Read the following passage and answer the question.
Some parents at my nephew’s middle school want to eliminate group projects because “one kid always does all the work.” The complaint is familiar, but the proposed solution confuses a flaw in implementation with a flaw in the concept. In adult life, most meaningful work is collaborative, and the skill that separates competent employees from overwhelmed ones is not solitary brilliance but coordination: dividing tasks, setting timelines, and communicating when something breaks. If school avoids group work entirely, it teaches students that cooperation is optional rather than learnable. The better response is to design projects that make collaboration visible—individual checkpoints, peer evaluations, and rotating roles—so that freeloading becomes harder and leadership becomes measurable. The point is not to force friendship; it is to practice interdependence under guidance. Removing group projects would solve a short-term irritation by creating a long-term deficiency.
The passage’s logic advances the main claim by…
using an impatient tone to shame parents into accepting group work
asserting that group projects always create friendship, a claim the author explicitly denies
describing the parents’ complaint that one student does all the work, which is evidence but not the author’s reasoning
arguing that because collaboration is an essential adult skill, schools should improve the structure of group projects rather than eliminate them
Explanation
This question assesses the skill of explaining how an author's reasoning supports the thesis by identifying the logical connections that build the argument. The author establishes that collaboration is a vital real-world skill often mishandled in poorly designed projects. This premise leads to the reasoning that flaws in execution should prompt better structures, like checkpoints, rather than elimination. The logic connects this to the thesis that retaining and improving group work prevents long-term skill deficiencies. A distractor like choice A errs by presenting evidence as reasoning, without showing the logical link to preserving the practice. A transferable strategy is to trace the chain of reasoning from premises to conclusion, ensuring each step logically advances the thesis.
Read the following excerpt and answer the question.
In an editorial about disaster preparedness, an author argues that households should store water and basic supplies for at least three days. The thesis is not that people should “panic,” but that readiness is a form of civic responsibility. The author reasons that during storms or earthquakes, emergency services prioritize the most vulnerable and the most urgent rescues; if everyone immediately needs food and water, responders are diverted from life-saving work to routine distribution. Because public systems are designed to stabilize crises, not to replace individual planning, the author concludes that modest household preparation reduces strain on shared resources and indirectly protects neighbors.
The passage’s logic advances the main claim by…
linking the assumption that emergency services have limited capacity to the conclusion that personal preparation frees responders to focus on urgent rescues, making readiness a civic act
claiming that disasters are increasing every year, which is not stated in the excerpt
using a calm tone to reassure readers that preparedness is not panic
providing a list of recommended items, which is evidence and advice rather than an explanation of the thesis
Explanation
This question tests the skill of explaining how an author's reasoning supports their thesis. The author's reasoning connects the premise that emergency services have limited capacity during crises to the inference that unprepared households divert responders from urgent tasks. It concludes that personal stores reduce this strain, framing readiness as civic aid to neighbors and systems. This logical flow shows how preparation eases public burdens, advancing the thesis that it's responsible rather than panicky. Choice A incorrectly treats complaints as core reasoning instead of evidence supporting the civic angle. A transferable strategy is to connect individual actions to broader systemic benefits for a persuasive thesis.
Read the following passage and answer the question.
A state legislator has proposed requiring a full year of personal finance in high school. Opponents argue that students already learn “enough math” and that budgeting is something families should teach. But the proposal is not about adding more arithmetic; it is about teaching decision-making under constraints. Many graduates can solve for $x$ yet cannot compare a loan’s long-term cost or recognize how interest punishes minimum payments. When we pretend that financial literacy is private, we ignore that the consequences are public: debt defaults affect local economies, and predatory lending thrives on confusion. Schools teach civics because voting shapes the community; they should teach finance for the same reason. A course cannot guarantee perfect choices, but it can reduce the odds that young adults enter contracts they do not understand. Education does not replace family guidance—it creates a baseline of protection. In a market where mistakes are expensive, ignorance is not a neutral condition.
The passage’s logic advances the main claim by…
arguing that because financial decisions have public consequences and require applied judgment beyond basic math, schools should provide a baseline course to protect students
using alarming language about predatory lending to frighten readers into supporting the bill
restating that ignorance is not neutral, which repeats the conclusion without explaining how the author reaches it
listing that many graduates can solve for $x$ but cannot compare a loan, which is evidence but not the reasoning connecting school curricula to public outcomes
Explanation
This question assesses the skill of explaining how an author's reasoning supports the thesis by identifying the logical connections that build the argument. The author establishes that financial decisions impact public welfare and demand practical judgment beyond math. This premise connects to the reasoning that schools must teach finance to mitigate risks like debt, similar to civics education. The logic supports the thesis that a required course provides protective literacy for societal benefit. A distractor like choice C presents evidence as reasoning, without the logical tie to public consequences. A transferable strategy is to trace the chain of reasoning from premises to conclusion, ensuring each step logically advances the thesis.
Read the following passage embedded in this question:
A museum director argues that audio guides should be included in the ticket price rather than sold as an add-on. She explains that when guides cost extra, many visitors skip them, not because they dislike learning but because they assume the guide is optional “luxury.” As a result, visitors spend less time with each artwork and leave feeling that the museum is confusing or elitist. The director reasons that the museum’s value is not merely access to objects but access to understanding; if interpretation is paywalled, the institution undercuts its own educational purpose. She infers that bundling guides would raise the baseline experience for everyone and likely increase repeat visits and memberships. Therefore, she concludes, including audio guides is a strategic investment in the museum’s mission and long-term support.
The passage’s logic advances the main claim by…
listing the ways visitors can feel confused in museums to show that art is difficult
claiming that audio guides are the only way to understand art, so visitors without them learn nothing
arguing that charging separately discourages use of interpretation, which diminishes perceived value and undermines the museum’s educational mission, so bundling strengthens engagement
restating that guides should be included because museums should educate people
Explanation
This question asks you to explain how reasoning supports a thesis about including audio guides in museum tickets. The director's thesis advocates for bundled guides, and she supports this through analyzing educational mission: charging separately makes visitors skip guides thinking they're optional luxuries, leading to confusion and perceived elitism that undermines the museum's purpose of providing understanding, not just access. Her reasoning shows that bundling would improve baseline experiences and likely increase long-term support, making inclusion a strategic investment in mission fulfillment. Choice C incorrectly identifies this as circular reasoning, missing the specific analysis of how pricing affects perception and engagement. To identify strong reasoning, examine how pricing mechanisms influence behavior—here, how paywalling interpretation contradicts institutional purpose.
Read the following excerpt and answer the question.
A university administrator argues that requiring applicants to submit standardized test scores should be optional. He notes that the tests were designed to rank students under uniform conditions, but admissions decisions are not simply rankings; they are predictions about who will thrive in a specific environment. Because test preparation resources vary widely, a mandatory score can function less as a measure of readiness and more as a measure of access to coaching and time. When a metric is strongly shaped by unequal inputs, treating it as an objective yardstick introduces noise into the prediction the university actually cares about. Therefore, he concludes, optional submission preserves useful information for some applicants while preventing a single number from distorting evaluations for others.
The passage’s logic advances the main claim by…
stating that standardized tests were designed to rank students, which is background information but not the reasoning that supports the policy change
arguing that because admissions is a predictive judgment and test scores can reflect unequal access, making scores optional reduces distortion in evaluating readiness
claiming that standardized tests are always useless, a stronger claim than the author makes
restating that test scores should be optional, without explaining how the author links the purpose of admissions to the limits of the metric
Explanation
This question requires explaining how reasoning supports a thesis about optional standardized test scores. The administrator's reasoning distinguishes between ranking (what tests do) and predicting success (what admissions needs), then shows how unequal access to test prep makes scores reflect preparation resources more than readiness, introducing noise into predictions. This analysis of how the metric fails to measure what matters logically supports making scores optional to improve prediction accuracy. Choice B provides historical context but doesn't show the logical connection between test limitations and admissions goals. To identify strong reasoning, look for arguments that show why current practices fail to achieve their stated purposes.
Read the following passage embedded in this question:
A city council member argues that the public library should eliminate late fees. She notes that last year the library collected $18,000 in late fees, but staff spent roughly 900 hours processing disputes, issuing waivers, and handling payment problems. Those hours, she says, could have been used to run literacy workshops or keep the children’s room open longer. She adds that late fees function less like “accountability” and more like a barrier: patrons who fall behind by even a few dollars often stop borrowing entirely, which defeats the library’s purpose. Because the library already replaces missing books through its materials budget, the council member concludes that late fees are an inefficient way to encourage returns; reminders and temporary borrowing limits would motivate timely returns without pushing low-income patrons away.
The author’s reasoning supports the thesis by…
arguing that the administrative costs and deterrent effects of late fees undermine the library’s mission, making alternative incentives more logical
repeating that late fees should be eliminated because libraries should help everyone
listing the exact amount of revenue late fees generate in order to prove that the fees are morally wrong
using an angry, accusatory tone toward patrons who pay late, which pressures the council to act
Explanation
This question tests your ability to identify how reasoning supports a thesis about eliminating library late fees. The council member's thesis is that late fees should be eliminated, and she supports this through a cost-benefit analysis showing that processing fees consumes 900 staff hours that could be better used for literacy programs, while the fees themselves drive away patrons and defeat the library's purpose. This logical chain demonstrates that late fees are both administratively inefficient and counterproductive to the library's mission, making alternative solutions like reminders more sensible. Choice C incorrectly suggests mere repetition without logical support, failing to recognize the specific evidence about staff hours and patron behavior. When analyzing how reasoning supports a thesis, look for concrete evidence that connects to larger principles—here, the connection between resource allocation and institutional purpose.
Read the following excerpt and answer the question.
A homeowner argues that cities should legalize small backyard cottages (accessory dwelling units). Opponents say the change will “ruin neighborhood character,” but the homeowner notes that the city already allows home additions, garages, and basement renovations—changes that alter a property while keeping the lot and street the same. The real difference, she argues, is that a cottage adds a home for another person, and that prospect feels like a social change rather than an architectural one. Yet if a city claims to support teachers, service workers, and aging relatives living near their communities, it cannot treat additional neighbors as an automatic harm. Because the fear is based on an inconsistent standard—accepting structural change but rejecting new residents—she concludes that legalizing modest cottages is a coherent way to match zoning rules to the city’s stated values.
The passage’s logic advances the main claim by…
claiming that backyard cottages never affect parking or noise, a claim the passage does not make
providing a list of renovations like garages and basements, which functions only as evidence and not as an argument about standards
showing that the opposition relies on an inconsistent principle and inferring that zoning should align with the city’s professed values about who gets to live in the community
restating that backyard cottages should be legal, which does not explain how the author’s logic supports that conclusion
Explanation
This question tests your ability to explain how reasoning supports a thesis about legalizing backyard cottages. The homeowner's reasoning exposes an inconsistency: the city accepts physical changes to properties (additions, renovations) but rejects cottages primarily because they house additional people, revealing that opposition stems from social rather than architectural concerns. By showing this double standard contradicts the city's stated values about supporting community members' housing needs, she logically argues that consistent principles require allowing cottages. Choice B lists types of renovations as evidence but doesn't capture the logical argument about inconsistent standards. To identify strong reasoning, look for arguments that reveal contradictions between stated principles and actual practices.
Read the following passage and answer the question.
Our city council is debating whether to replace most street parking downtown with protected bike lanes. Critics cite a recent count showing that 78% of visitors arrive by car and warn that removing parking will “kill small businesses.” Yet this argument assumes that today’s travel patterns are fixed rather than shaped by design. When a street is built primarily for cars, it will predictably produce car dependence; when it is built to welcome bikes and walking, it will predictably produce more of both. The same shoppers who drive now are not genetically allergic to bicycles—they respond to safety and convenience. Moreover, the purpose of downtown is not to store vehicles but to connect people to stores. If a lane converts a dangerous corridor into a place where families can move comfortably, then foot traffic can rise even as parking falls. In other words, the relevant measure is access, not asphalt. Designing for access is how cities create commerce, not how they destroy it.
The passage’s logic advances the main claim by…
asserting that visitors are not “genetically allergic to bicycles,” which relies on humor rather than reasoning
listing the statistic that 78% of visitors arrive by car to show that bike lanes are unnecessary
claiming that protected lanes will automatically increase profits for every store, a certainty the author never argues
reasoning that travel behavior responds to street design, so changing infrastructure can change how people access businesses and thus support commerce
Explanation
This question assesses the skill of explaining how an author's reasoning supports the thesis by identifying the logical connections that build the argument. The author starts with the premise that travel patterns are not fixed but influenced by infrastructure design. This leads to the reasoning that car-dominated streets produce car dependence, while bike-friendly designs encourage alternative modes, increasing overall access to businesses. By linking design changes to shifts in behavior and commerce, the logic supports the thesis that bike lanes enhance rather than harm downtown vitality. A distractor like choice B misinterprets the statistic as opposing bike lanes, when the author uses it to challenge assumptions about fixed patterns. A transferable strategy is to trace the chain of reasoning from premises to conclusion, ensuring each step logically advances the thesis.
Read the following excerpt and answer the question.
In a newsletter to parents, a superintendent argues that the district should keep starting middle school later, even though some families dislike the schedule change. She concedes that earlier dismissal can make after-school logistics harder, but her thesis is that the later start is an academic policy, not a convenience policy. She reasons that middle schoolers’ sleep needs collide with early start times, and that chronic sleep loss reduces attention and emotional regulation—two conditions required for productive classrooms. If students arrive already depleted, teachers must spend instructional time managing behavior and re-teaching missed material. Therefore, she concludes, the schedule should be judged by whether it improves the conditions for learning, not by whether it preserves adult routines.
The author’s reasoning supports the thesis by…
linking the premise that sleep affects attention and regulation to the conclusion that start times should be evaluated by learning conditions rather than convenience
describing parents’ complaints about logistics, which functions as evidence of controversy rather than reasoning for the policy
repeating that later starts are an academic policy, which restates the thesis without showing why
claiming that later starts are popular, which is not presented in the excerpt’s logic
Explanation
This question tests the skill of explaining how an author's reasoning supports their thesis. The superintendent's reasoning links the premise that sleep deprivation impairs attention and emotional regulation to the need for schedules that optimize learning conditions. It infers that early starts deplete students, forcing teachers to manage fallout instead of teaching, which prioritizes convenience over academics. This chain shows why judging the policy by learning outcomes, not routines, justifies keeping later starts, reinforcing the thesis. Choice D mistakenly highlights repetition of the thesis without explaining the causal ties to sleep and classroom productivity. A transferable strategy is to map how evidence of problems leads to criteria for solutions, strengthening the main argument.
Read the following excerpt and answer the question.
In a district memo about student phone use, a principal argues that the school should adopt a “phones in lockers” policy during class time. She notes that teachers currently spend “several minutes per period” redirecting students from screens, and that even students who are not actively scrolling are “mentally braced for the next notification.” Her central claim is that removing phones from reach will improve learning more than simply tightening classroom consequences. She reasons that willpower-based rules treat distraction as a character flaw, but the environment is what repeatedly triggers attention; when the trigger is constant, consequences become a game of enforcement rather than a support for thinking. Because sustained focus is a prerequisite for reading complex texts and solving multi-step problems, she concludes that the policy change addresses the cause of inattention rather than its symptoms.
The author’s reasoning supports the thesis by…
using an urgent, admonishing tone to pressure readers into agreeing that phones are harmful
listing teachers’ complaints about lost minutes as sufficient proof that a new policy is necessary, without using any logical links
repeating that students are distracted by phones, which restates the thesis without explaining why a locker policy would work better than consequences
connecting the assumption that attention is shaped by environmental triggers to the inference that removing the trigger will improve focus more reliably than punishment-based rules
Explanation
This question tests the skill of explaining how an author's reasoning supports their thesis. The principal's reasoning begins with the premise that environmental triggers, like phone notifications, shape attention more than individual willpower. It then connects this to the inference that removing phones addresses the root cause of distraction, unlike consequences which only manage symptoms through enforcement. This logical progression shows why a locker policy would foster sustained focus essential for learning tasks, directly bolstering the thesis that it improves learning more effectively. In contrast, choice A incorrectly focuses on repetition without linking to why the policy is superior, missing the causal reasoning. A transferable strategy is to trace how premises about causes lead to conclusions about solutions, ensuring the logic bridges evidence to the main claim.
