High School Reading: Grades 9-10 Quiz: Analyzing Claim Development

"Critics call the plan costly. True, it costs more upfront, but it saves twice that within a decade." The word "True" mainly serves to:

"Libraries lend books. More quietly, they lend something rarer: a warm room where no one asks you to buy anything." The second sentence mainly serves to:

The Myth of the Lone Inventor

American schoolchildren learn that Thomas Edison invented the light bulb, that Alexander Graham Bell invented the telephone, and that the Wright Brothers invented the airplane. These stories share a common shape: a solitary genius, a flash of insight, a world transformed. The stories are memorable, which is why they are taught. They are also, in every case, wrong.

Edison filed his light-bulb patent in 1879, but by then at least twenty-three other inventors had already produced working incandescent lamps. Edison's contribution was not the bulb itself but a particular carbon filament—and even that filament emerged from a laboratory employing dozens of researchers whose names no textbook records. Bell filed his telephone patent on the same day, in the same office, as Elisha Gray, whose design was arguably superior. The Wright Brothers' 1903 flight was preceded by German glider experiments, French engine designs, and the aerodynamic research of a Scot named Percy Pilcher, who died testing his own machine in 1899.

The lone-inventor myth is not merely inaccurate. It is instructive in the wrong way. It teaches young people that innovation looks like a single mind striking against a problem in isolation. Actual innovation looks like a crowded room, and often like a courtroom afterward.

How does the author develop the claim that the "lone inventor" story is "instructive in the wrong way"?

In Defense of Boredom

Parents of a certain generation react to a child's complaint of boredom as if to a small emergency. A screen is produced; an activity is proposed; the vacuum is filled. This reflex is understandable but unfortunate. Boredom is not a defect to be corrected. It is a signal, and often a valuable one.

Psychologists studying creativity have observed that unstructured, understimulating time is precisely the condition under which the mind begins to generate its own material. A child who has nothing in particular to do will, eventually, invent something to do. The invention may be trivial—a game with sticks, a story told to a stuffed animal—but the capacity being exercised is not trivial. It is the capacity to originate rather than to consume.

When that capacity is never called upon, it atrophies. A child handed a device at every dull moment learns that dullness is intolerable and that relief comes from outside. The lesson is efficient and, once absorbed, extremely difficult to unlearn. Adults who cannot sit at a red light without checking their phones are showing us what happens.

None of this argues for cruelty. A bored child in a doctor's waiting room deserves a book. But a bored child in the backyard on a Saturday afternoon deserves the backyard.

The final paragraph functions primarily to:

Why Cities Grow Where They Do

Look at a map of major cities and a pattern appears. Almost all of them sit on water: an ocean coast, a navigable river, a lake, or the meeting of two rivers. This is not aesthetic preference. Before railroads, water was the only cost-effective way to move heavy goods over long distances. A ton of grain that could be shipped a thousand miles by barge for pennies would cost dollars to move the same distance by wagon. Cities without water access could not participate in the commerce that made cities worth building.

The railroad, arriving in the mid-nineteenth century, complicated but did not overturn this logic. New cities emerged at rail junctions—Chicago is the great example—but the older water-based cities generally kept their advantage, because rail lines were built to connect them. New York did not become less important when trains arrived; it became more important, because trains brought goods to its harbor.

Today, the argument continues in a new form. When a city ranks the reasons to relocate a business there, "proximity to a major airport" appears where "proximity to a deep-water port" once did. The specific technology changes. The underlying principle—that cities exist to reduce the cost of moving things and people—does not.

The reference to airports in the final paragraph primarily serves to:

Why We Misremember

Memory feels like a recording. When you recall your seventh birthday, it seems as if a small film is being replayed inside your head, faded perhaps but essentially intact. This impression is powerful and, unfortunately, wrong.

Memory is not retrieval but reconstruction. Each time you recall an event, your brain assembles it from fragments—a color here, a phrase there, a general emotional tone—and stitches them together into something that feels continuous. The stitching is guesswork, and the guesses are shaped by everything you have learned since the event occurred. A memory of your seventh birthday, recalled at thirty, has been reassembled perhaps a hundred times, each reassembly incorporating whatever you happened to be thinking, feeling, or hearing about at the time.

This is not a defect. Reconstruction is why memory is useful: a system that merely replayed the past would leave us no way to apply it to the present. But reconstruction has a cost. Confident memories can be entirely false. Eyewitnesses can describe, in vivid detail, events that did not happen. Two siblings can "remember" the same childhood incident in ways that cannot both be correct—and often neither is.

The implication is uncomfortable but important. When your memory and someone else's disagree, the honest answer is not that one of you is lying. It is that memory, in both of you, is doing what memory always does.

The author's claim that reconstruction "is not a defect" primarily serves to:

Sleep and the Adolescent Brain

When public-health officials call for later school start times, they are usually met with logistical objections: bus schedules, sports practices, working parents. These are real concerns. But they are not medical concerns, and the argument for later start times is a medical one.

Around puberty, the human circadian rhythm shifts. The hormone melatonin, which signals the brain to prepare for sleep, is released roughly two hours later in adolescents than in either children or adults. A fourteen-year-old told to be in bed by ten o'clock is, biologically, being told to sleep at eight. Most cannot. When the alarm rings at six the next morning, the same fourteen-year-old is being asked to wake at what her body registers as four.

The consequences are measurable. Districts that have moved high-school start times to 8:30 or later report reductions in tardiness, improvements in grades, and, most strikingly, sharp declines in teenage car crashes during the morning commute. Districts that have refused to move report none of these gains.

Critics sometimes suggest that teenagers should simply go to bed earlier. This suggestion, however well-meant, is the equivalent of suggesting that a person with a broken leg should simply walk normally. The biology does not permit it.

The author's comparison of early-morning waking to being asked to "wake at what her body registers as four" primarily serves to:

The Trouble with "Following Your Passion"

Graduation speakers love the phrase "follow your passion." It sounds generous. It flatters the graduates by assuming they already have a passion to follow, and it flatters the speaker by suggesting that he or she found one and did so. But as career advice, the phrase is close to useless, and for a specific reason: it inverts the actual relationship between interest and skill.

Research on job satisfaction consistently finds that people are not, in general, most satisfied doing what they initially loved. They are most satisfied doing what they have become good at. A cellist does not persist because she began with a passion for the cello; she persists because, after years of practice, she plays it well, and playing something well is deeply satisfying. The passion followed the competence, not the other way around.

Telling an eighteen-year-old to follow her passion, then, is telling her to look for something she does not yet have, in a place it does not yet exist. Better advice would be humbler: pick something plausible, get good at it, and see what develops. This sounds less inspiring on a stage. It has the advantage of being true.

The author's central claim is developed primarily by:

On the Overuse of the Word "Literally"

Critics of contemporary English are fond of pointing to the word "literally" as evidence that the language is decaying. When a teenager announces that she "literally died" during a movie, the critics wince and reach for their dictionaries. The word, they insist, means "in a literal sense," and using it to mean the opposite is a betrayal of meaning itself.

The complaint has a certain force, but it collapses under historical inspection. Charles Dickens used "literally" as an intensifier in 1839. So did Jane Austen, Louisa May Alcott, and James Joyce. If this is decay, the decay predates the complainers by nearly two centuries. What the critics are really objecting to is not a change in the language but a change in who is heard using it. When Dickens exaggerated, he was being witty. When a fifteen-year-old does the same thing on the internet, she is being sloppy.

Languages do not decay; they shift. The word "nice" once meant "foolish." "Awful" once meant "deserving of awe." No one mourns these losses because the speakers who caused them are safely dead. The living, unfortunately, keep talking.

The author's reference to Dickens, Austen, Alcott, and Joyce primarily functions to:

The Etiquette of Interruption

It has become fashionable to condemn interruption in conversation. Books and workshops on "active listening" instruct their readers to wait, to nod, to reflect back before speaking. This advice is not wrong, exactly, but it treats interruption as a single behavior when in fact it is at least two, and the two are opposites.

One kind of interruption is a power move. The interrupter is bored, or impatient, or believes that his contribution outranks the speaker's. He cuts in to close a topic, not to open one. This kind of interruption is what the workshops rightly condemn.

The other kind is the opposite. Linguists studying casual conversation, particularly among close friends and within certain regional and cultural communities, have documented what they call "cooperative overlap." The overlapper is not seizing the floor; she is signaling engagement, jumping in to complete a thought, agree, or amplify. To wait patiently in such a conversation is not politeness. It reads as disengagement, even coldness.

A rule that treats these two behaviors identically will misfire in one direction or the other. It will license domineering interrupters who follow the letter of the rule while breaking its spirit, or it will silence enthusiastic listeners whose overlap was never a problem in the first place.

The author develops the argument primarily by:

The Real Reason Museums Are Free

When visitors admire the free admission at institutions like the Smithsonian or Britain's National Gallery, they often assume the policy reflects a democratic ideal: art belongs to everyone, and no one should be priced out. This is not false. But it obscures a more practical calculation that shaped the policy from the beginning.

A museum that charges admission must count its visitors and justify its budget by attendance figures. It becomes, in effect, an entertainment business, competing with movie theaters and amusement parks for weekend traffic. Its curators face constant pressure to mount blockbuster shows featuring familiar names, because obscure exhibitions do not sell tickets. Scholarship gives way to spectacle.

A free museum is under different pressures. It can mount an exhibit on eighteenth-century Dutch drawings, attract three hundred serious visitors, and count the exhibit a success. It can serve researchers and schoolchildren without asking whether they "paid their way." Its mission remains scholarly rather than commercial, not because its curators are more noble but because the funding structure permits it.

The democratic argument for free museums is easier to explain to donors. The structural argument is the one that keeps the museums serious.

How does the author's claim in the final sentence relate to the passage as a whole?

The Case Against Lawns

The American lawn covers roughly forty million acres—more land than is devoted to any single irrigated crop, including corn. It produces nothing edible. It supports few pollinators. In many western states, it consumes more water than the households it surrounds. And yet homeowners spend, in aggregate, tens of billions of dollars each year to maintain it.

Why? The lawn is a relic of eighteenth-century English estates, where a stretch of closely cropped grass was a visible declaration that the owner could afford to devote productive land to mere display. Grass, in other words, was a boast. It said: I do not need this field to feed my family. When the fashion crossed the Atlantic, it kept its meaning but lost its context. A duke's lawn made sense; a suburban quarter-acre's lawn is a duke's boast in miniature, made by people who are not dukes.

Critics of the lawn are often accused of wanting to abolish beauty. This is a misreading. The alternatives—native grasses, wildflower meadows, vegetable gardens, moss—are not ugly. They are simply different. What critics want to abolish is not beauty but a particular inherited definition of it, one whose original logic no longer applies.

Which choice best describes how the second paragraph advances the author's overall argument?

Reading in the Age of Screens

Every few years, a study appears announcing that young people are reading less than they used to. The studies are usually accurate but rarely useful, because they define "reading" as engagement with printed books of a certain length. By this definition, a teenager who spends four hours a day on the internet is not reading. This is absurd on its face. She is doing almost nothing but reading.

The more honest question is not whether young people read but what they read and how. Here the news is genuinely mixed. Screen reading, research suggests, tends to be faster, more fragmentary, and less retentive than book reading. A person scanning a webpage catches perhaps a quarter of its content. The same person, given the same text on paper, catches nearly half.

But this comparison, too, can mislead. It measures screen reading against book reading, when the fair comparison might be against not reading at all. A teenager scrolling through news headlines, comment threads, and short articles is absorbing something. Whether she would otherwise be reading Dostoyevsky or watching television is a question the studies rarely ask, and the answer probably varies by teenager.

In the third paragraph, the author's discussion of what teenagers "would otherwise be" doing functions to:

The Quiet Revolution of the Bicycle

When historians catalog the inventions that reshaped daily life in the nineteenth century, the bicycle rarely receives top billing. The steam engine and the telegraph tend to crowd it out. Yet the bicycle deserves closer attention, precisely because its influence was social rather than industrial. Before the safety bicycle appeared in the 1880s, a woman of the middle class rarely traveled beyond walking distance without a chaperone or a carriage. The bicycle changed that arithmetic overnight. It was cheap enough for a clerk to afford, simple enough for a teenager to repair, and, critically, it required clothing that permitted movement.

Dress reformers had argued for decades that corsets and floor-length skirts were unhealthy, but their pamphlets persuaded few. The bicycle persuaded everyone. A woman could not pedal in whalebone; she could not steer in twelve pounds of petticoat. Within a decade, bloomers and shortened skirts appeared in catalogs that had previously refused to stock them. Susan B. Anthony, never given to overstatement, called the bicycle the machine that had "done more to emancipate women" than any other single thing.

The point is not that the bicycle caused suffrage or that its inventors intended a social revolution. They did not. The point is that a technology designed for locomotion produced, almost as a byproduct, a rearrangement of what women were permitted to wear, where they were permitted to go, and, eventually, what they were permitted to imagine.

How does the author develop the claim that the bicycle's importance was "social rather than industrial"?
