satellite tags rather 27 than nets, have spent the past two decades trying 28 to close that gap, attaching tracking devices to adult 29 eels captured near European coasts and following their signals 30 as the eels swim thousands of miles toward the 31 presumed spawning grounds.

32 The tagging studies have confirmed much of Schmidt's reconstruction: 33 eels do travel toward the Sargasso Sea, and their 34 migratory routes match his predicted currents with striking accuracy. 35 But the tags themselves, designed to detach and float 36 to the surface after a set period, have almost 37 always popped free before the eels reach the presumed 38 spawning grounds, whether from mechanical failure, predation, or simple 39 battery limits. No tag has yet transmitted from directly 40 within the Sargasso Sea itself, which means the final, 41 most crucial leg of the journey remains exactly as 42 unwitnessed today as it was in Schmidt's era.

43 This persistent gap matters for reasons beyond scientific curiosity. 44 European eel populations have collapsed by more than ninety 45 percent since the 1980s, and conservation plans depend on 46 knowing precisely where and when spawning occurs, since protections 47 aimed at the wrong stretch of ocean, or the 48 wrong season, would do little to help a population 49 already in steep decline. Until a research vessel or 50 a luckier tag finally captures the missing final chapter, 51 the eel's most important act will remain, ironically, the 52 one biologists understand least.

The author's comparison of Schmidt's evidence to "a crime scene reconstructed entirely from the position of footprints" (lines 24-25) primarily serves to:

PASSAGE IV

NATURAL SCIENCE: This passage is adapted from the article Life in the Dark: The Oasis of the Abyss.

Until the late twentieth century, marine biologists operated under a fundamental assumption: all life on Earth ultimately depended on the sun. Photosynthesis was the undisputed engine of the global food web. It was believed that the deep ocean floor, plunged in perpetual darkness, freezing temperatures, and crushing pressure, was a biological desert. Scientists assumed that the few scavengers living in the abyss survived solely on "marine snow"—the slow drift of dead organic matter falling from the sunlit surface miles above.

That paradigm was shattered in 1977. Geologists piloting the deep-sea submersible Alvin were exploring the Galápagos Rift, a mid-ocean ridge in the eastern Pacific. They were searching for hydrothermal vents—underwater hot springs predicted by plate tectonic theory. They found the vents, but they also found something entirely unexpected: a thriving, densely populated ecosystem.

The vents are formed where the Earth's tectonic plates spread apart. Freezing seawater seeps down through cracks in the ocean crust and is heated by underlying magma chambers to temperatures exceeding 400°C (750°F). Because of the extreme hydrostatic pressure, the water does not boil. Instead, it becomes superheated and highly corrosive, leaching minerals like iron, copper, and zinc from the surrounding rocks. When this buoyant, mineral-rich fluid shoots back up into the freezing ocean water, the dissolved minerals instantly precipitate out, forming massive chimney-like structures known as "black smokers."

The sheer abundance of life around these toxic, boiling geysers was a biological anomaly. There were blind white crabs, pale eel-like fish, and beds of giant clams. Most striking were the giant tube worms, Riftia pachyptila, which grew up to eight feet long in dense, bush-like clusters, waving blood-red plumes in the dark water. Without sunlight, how was this oasis of life sustaining itself? The answer lay in a process entirely separate from photosynthesis: chemosynthesis.

The vent fluids are rich in hydrogen sulfide ($H_2S$), a chemical compound highly toxic to most known terrestrial and shallow-water organisms. However, specialized microorganisms—chemosynthetic bacteria—have evolved to use the chemical energy stored in the bonds of hydrogen sulfide to convert carbon dioxide and water into organic sugars. In this abyssal ecosystem, these bacteria serve the exact same foundational role that plants serve in a sunlit forest.

The giant tube worms are perhaps the most remarkable example of evolutionary adaptation to this environment. Upon dissection, biologists discovered that the adult Riftia tube worm has no mouth, no digestive tract, and no anus. It cannot eat in any traditional sense. Instead, its body contains a massive internal organ called a trophosome, which houses billions of symbiotic chemosynthetic bacteria. The worm's red plume acts as a gill, absorbing oxygen, carbon dioxide, and hydrogen sulfide from the water and transporting them via its blood to the bacteria. In return, the bacteria synthesize the organic compounds the worm needs to survive and grow at astonishingly rapid rates.

The discovery of hydrothermal vent communities fundamentally expanded our understanding of biology. It proved that life could thrive in the most extreme, hostile environments on the planet, completely divorced from solar energy. Furthermore, the genetic ancientness of these chemosynthetic bacteria has led some evolutionary biologists to propose a radical new theory: that life on Earth may not have begun in a warm, shallow sunlit tide pool, as Charles Darwin once speculated, but rather in the dark, boiling, chemical-rich crucible of a deep-sea vent.

The author's detailed description of the tube worm's anatomy — specifically its lack of a mouth, digestive tract, and anus — primarily serves to:

1 The traveler had knocked twice before anyone answered, and 2 when the door finally opened, an old man in 3 a leather apron stood blinking against the porch light. 4 "You're the one with the broken trunk," he said, 5 not as a question but as a fact he had 6 already settled in his mind before she spoke a 7 word. Mara nodded, too tired to explain how her 8 car had stalled three miles back or how she 9 had walked the rest of the way carrying a 10 suitcase whose latch had snapped somewhere between the highway 11 and this unfamiliar town.

12 Mr. Okafor did not ask why a woman traveled 13 alone at midnight with a broken suitcase, and he 14 did not comment on the mud caking her shoes. 15 He simply set the case on his workbench, switched 16 on a lamp shaped like a lantern, and began 17 sorting through drawers of pins and springs with the 18 unhurried patience of someone who had spent forty years 19 coaxing stubborn mechanisms back into cooperation. Mara watched his 20 hands, thick-knuckled and scarred, move with a precision that 21 seemed almost tender, as though the latch were something 22 wounded rather than simply broken.

23 "People bring me their locks when everything else has 24 failed," he told her, without looking up from the 25 small brass mechanism now spread across a square of 26 velvet. "A jammed door, a stuck safe, a suitcase 27 that won't open on the one night you actually 28 need what's inside it. They come in frightened, and 29 they leave still frightened, usually, because I can't fix 30 the reason they needed the lock opened in the 31 first place. I can only fix the lock." Mara 32 said nothing, but she thought of the letter folded 33 inside that suitcase, the one she had been carrying 34 for six hundred miles without reading past its first 35 line.

36 When the latch finally gave way with a soft 37 click, Mr. Okafor did not open the lid himself. 38 He turned the suitcase toward her and stepped back, 39 the way a doctor might step back after setting 40 a bone, leaving the rest of the healing to 41 the patient. "That's yours to open," he said, "not 42 mine." Mara's fingers hovered over the latch for a 43 long moment before she lifted it, and the old 44 locksmith busied himself sweeping metal shavings from his workbench, 45 giving her the privacy of a stranger who understood that 46 some doors, once opened, cannot be closed again.

47 She never told him what was inside, and he 48 never asked. But years later, whenever a lock stuck 49 or a stubborn door refused to yield, she thought 50 of his velvet cloth, his patient hands, and the 51 quiet dignity of a man who mended what he 52 could and left what he couldn't to the person 53 who owned it.

The author most likely includes Mr. Okafor's comment that he can only "fix the lock" (lines 29-31) primarily to:

1 Marine biologists have spent decades marveling at the octopus's 2 uncanny ability to vanish into its surroundings within a 3 fraction of a second, a trick performed not with 4 pigment alone but with a symphony of muscle, nerve, 5 and light-sensitive skin cells working in concert. The creature 6 has no cones or rods embedded in its arms, 7 yet it somehow reads the color and texture of 8 a nearby rock or frond of kelp and reproduces 9 that pattern across thousands of tiny sacs called chromatophores, 10 each one capable of expanding or contracting within milliseconds.

11 This feat of instantaneous mimicry has, over the past 12 decade, migrated from marine-biology journals into popular culture, where 13 headlines now routinely describe the octopus as the ocean's 14 genius, a creature that solves puzzles, escapes tanks, and 15 recognizes individual human keepers. Documentary narrators speak of octopus 16 "personalities" and "problem-solving," language borrowed wholesale from studies of 17 primates and crows. The word intelligence, once reserved for 18 animals with centralized brains and long memories, is applied 19 to a mollusk whose nervous system is scattered through 20 eight semi-autonomous arms.

21 It is worth pausing over that borrowed vocabulary, because the 22 octopus's camouflage, however dazzling, may be closer to reflex 23 than to reasoning. Neuroscientists who have studied the animal's 24 skin note that much of the color-changing response can 25 occur even in a severed arm, a piece of 26 tissue with no access to whatever passes for the 27 octopus's seat of judgment. If a disconnected limb can 28 still match the mottled gray of a rock, then 29 the marvel we are witnessing may say less about 30 cognition than about an extraordinarily elaborate, largely automatic reflex 31 arc.

32 None of this is to diminish the octopus, which 33 remains among the most startling creatures in the sea, 34 only to caution against a shortcut that has become 35 common in science writing: mistaking a spectacular capability for 36 evidence of a humanlike inner life. The same caution 37 might be extended to Venus flytraps, whose rapid snapping 38 is sometimes described as "deciding" to close, or to 39 slime molds, said to "remember" the shape of a 40 maze. Complexity of behavior and complexity of thought are 41 not the same measurement, however tempting it is to 42 conflate them.

43 What the octopus actually demonstrates, stripped of the borrowed 44 language, is that evolution can produce sophisticated outcomes without 45 anything resembling a plan. A distributed nervous system, refined 46 over millions of years by relentless predation pressure, arrived 47 at a solution neither centralized brains nor human engineers 48 have matched. That achievement needs no anthropomorphic embellishment to 49 be remarkable. It only needs precise description, and precise 50 description is, more often than field biologists would like 51 to admit, the harder story to tell.

The author cites the detail that a severed octopus arm can still change color (lines 24–27) primarily to:

1 Historians of American industry have long argued about how 2 to characterize the company towns that sprang up alongside 3 steel mills, textile factories, and coal mines between the 4 1880s and the 1930s. In the popular imagination these 5 towns survive as one of two caricatures: either grim 6 monuments to corporate control, where a single employer owned 7 every house, every store, and every church, and used 8 that ownership to crush any hint of labor organizing, 9 or as paternalistic utopias, built by enlightened industrialists who 10 supplied clean housing and modern plumbing decades before most 11 American cities managed the same. Both pictures contain some 12 truth, and both, taken alone, distort the historical record 13 more than they illuminate it.

14 Consider the town of Ardenmoor, built in 1897 by 15 a textile manufacturer along a Pennsylvania river valley. Company 16 records show that Ardenmoor's founder genuinely believed that decent 17 housing would produce a more reliable workforce, and he 18 was, by the standards of his era, unusually attentive 19 to sanitation, insisting on sewer lines that many nearby 20 independent towns lacked for another generation. Yet the same 21 records show that rent for company housing was deducted 22 automatically from wages before a worker ever saw a 23 paycheck, that workers who joined a union were evicted 24 within the week, and that the company store, which 25 advertised itself as a convenience, charged prices that kept 26 most families perpetually in debt. Ardenmoor was neither simply 27 generous nor simply predatory; it was an arrangement in 28 which genuine paternalism and genuine coercion operated through the 29 very same institutions, often within the very same transaction.

30 This is the point too many popular accounts miss. 31 When a writer insists that company towns were fundamentally 32 benevolent, pointing to the plumbing and the parks, that 33 writer must ignore the eviction records. When a writer 34 insists that company towns were fundamentally exploitative, pointing to 35 the evictions and the company store, that writer must 36 ignore the fact that workers themselves, in surviving letters 37 and union testimony, frequently distinguished between the housing they 38 valued and the control they resented, rather than condemning 39 the town as an undifferentiated wrong. A history that 40 cannot hold both of these truths at once is 41 not a simplification of the past; it is a 42 falsification of it, however useful that falsification might be 43 for whichever argument the writer wants the past to 44 support.

45 My aim in this essay is not to defend 46 company towns, nor to indict them further than the 47 record already does, but to insist that we resist 48 the tidy moral shape that both defenders and critics 49 have imposed on them. The residents of Ardenmoor did 50 not experience their town as a symbol. They experienced 51 a specific sewer line, a specific rent deduction, a 52 specific eviction notice, and a specific evening on a 53 specific porch that the company had, however self-interestedly, built 54 for them. Any history that flattens those particulars into 55 a single verdict, whether damning or admiring, has stopped 56 doing the work of history and started doing the 57 work of allegory. The company town deserves better than 58 allegory; it deserves the messier, less satisfying truth of 59 a past that refuses to sort itself into heroes 60 and villains.

The author's discussion of Ardenmoor's sewer lines and its rent-and-eviction practices (lines 16-29) primarily serves to:

1 When restorers speak of "cleaning" an old film, the 2 verb suggests something simple: wipe away the dirt, remove 3 the scratches, return the image to the condition it 4 had on its first night in a theater. In 5 practice, digital restoration is rarely so modest. Software can 6 now smooth grain, stabilize a trembling frame, sharpen a 7 blurred face, and correct a color that faded decades 8 ago into an unintended sepia. The temptation, once these 9 tools exist, is to use all of them, and 10 studios eager to sell a film to a new 11 generation of streaming subscribers often do exactly that.

The comparison to sanding brushstrokes off an oil painting (lines 35-37) primarily functions to:

1 For decades, the conventional wisdom among city planners was 2 that downtown commerce died at five o'clock and did 3 not resurrect itself until the next morning's coffee rush. 4 Storefronts went dark, sidewalks emptied, and the only economic 5 activity left was the occasional bar crowd stumbling between 6 last calls. That assumption is now being quietly dismantled 7 by a wave of night markets, an import — depending 8 on whom you ask — from Taipei, Bangkok, or simply 9 from the long human habit of trading goods after 10 the heat of the day breaks.

11 In Tulsa, a defunct rail yard now hosts nearly 12 eighty vendors every Friday between six and eleven, selling 13 everything from hand-pulled noodles to hand-tooled leather belts. City 14 officials did not create this market; they merely stopped 15 standing in its way, waiving a thicket of permitting 16 fees that had previously made pop-up food vending prohibitively 17 expensive for anyone without institutional backing. The result has 18 been a marketplace built almost entirely by people the 19 daytime economy had quietly excluded: immigrant cooks without capital 20 for a storefront lease, retirees supplementing fixed incomes, teenagers 21 testing whether a hobby could become a business.

22 Economists who study informal markets caution against reading too 23 much civic virtue into the trend. Night markets, they 24 point out, thrive partly because they escape the overhead 25 that crushes conventional small businesses — no year-round lease, no 26 full staffing, no insurance rider for a dining room 27 that does not exist. A vendor who loses money 28 on a rainy Friday simply does not show up 29 the following week; a restaurant that loses money on 30 a rainy month still owes rent. This flexibility is 31 precisely what makes the night market model appealing to 32 people just testing an idea, and precisely what makes 33 it a poor substitute for the tax base and 34 year-round employment that brick-and-mortar retail provides.

35 Still, something more than economics is visibly at work 36 when you walk the rows yourself. Strangers who would 37 not otherwise share a sidewalk after dark stand in 38 the same noodle line, trade recommendations, and linger past 39 the point of transaction. Several of the vendors I 40 spoke with described the market less as a business 41 venture than as a rehearsal for one, a low-stakes 42 place to learn whether their cooking, their leatherwork, their 43 jewelry could survive contact with actual paying customers before 44 they risked a real lease. That rehearsal function, more 45 than any single dollar figure, may be the market's 46 most durable contribution: it is quietly restocking the pipeline 47 of would-be small business owners that the traditional retail 48 model, with its upfront costs and long-term leases, had 49 been slowly starving.

50 Whether Tulsa's rail yard becomes a permanent fixture or 51 a passing curiosity will depend on decisions the city 52 has not yet made — about parking, about noise ordinances, 53 about whether success eventually invites the very regulatory apparatus 54 the market was born by avoiding. For now, though, 55 the lot fills up every Friday at six, and 56 by eleven, when the last vendor is folding tables 57 into a pickup bed, it is hard to argue 58 that anything downtown has been livelier in years.

The information about economists' caution regarding overhead costs (lines 22-34) primarily functions to:

1 When the restorers finished their eighteen-month project on the 2 ceiling fresco in the old chapel at San Ludovico, 3 the unveiling drew as much controversy as praise. Visitors 4 who had known the fresco only through decades of 5 soot and candle smoke suddenly found themselves looking up 6 at colors so vivid, so confidently blue and gold, 7 that several longtime parishioners complained the ceiling now looked 8 as if it had been painted last spring rather 9 than four centuries ago. The restorers, for their part, 10 insisted they had removed nothing but grime, and that 11 every pigment now visible had been applied by the 12 original hand of the master and simply obscured by 13 time.

14 The complaint, though it sounds like nostalgia dressed up 15 as connoisseurship, deserves to be taken seriously, because it 16 points to a genuine disagreement about what a restoration 17 is for. One school of thought treats the fresco 18 as a physical object whose original state is a 19 fact to be recovered, the way a document is 20 transcribed or a ruin is excavated: strip away later 21 accretions, and what remains is simply what the artist 22 made. A second school treats the fresco as something 23 closer to a living object, one whose meaning has 24 always included the patina it acquires, so that four 25 centuries of candle smoke are not a corruption of 26 the work but a record of the work's life 27 among the people who prayed beneath it, and to 28 strip that record away is to erase a kind 29 of history even while claiming to reveal one.

30 I do not think these two positions can be 31 reconciled by better chemistry or more careful brushwork. They 32 rest on different answers to a question that no 33 amount of technical skill can settle: whether a work 34 of art is most itself at the moment of 35 its making, or whether it is most itself as 36 the sum of everything that has happened to it 37 since. The restorers at San Ludovico clearly believe the 38 former, and within that belief their work was scrupulous, 39 even heroic, requiring solvents applied one square centimeter at 40 a time to avoid disturbing pigment that had waited 41 four hundred years to be seen again. But scrupulousness 42 in service of the wrong question does not make 43 the question right.

44 What troubles me most is not the brightness of 45 the new blues, which will, given another generation of 46 candle smoke, dim again regardless of anyone's philosophy. What 47 troubles me is the quiet assumption, built into the 48 restoration itself, that the fresco's true condition is whatever 49 condition it was in on the day the master 50 set down his brush, as though the intervening centuries 51 were merely an interruption to be corrected rather than 52 part of what the fresco has become. A parish 53 that prayed beneath darkened saints for four hundred years 54 has a claim on those saints that a restoration 55 committee, however skilled, cannot simply overrule in the name 56 of authenticity.

57 I do not begrudge San Ludovico its bright new 58 ceiling; I only wish the debate that produced it 59 had been conducted as openly as the solvents were 60 applied, so that the parish might have chosen its 61 own relationship to time rather than having one chosen 62 for it.

The author includes the observation that the new colors will eventually "dim again regardless of anyone's philosophy" (lines 44-46) primarily to:
