SAT Practice Test 4 - SAT Reading & Writing

1. Which choice completes the text with the most logical and precise word or phrase?
   Answer: accessible Because the brochure avoids jargon and aims to reach many readers, its tone is best described as accessible. Esoteric and ambiguous contradict the clarity described, and defiant mismatches the helpful, instructive purpose.
2. Which choice completes the text with the most logical and precise word or phrase?
   Answer: lucid The passage says curators wanted the explanations to be understandable for visitors with little background in archaeology. Lucid means clear and easy to follow, which directly matches that aim of accessibility. Concise means brief; the changes described—adding context, maps, and timelines—actually make the labels longer, not shorter, so brevity is not the goal. Esoteric means understood only by a specialized few, the opposite of what curators wanted for general audiences. Rigorous means thorough and exacting; while the passage protects rigor by refusing to oversimplify the research, that quality describes the underlying scholarship, not the goal for the explanations, which is being easy to grasp. Only lucid captures the intended clarity.
3. Which choice completes the text with the most logical and precise word or phrase?
   Answer: pragmatic Pragmatic' matches a data-driven, practical approach; 'theatrical' suggests showiness, 'capricious' implies unpredictability, and 'incendiary' implies provocation, none of which fit the context.
4. Which choice completes the text with the most logical and precise word or phrase?
   Answer: widespread Because both doctors and patients approved, the support was broad, making 'widespread' the best fit. 'Sullen,' 'perfunctory,' and 'reluctant' imply grudging or minimal support that contradicts the positive outcomes described.
5. Which choice best describes the function of the underlined sentence in the overall structure of the text?
   Answer: Offers a specific example that illustrates the precautions mentioned. The sentence provides a concrete example that supports the preceding point about contamination-control protocols. The other options mistake it for a thesis, a counterargument, or a formal definition.
6. According to the text, what event in 1974 prompted the excavations?
   Answer: Farmers found clay fragments while digging a well near Xi'an. The event that prompted the 1974 excavations is mentioned at the beginning of the history, where it reports that local farmers near Xi'an uncovered fragments of a clay figure while digging a well. The text directly states that 'in 1974, local farmers near Xi'an, China, uncovered fragments of a clay figure while digging a well,' and this discovery led to excavations revealing terracotta soldiers. Choice B confuses earlier rumors described by travelers with the specific 1974 event, as those accounts didn't prompt systematic searches. Choice C refers to a later conservation issue about pigments fading, which occurred after the excavations, not as the prompt for them. In detail questions, watch for answer choices that mix accurate details from different parts of the passage in misleading ways, and always pinpoint the exact section addressing the question.
7. Which choice best describes how Text 2 relates to the argument presented in Text 1?
   Answer: Text 2 concedes that EV benefits vary by grid but argues that EV subsidies should proceed alongside grid decarbonization rather than wait for it. Text 1 argues that EV subsidies should wait until grids decarbonize because charging EVs on coal-heavy grids provides 'little net gain.' Text 2 acknowledges this concern ('Grid cleanliness matters') but argues against delaying EV adoption. The key relationship is that Text 2 concedes the variability of benefits by grid composition while advocating for simultaneous progress: 'Subsidies for EVs and investments in cleaner electricity are complementary, not competing, strategies.' Choice B correctly identifies this nuanced response - Text 2 concedes the point about grid variation but argues for proceeding with both strategies rather than waiting. Choice A incorrectly claims Text 2 disputes grid emissions relevance. Choice C misrepresents Text 2 as agreeing EVs are ineffective. Choice D incorrectly suggests Text 2 avoids the subsidy question.
8. Which finding, if true, would most directly support the scholar's claim?
   Answer: In 46 towns, output per weaver rose by 15–20% within five years after public clocks were installed, independent of population growth and trade volume. The best answer reports that output per weaver climbed sharply soon after clocks appeared, while ruling out population growth and trade volume as causes. That combination matches the scholar's exact claim: clocks caused a productivity gain in ordinary craft work, above what commercial expansion alone would explain. The guild-profit finding ties gains to new trade routes, so it actually supports the critics' rival explanation rather than the clock hypothesis. The merchant's testimony describes a single individual's scheduling of shipments, which is the wrong scope—the claim is about broad craft production, not one businessman's revenue. The tax-register finding comes a full century later, far too delayed and too vague to show that clocks specifically caused the rise, and its slow, general pattern fits population and trade growth just as easily. Only the weaver data isolates clocks as the cause across a trade, which is what 'most directly support' requires.
9. Which choice most accurately represents information from the table?
   Answer: Site A is 9.8 µg/m³, lower than 10.4 µg/m³ or higher elsewhere. The report asserts that Site A has the lowest PM2.5 level, so we need to identify the minimum value. Looking at the concentrations: Site A has 9.8 µg/m³, Site B has 12.1 µg/m³, Site C has 10.4 µg/m³, and Site D has 13.0 µg/m³. Site A at 9.8 µg/m³ is indeed the lowest value. Choice A correctly states that Site A's 9.8 µg/m³ is lower than all other sites, which have 10.4 µg/m³ or higher. Choice D provides accurate data about the difference between Sites D and A but doesn't establish that A has the lowest level among all sites.
10. Which choice most effectively uses data from the chart to support the claim?
    Answer: Clinic A dropped from 45 minutes in 2022 to 30 minutes in 2024, a one-third reduction. Clinic A, the busiest in 2022 at 45 minutes, fell to 30 minutes in 2024, a one-third decrease. The other choices either do not address the busiest clinic, compute a different summary, or cite a statistic (median) not shown.
11. Which choice most logically completes the text?
    Answer: the smaller menu may have helped, but staffing and equipment changes could also explain faster service The passage describes three kitchen changes occurring over eight weeks: smaller menu, additional line cook, and oven replacement. The evidence shows ticket time dropped from 18 to 14 minutes, but we cannot isolate which change(s) caused this improvement. The correct answer (A) logically follows because each change could speed service—a smaller menu reduces complexity and decision time, an extra cook increases preparation capacity, and a functioning oven eliminates equipment delays—so the 4-minute improvement likely reflects combined benefits. Choice B illogically claims hiring slows service, choice C dismisses equipment importance without evidence, and choice D makes an unsupported universal guarantee. In restaurant operations, service speed depends on multiple factors working together; improving any bottleneck helps, but claiming single causation oversimplifies the system.
12. Which choice most logically completes the text?
    Answer: instrumental music improves reading speed, but topic familiarity and time of day may also have mattered The passage reveals that the music group read faster but also had two potential advantages: higher topic familiarity (which typically increases reading speed) and earlier testing time (when people may be more alert). With comprehension scores being equal, we cannot determine whether the music, familiarity, or time of day caused the speed difference. The correct answer acknowledges all three factors as potential contributors. Choice B illogically claims silence reduces comprehension despite equal scores. Choice C absurdly suggests music caused prior topic familiarity. Choice D dismisses time of day based on irrelevant comprehension data. In cognitive testing, participant characteristics and testing conditions often vary—the correct answer recognizes these confounding factors rather than attributing results to the intended variable alone.
13. Which choice most logically completes the text?
    Answer: the cereal's fiber may have helped, but journaling and exercise likely played a role The passage presents evidence of multiple factors contributing to an outcome, with a comparison group helping to parse their relative contributions. The evidence shows that the cereal group experienced decreased cholesterol but also exercised more due to journal tracking, while a journal-only group showed a smaller decrease, suggesting the journal (and resulting behavior changes) contributed to the effect. This pattern indicates that while the high-fiber cereal may have helped, the journaling and consequent increase in exercise likely played important roles. Choice A correctly recognizes these multiple contributing factors. Choice B incorrectly claims journaling always causes dramatic changes, Choice C wrongly identifies cereal as the sole method, and Choice D contradicts the evidence showing exercise increased. This demonstrates why health studies must track all behavior changes during interventions—participants often change multiple habits when they know they're being studied, a phenomenon called the Hawthorne effect.
14. Which choice most logically completes the text?
    Answer: the grain storage fee likely contributed to continued shortages even after shipping recovered The passage presents historical evidence showing how a policy change (the storage fee) correlates with continued problems even after the initial cause (reduced shipping) was resolved. The evidence traces a sequence: food shortages coincided with both reduced shipping and a new grain storage fee in 1847, then shortages persisted in 1848 despite normalized shipping until the fee was repealed. This pattern suggests the storage fee discouraged grain storage or distribution, contributing to ongoing shortages. Choice B correctly identifies that the fee likely contributed to continued shortages after shipping recovered. Choice A oversimplifies by ignoring the fee's role, Choice C makes an unfounded claim about historical sources, and Choice D overgeneralizes about tax effects. Historical analysis often requires examining multiple concurrent factors—economic policies like taxes and fees can have effects that persist even after other conditions improve.
15. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: they The antecedent 'selection committees' is plural, so the pronoun must be 'they.' 'It' is singular, and 'this' and 'these' are demonstratives that would be vague in this context.
16. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: has grown With "since," the present perfect "has grown" indicates growth from the past up to the present. The other tenses do not match the ongoing timeline: "had grown" and "grew" indicate that the growth has stopped, and "grows" misses the constency with "since" as a "started in the past and is still going" connotation. When you see the word "since" you should look for a verb tense that includes "has" (singular subject) or "have" (plural).
17. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: the following: water purification tablets Use a colon after 'the following' to introduce a list. A comma, semicolon, or no punctuation after this lead-in is incorrect.
18. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: had changed This question tests verb tense, specifically the past perfect to indicate an action completed before another past action. The phrase 'by the time the researchers returned in 2023' signals that the reef's change occurred prior to the return, so 'had changed' correctly uses past perfect to sequence these events. Choice A 'changed' is simple past, which doesn't show the prior completion; choice B 'has changed' is present perfect, inappropriate for a past context; and choice D 'will change' is future tense, which doesn't fit the timeline. In tense sequence questions, look for time markers like 'by the time' to determine if past perfect is needed for actions completed before other past events.
19. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: Saturday; however, the team A semicolon is needed before the conjunctive adverb 'however,' and a comma must follow it. The other choices either misuse a comma, omit needed punctuation, or misuse a colon.
20. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: proposals: one A colon properly introduces a list signaled by 'the following'. The semicolon (A) is incorrect because what follows is not an independent clause, and the commas in B and D do not appropriately introduce the list.
21. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: silent; the A semicolon correctly joins two independent clauses. The comma creates a comma splice, the colon is misused, and the last choice omits needed punctuation.
22. Which choice completes the text with the most logical transition?
    Answer: As a result, Cause/effect fits because the safety upgrades lead to shorter commutes and more customers. Contrast, addition, and time do not capture a direct result.
23. Which choice completes the text with the most logical transition?
    Answer: Subsequently Subsequently indicates a clear time sequence from the 1833 discovery to later industrial applications. However signals contrast, Moreover adds information without time-ordering, and Therefore emphasizes causation rather than chronology.
24. Which choice completes the text with the most logical transition?
    Answer: In the meantime, C marks a temporal relationship: these actions occurred during the postponement. Therefore suggests causation, However contrast, and Moreover mere addition, none of which capture the interim timing.
25. The student wants to emphasize cost savings for residents. Which choice most effectively uses relevant information from the notes to accomplish this goal?
    Answer: With plots expanding from 50 to 200 and participants reporting reduced grocery costs, the program helps more households cut food bills while city grants for supplies keep start-up expenses low. Choice B ties reduced grocery costs to expansion and grants that lower expenses. The other choices cite true notes about community engagement, infrastructure, or parks but do not directly address residents' cost savings.
26. The student wants to emphasize the environmental benefits of urban beekeeping. Which choice most effectively uses relevant information from the notes to accomplish this goal?
    Answer: Urban beekeeping boosts local ecosystems by increasing pollination of city vegetation and raising fruit yields near rooftop hives, supporting healthier community gardens without requiring large spaces for colonies. The best answer emphasizes environmental benefits: it draws on the notes about increased pollination and higher fruit yields, plus the point that colonies thrive without large spaces, all of which directly show how beekeeping helps city ecosystems. The choice about regulations—limiting colonies and requiring registration—accurately reflects a note, but it stresses safety and rules for neighbors, not environmental gains. The choice about local clubs and workshops focuses on education and responsible management, again a real note but about human behavior rather than environmental impact. The choice about straining forage uses the caution in the notes, but it highlights a potential drawback of beekeeping, the opposite of emphasizing benefits. Only the first choice synthesizes the notes that actually demonstrate environmental value.
27. The student wants to emphasize the environmental advantages of adaptive reuse compared with demolition and new construction. Which choice most effectively uses relevant information from the notes to accomplish this goal?
    Answer: Lifecycle analyses find reuse typically produces lower greenhouse emissions than comparably sized new construction, and demolition releases embodied carbon while generating significant waste, which weighs heavily against tearing down and rebuilding. The best choice draws together two notes about environmental impact: reuse typically produces lower greenhouse emissions than comparable new construction, and demolition releases embodied carbon while generating waste. Combining these directly supports the goal of emphasizing environmental advantages. The choice about higher upfront costs, financing, and timelines addresses economics, not environmental impact, so it misses the goal. The choice about tax credits and zoning bonuses also focuses on money and investment incentives rather than emissions or waste. The choice about high-performance new buildings highlights operational efficiency and utility costs; it actually praises new construction and never establishes reuse's environmental edge over demolition, so it works against the intended emphasis. Only the option pairing lifecycle emissions with demolition's carbon and waste completes the full environmental comparison the student wants.
28. Which choice completes the text with the most logical and precise word or phrase?
    Answer: approachable Plain language aimed at visitors without specialized knowledge suggests making the exhibit more approachable. The other options imply luxury, obscurity, or arrogance, none of which fit the intent to increase accessibility.
29. Which choice completes the text with the most logical and precise word or phrase?
    Answer: abundant Context describes overflowing crates and reduced shortages, indicating a large yield, so 'abundant' fits. 'Tentative' signals uncertainty, 'meager' contradicts the volume, and 'erratic' implies inconsistency.
30. Which choice completes the text with the most logical and precise word or phrase?
    Answer: indispensable Indispensable means essential, matching the claim that the checklist was key to reducing infections. Ornamental, capricious, and incidental suggest decorative, unpredictable, or minor roles that contradict the passage.
31. Which choice completes the text with the most logical and precise word or phrase?
    Answer: impetus Impetus is a driving force or motivation, fitting the context of enabling investment. Panacea means cure-all, anomaly means irregularity, and cachet means prestige—none denote motivating force.
32. Which choice best describes the function of the underlined sentence in the overall structure of the text?
    Answer: Provides a definition by describing effects The underlined sentence provides a definition by describing effects, explaining how unreliable narration works by forcing readers to infer motives from contradictions. It follows the introduction of unreliable narration in earlier novels and precedes a specific eighteenth-century example, thus clarifying the concept before illustrating it and noting nuances. This logical flow moves from historical context to definitional explanation to example to qualifications. Choice D might seem appealing as the sentence captures a core idea, but it defines the technique mid-passage rather than stating the central claim, which involves broader recognition requiring clues and context. In function questions, watch for how sentences bridge general ideas to specifics, like definitions leading to examples.
33. Based on Text 2, how would its author most likely respond to Text 1's suggestion that protected bike lanes generally increase local spending?
    Answer: They would contend that the economic effects vary by corridor and that bike lanes should be evaluated in context rather than assumed beneficial. Text 1 claims that protected bike lanes 'generally increase local spending' because cyclists and pedestrians make more frequent visits than drivers. Text 2 directly responds to this economic claim by stating that 'retail studies are mixed because outcomes depend on rent levels, regional commuting patterns, and whether customers can realistically arrive without a car.' This represents a qualification of Text 1's generalization - Text 2 doesn't reject the possibility of economic benefits but argues they vary by context. Answer C captures this relationship by stating the author would 'contend that the economic effects vary by corridor and that bike lanes should be evaluated in context rather than assumed beneficial.' Option A incorrectly suggests Text 2 prioritizes car throughput above all. Option B misrepresents Text 2 as agreeing with universal benefits. Option D falsely claims Text 2 advocates only for parking solutions.
34. Which choice best states the main purpose of the text?
    Answer: To argue that unexpected results can drive discovery. The author uses Fleming's story to argue that surprises and apparent failures can be productive. The other choices misstate the focus by narrowing it to biography or procedures or broadening it to the full impact of antibiotics.
35. Which choice best states the main idea of the text?
    Answer: The narrator wrestles with pride and loss as a sibling departs, revealing ambivalence about change. The narrator's mixed feelings at the sibling's departure underscore both affection and unease about change. The other options introduce vows, policy critique, or exhaustive chronology that are not present.
36. Which choice best states the main idea of the text?
    Answer: A notebook can help students transform errors into a learning routine. The central idea of the text is that a 'mistake notebook' can help students transform errors into a positive learning routine by encouraging reflection and pattern recognition. The passage as a whole focuses on Vega's description of the notebook's purpose, starting with how students record errors and notes on what misled them, then mentioning optional decorations and group readings, and culminating in its value for turning embarrassment into a method of noticing patterns and making better choices. This scope shows the notebook evolving from a simple record to a tool for building habits, with details like sketches and laughter serving to make the process engaging rather than punitive. A key distractor, choice A, focuses only on decorating as a way to increase investment, but this is a minor detail that doesn't capture the text's emphasis on the repeatable method of learning from mistakes. In central idea questions, ask yourself what the author spent the most space developing—that's usually the central idea, not the interesting details along the way.
37. Which finding, if true, would most directly weaken the scholar's claim?
    Answer: Stable isotope and ancient DNA analyses of burials from immediately before and after the pottery shift show continuity of local upbringing and ancestry. A shows demographic continuity across the ceramic shift, directly undermining a migration event. B is the wrong timeframe, C is a narrow anecdote, and D is correlational without demonstrating population movement.
38. Which choice best describes data from the table that support the note?
    Answer: Downtown measured 26, which is 9 higher than the park's 17. The teacher noted that downtown had the highest reading and exceeded the park site by 9 μg/m³, so we need to verify both claims. Downtown's reading was 26 μg/m³, which is indeed the highest (compared to Park: 17, Suburb: 19, Industrial: 24). The difference between Downtown and Park is 26 - 17 = 9 μg/m³, confirming the stated gap. Choice A correctly presents both facts. Choice B incorrectly identifies Industrial as having the highest reading when it's actually 24, not 26. Choice C states incorrect values for both sites. When a claim involves both identifying an extreme and calculating a specific difference, verify both parts match the data.
39. Which choice most logically completes the text?
    Answer: The coin could not have been manufactured before 1890. D necessarily follows from the coin's mint date stamped on it. A assumes site activity at that exact time, B overgeneralizes from one artifact to all, and C reverses cause and effect while assuming a layer date not established.
40. Which choice most logically completes the text?
    Answer: cannot be attributed solely to the citywide campaign. Because both sets of neighborhoods experienced the campaign but only the resurfaced ones saw larger reductions, the campaign alone cannot account for the difference. B is an unsupported leap to sole causation; C is a non sequitur about preferences; D reverses cause and effect.
41. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: had already The past perfect 'had already' is required to show completion before another past action ('reached'). 'Already have' and 'has already' are present-perfect forms that clash with the past-time frame, and 'will already have' incorrectly shifts to future. Only 'had already' matches the timeline established by the sentence.
42. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: the archivist The introductory modifier must logically modify the subject, so a person—the archivist—must be the one who discovered the notes. The other choices are inanimate and create a dangling modifier.
43. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: sends This question tests subject-verb agreement with compound subjects introduced by 'along with.' The subject 'the committee, along with its external advisors' treats 'committee' as singular, since 'along with' does not create a plural compound, requiring the singular verb 'sends' in present tense for the scheduled future action. Choice A 'send' is a base form that doesn't agree in number or function as a finite verb; choice B 'sending' is a participle, not a main verb; and choice D 'have sent' uses plural agreement and present perfect tense, mismatching the singular subject and simple future context. In agreement questions with phrases like 'along with,' remember that they add information but don't alter the main subject's number.
44. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: teachers' lounge Use the plural possessive 'teachers'' to indicate a lounge for many teachers. The other choices either imply one teacher, misuse the apostrophe, or create a number agreement problem with 'needs.'
45. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: orders: the salad station, This question tests the use of a colon to introduce a list that specifies or elaborates on the preceding clause. The part before the blank forms an independent clause ('the principal asked students to use three pickup points for lunch orders'), and the following items ('the salad station, the hot-food counter, and the grab-and-go fridge') directly identify those points, making a colon the proper connector. Both sides aren't independent clauses, as the list can't stand alone as a sentence, so a semicolon or period isn't suitable. Choice A incorrectly uses a comma, which can't introduce a list after a complete thought and risks a run-on feel; choice B misapplies a semicolon, reserved for linking independent clauses; choice D creates a sentence fragment by using a period. To spot when a colon is needed for lists, check if the preceding words form a complete sentence that the list explains or exemplifies.
46. Which choice completes the text so that it conforms to the conventions of Standard English?
    Answer: following: three Use a colon after 'the following' to introduce a list. A comma or semicolon is incorrect here, and omitting the punctuation makes the construction ungrammatical.
47. Which choice completes the text with the most logical transition?
    Answer: Consequently The logical relationship is cause-and-effect, as the second sentence describes positive outcomes resulting from the museum's redesign in the first. The first sentence outlines the aim to 'make exhibits more accessible,' and the second reports consequences like 'higher comprehension' and 'spent more time,' with 'surveys conducted after the change showed' linking the action to results. This direct causation requires 'Consequently' to connect the cause to its effects. Distractors such as 'Furthermore' add information without implying result, 'However' signals contrast that's not present in these aligned positives, and 'Still' suggests persistence despite opposition, which doesn't apply. A useful strategy is to trace causal chains—does the second sentence explain what happened because of the first?—to prioritize transitions like 'consequently' or 'thus.'
48. Which choice completes the text with the most logical transition?
    Answer: Moreover The logical relationship is addition, with the second sentence providing further details that refine the initial finding without contradicting it. The first sentence reports reduced emotional intensity from writing, interpreted as 'cognitive reappraisal,' and the second adds that 'the effect was strongest among participants who already had social support,' using 'also noted' to extend the interpretation. This supportive elaboration calls for 'Moreover' to introduce complementary information. 'Therefore' implies a conclusion drawn from the first, but it's an additional observation, 'However' signals contrast absent here, and 'Even so' suggests concession after opposition, which doesn't fit the alignment. When texts build on results with qualifiers like 'strongest among,' identify additive relationships to choose transitions that expand rather than conclude or contrast.
49. Which choice completes the text with the most logical transition?
    Answer: However, Contrast: the new evidence runs against the usual celestial alignment pattern. The other choices imply sequence, causation, or addition rather than opposition.
50. Which choice completes the text with the most logical transition?
    Answer: Even so, Concession: despite the green branding, studies indicate a counterintuitive drawback. The other transitions suggest causation, simple addition, or a comparison between two distinct items, none of which matches the concession.
51. The student wants to emphasize how community gardens boost urban biodiversity. Which choice most effectively uses relevant information from the notes to accomplish this goal?
    Answer: In Cityville, community gardens expanded native flowering plant coverage by 35 percent and supported 20 percent more urban pollinator species, aided by pesticide-free practices and added water sources for insects. Choice A uses biodiversity-related details: increased native flowers, more pollinator species, and supportive pesticide-free practices. B and D describe logistics and maintenance, not biodiversity; C makes false claims about synthetic pesticides and magnitude of change.
52. The student wants to emphasize the environmental impact of replacing diesel buses. Which choice most effectively uses relevant information from the notes to accomplish this goal?
    Answer: Replacing diesel models on the two busiest routes coincided with air quality monitors recording noticeable nitrogen dioxide drops, with the charging depot partly solar-powered, pointing to cleaner operation as a key outcome. Choice A ties the switch to recorded nitrogen dioxide reductions and cleaner energy use, directly addressing environmental impact. B and C discuss costs and operations, while D claims dramatic citywide reductions not supported by the notes.
53. The student wants to emphasize equity impacts for low-income commuters. Which choice most effectively uses relevant information from the notes to accomplish this goal?
    Answer: The pilot advanced equity because the corridors served predominantly low-income neighborhoods, and surveys showed 54 percent of new riders reported household incomes below the city median, indicating benefits concentrated among lower-income commuters. The student wants an option showing that the bus lanes helped low-income commuters in particular. The best answer does exactly that by combining two notes: the pilot corridors served predominantly low-income neighborhoods, and surveys found that 54 percent of new riders reported household incomes below the city median. Together those facts show who the benefits reached. The option reporting a 22 percent drop in travel times and on-time performance rising from 68 to 88 percent gives real results, but they are purely operational: faster, more predictable service tells you nothing about riders' incomes. The option about camera-based enforcement cutting bus-lane violations and improving compliance is likewise about how smoothly buses ran, not about equity. The option claiming that ridership among low-income residents doubled sounds on target, yet the notes never report any doubling, so it asserts a statistic the research does not contain. Only the grounded pairing of neighborhood demographics with the survey figure meets the goal.
54. The student wants to emphasize the limitation of biodegradable plastics in marine environments. Which choice most effectively uses relevant information from the notes to accomplish this goal?
    Answer: Despite their name, many biodegradable plastics persist in cool marine waters for months or years, fragmenting into microplastics ingested by plankton and fish, much like conventional plastics do. D directly addresses marine limitations—slow breakdown and microplastics ingestion. A and C are true but about waste systems or labeling, and B speculates about additives rather than demonstrating the limitation.

Take this practice test
