AP English Language and Composition › Appropriate Evidence to Support a Claim
Read the passage and answer the question.
With droughts becoming more frequent in many regions, some cities are considering restrictions on ornamental lawns. Supporters argue that turf grass wastes water and offers little ecological value. Opponents argue that lawn restrictions limit personal choice and could reduce property values.
Cities should incentivize replacing lawns with drought-tolerant landscaping. This approach respects homeowners’ autonomy while steering neighborhoods toward sustainability. Rebates, free design templates, and native-plant starter kits can make the transition practical rather than punitive.
Paragraph 3: Reducing lawn irrigation can significantly cut residential water use. In many households, outdoor watering is a major portion of summer consumption, and drought-tolerant yards need far less. My neighbor replaced her lawn with gravel and says her water bill is “way lower” now. If more residents followed suit, the city could reduce strain on its water supply.
Incentives are not a cure-all, but they align individual savings with community resilience. When the next dry summer arrives, the city will be glad it acted early.
Which evidence would most effectively support the claim in paragraph 3?
A municipal water-utility report comparing metered summer water use for homes with irrigated turf versus homes with drought-tolerant landscaping, showing average gallons saved per month.
A photo of a beautiful native-plant garden in a nearby neighborhood.
A statement that wasting water is “morally wrong” and that people should feel ashamed of green lawns during droughts.
A landscaping company’s advertisement claiming xeriscaping is “the hottest trend” in home design.
Explanation
The skill of selecting appropriate evidence to support a claim involves choosing reliable, relevant information that strengthens an argument without relying on weak or biased sources. The correct answer, choice B, provides evidence directly supporting the claim that reducing lawn irrigation cuts residential water use by offering a municipal report with metered data comparing water savings between turf and drought-tolerant yards. This report uses average gallons saved per month, making it credible and relevant to quantify conservation impacts. By focusing on measurable comparisons, it strengthens the paragraph's argument about lowering summer consumption. In contrast, choice A is insufficient because an advertisement claims trends without data on water use. A key principle in writing is to draw on authoritative, data-backed sources to support environmental claims, promoting informed and sustainable arguments.
Read the following AP English Language–style argumentative passage and answer the question.
A community college is debating whether to make the first year tuition-free for residents, funded by a small increase in local sales tax. Supporters say it would expand opportunity; opponents say it would be too expensive.
(1) A tuition-free first year would be a practical investment in the region’s workforce. The local economy needs nurses, electricians, and technicians, and community colleges train for those roles faster than four-year institutions.
(2) The policy would also reduce the “stop-out” problem: students who begin college but leave because one unexpected cost derails them. When students can complete at least a year, they are more likely to earn a credential that raises lifetime earnings.
(3) Critics focus on the tax increase, but the cost should be weighed against the benefits. My uncle says he would have gone to college if it had been cheaper, and he still regrets missing that chance. A free first year would send a clear message that education is a public good, not a luxury.
(4) If the region wants to attract employers, it must show it can supply skilled workers. Making the first year tuition-free is not charity; it is economic strategy.
Replacement: Which evidence would most effectively support the claim in paragraph 3?
A statement that education is important because it helps people become better citizens and kinder neighbors.
A projection from the state labor department estimating increased credential completion and associated regional earnings gains compared with the projected sales-tax revenue needed to fund the program.
A moving story from a local resident who feels embarrassed about not having a degree.
A list of famous entrepreneurs who did not finish college but still became successful.
Explanation
The skill of selecting appropriate evidence to support a claim means choosing details that are relevant, data-oriented, and directly tied to weighing costs and benefits in an argument. Option B effectively supports the claim by providing a labor department projection that compares increased earnings from more credentials against the tax revenue needed, offering a balanced economic analysis. This evidence directly addresses critics' cost concerns by quantifying long-term regional gains, making the case for the policy's value. Moreover, it uses authoritative projections to demonstrate net benefits, strengthening the paragraph's focus on investment returns. Option A is insufficient because it relies on an emotional story of embarrassment, which does not provide fiscal comparisons or data. In writing, always incorporate evidence that quantifies trade-offs for economic claims, ensuring arguments are persuasive through facts rather than anecdotes.
Read the following AP English Language–style argumentative passage and answer the question.
A state legislature is considering banning smartphones during the school day in all public middle schools, with phones stored in locked pouches until dismissal. Some parents oppose the plan due to safety concerns.
(1) Schools have tried “phone-friendly” policies for years, and the results are predictable: constant buzzing, fractured attention, and conflict over enforcement. A statewide ban would remove ambiguity and make expectations consistent from school to school.
(2) The strongest argument for the ban is academic. Middle school is when students build habits of sustained focus, and frequent checking trains the brain to expect interruption. Teachers cannot compete with a device designed to capture attention.
(3) Opponents often raise emergencies, but schools already have communication systems for crises. In one online comment thread, several parents said they would feel ‘panicked’ if they couldn’t text their children at lunch. The legislature should prioritize learning conditions over adult anxiety.
(4) A phone ban will not fix every issue, but it will reduce a major, avoidable distraction. If students need technology for class, schools can provide it in controlled forms rather than relying on personal devices.
Evaluation: Why is the evidence in the bolded sentence insufficient?
It summarizes feelings from a comment thread, which does not establish how safety communication actually functions during emergencies or how common those concerns are statewide.
It provides too much statistical detail, making the paragraph difficult to understand for general readers.
It focuses on lunch periods even though the passage’s main claim is about after-school transportation.
It proves the opposite claim by showing that parents are always correct about school policy decisions.
Explanation
The skill of selecting appropriate evidence to support a claim requires evidence that is sufficient in scope, credible, and directly connected to the argument's needs. Option A correctly identifies the bolded sentence's weakness by pointing out that it summarizes subjective feelings from an online thread, failing to address actual emergency communication or the prevalence of concerns. This explanation supports the evaluation by underscoring the lack of factual depth and generalizability, which are essential for countering safety arguments in policy debates. Additionally, A highlights how such evidence does not engage with real systems, making it inadequate for the claim. Option B is misaligned because the evidence does not overwhelm with statistics; instead, it lacks any data at all. Remember, effective writing uses evidence that is objective and broad to support claims, avoiding reliance on unverified opinions that do not advance the argument.
Read the passage and answer the question.
As artificial intelligence tools become common, some schools are considering requiring an “AI literacy” course for graduation. Proponents argue students need to understand how algorithms shape information and opportunities. Critics argue graduation requirements are already crowded and that technology changes too quickly for a course to stay relevant.
Schools should require a basic AI literacy course because the technology already influences what students read, buy, and believe. The course does not need to teach advanced coding; it should teach how AI systems are trained, where bias can enter, and how to verify information. In a world of automated decisions, ignorance is not neutrality—it is vulnerability.
Paragraph 3: AI literacy is especially important because students are exposed to persuasive, personalized content online. Recommendation systems can amplify misinformation and push users toward more extreme material. One of my friends said her video app “always knows what I’m thinking,” and that scares her. If students feel uneasy, schools should respond.
A required course would give students shared vocabulary and tools for evaluating digital claims. It would also help families by making students better guides in their own homes.
Why is the evidence in the bolded sentence insufficient?
It offers detailed experimental findings about algorithmic bias, which are too advanced for the intended audience.
It proves that recommendation systems never influence users, so it contradicts the paragraph’s claim.
It focuses on classroom budgets rather than on students’ online experiences.
It is a subjective reaction that does not demonstrate how recommendation systems work or show measurable effects on student beliefs or behavior.
Explanation
The skill of selecting appropriate evidence to support a claim involves choosing reliable, relevant information that strengthens an argument without relying on weak or biased sources. The correct answer, choice A, effectively explains that the bolded sentence is insufficient because it is a subjective reaction that does not demonstrate how recommendation systems work or affect beliefs and behavior. This reason directly addresses how the evidence fails to provide concrete support for the claim that AI literacy counters persuasive content, as a friend's unease lacks analysis. By highlighting the subjective nature, choice A shows why this does not convincingly back the paragraph's assertion about algorithmic influence. In contrast, choice B is misaligned because the evidence offers no detailed findings. A key principle in writing is to use evidence that illustrates mechanisms and impacts rather than personal feelings to support claims about technology's effects.
Read the following AP English Language–style argumentative passage and answer the question.
A city council is debating whether to adopt a “housing-first” approach to homelessness, prioritizing permanent supportive housing over temporary shelters. The proposal would shift funds from emergency beds to long-term rental subsidies paired with counseling.
(1) Homelessness is often treated as a visible nuisance rather than a solvable policy problem. But the evidence from cities that prioritize permanent housing suggests that stability is not a reward for recovery; it is the foundation that makes recovery possible.
(2) Emergency shelters can keep people alive during extreme weather, yet they often cycle residents in and out without addressing the conditions that make homelessness persistent. People cannot reliably attend job interviews, medical appointments, or addiction treatment when they do not know where they will sleep next week.
(3) The council should adopt housing-first because it reduces long-term public spending. A friend who works at a downtown café says she sees the same unhoused customers every winter, and it feels like nothing changes. If the city invested in housing paired with case management, fewer people would remain stuck in repeated crises.
(4) Housing-first is not naïve about mental illness or addiction; it simply recognizes that treatment is far harder to begin and sustain without a stable address. The question is not whether shelters should exist, but whether they should remain the centerpiece of the city’s strategy.
Replacement: Which evidence would most effectively support the claim in paragraph 3?
A description of how discouraging it is for downtown workers to see the same people sleeping outside year after year.
An explanation of the moral belief that every person deserves a home regardless of their circumstances.
A statement from a local business association arguing that fewer encampments would improve tourism and city pride.
A peer-reviewed cost analysis showing that, over five years, supportive housing reduced per-person emergency-room and jail expenditures compared with shelter-only approaches in comparable cities.
Explanation
The skill of selecting appropriate evidence to support a claim requires choosing details that are directly relevant, credible, and sufficient to bolster the specific argument being made. Here, option A provides strong evidence by offering a peer-reviewed cost analysis that quantifies long-term savings from supportive housing, directly linking reduced expenditures in emergency services and jails to the housing-first approach. This data supports the claim about reducing public spending by comparing outcomes in similar cities, providing empirical proof of financial benefits over time. Additionally, the evidence is objective and verifiable, making it more persuasive for a policy debate focused on economic efficiency. Conversely, option B is insufficient because it relies on emotional descriptions of discouragement, which do not address cost savings and instead appeal to sympathy rather than fiscal impact. A transferable writing principle is to prioritize quantitative data from reliable sources when supporting claims about economic outcomes, as it lends credibility and specificity to the argument.
Read the passage and answer the question.
A university is considering making at least one “open educational resource” (OER) textbook option available for every required introductory course. Under the plan, faculty could still assign traditional textbooks, but departments would ensure a free or low-cost alternative exists.
Paragraph 1: Textbook prices have become a hidden tuition surcharge. Students can handle a challenging syllabus, but they cannot learn from a book they never buy.
Paragraph 2: When course materials are unaffordable, the consequences are academic, not cosmetic: students delay purchasing texts, share outdated editions, or attempt the class without the assigned reading.
Paragraph 3: The university should adopt the OER requirement for introductory courses. In my first year, I skipped buying a $240 biology textbook and still passed, so the price clearly doesn’t matter as much as people claim. If students can succeed without expensive books, the institution should stop treating high-cost texts as inevitable.
Paragraph 4: OER options also help instructors update content more quickly and reduce inequities between students who can buy every resource and those who cannot.
Evaluation: Why is the evidence in the bolded sentence insufficient?
It includes a specific price, which makes it too precise to be credible in an argumentative passage.
It focuses on biology rather than on the humanities, so it cannot be used in an argument about introductory courses.
It appeals to the reader’s sympathy for first-year students rather than presenting any factual information.
It is a single personal experience that cannot establish how textbook costs affect most students’ learning outcomes, and it may even undermine the passage’s broader claim that unaffordable materials harm learning.
Explanation
This question evaluates the skill of recognizing why certain evidence fails to support a claim about making open educational resources available. The correct answer (A) explains that the personal anecdote is insufficient because it represents a single experience that cannot establish broader patterns about how textbook costs affect most students' learning outcomes. More problematically, the evidence actually undermines the passage's central claim by suggesting that expensive textbooks don't matter since the student passed without buying one. This contradicts the argument that unaffordable materials harm learning, making it counterproductive evidence. Option B incorrectly focuses on precision rather than relevance, option C misunderstands the scope of introductory courses, and option D wrongly dismisses the factual content. When selecting evidence, writers must ensure their examples support rather than contradict their claims and represent patterns rather than exceptions.
Read the following AP English Language–style argumentative passage and answer the question.
A school district is debating whether to move the start time for high school from 7:20 a.m. to 8:30 a.m., adjusting bus schedules accordingly. Parents are concerned about after-school activities and childcare.
(1) A later start time is one of the simplest changes a district can make to improve student well-being. Teenagers’ sleep cycles shift later during adolescence, so early bells force many students to function on chronic sleep deprivation.
(2) Sleep deprivation affects more than mood; it affects learning. When students are tired, they retain less information, struggle to focus, and are more likely to skip school. If the district cares about academic performance, it should care about when students are expected to learn.
(3) The district should adopt the later start because it will improve achievement. Most people know that students do better when they’re well-rested. Even if schedules are inconvenient at first, the long-term benefits for grades and attendance justify the change.
(4) Districts that have made similar shifts often report fewer first-period tardies and calmer school mornings. The policy is not a cure-all, but it aligns the school day with adolescent biology rather than fighting it.
Replacement: Which evidence would most effectively support the claim in paragraph 3?
A survey of parents reporting that mornings feel less stressful when everyone can sleep later.
A student’s statement that waking up early is “unfair” and makes school feel like punishment.
A study comparing similar high schools before and after start-time delays, reporting measurable increases in attendance and course grades alongside increased average sleep duration.
A reminder that teenagers are growing quickly and therefore deserve compassion from adults.
Explanation
The skill of selecting appropriate evidence to support a claim requires details that are empirical, directly linked to the argument, and capable of demonstrating cause-and-effect relationships. Option B bolsters the claim by citing a comparative study showing improvements in attendance, grades, and sleep after start-time changes, providing measurable evidence of achievement gains. This data directly supports the idea of improved outcomes by linking later starts to specific academic metrics in similar schools. Additionally, the before-and-after design offers credible proof of the policy's impact, aligning with the paragraph's focus on achievement. Option A is insufficient because it uses subjective parent surveys on stress, which do not quantify academic improvements. In argumentative writing, prioritize evidence from controlled studies to support causal claims, ensuring arguments are grounded in verifiable results.
Read the following AP English Language–style argumentative passage and answer the question.
A university is considering a policy that would allow students to submit major assignments up to 48 hours late without penalty, no questions asked. Administrators say the policy would reduce stress; faculty worry it would undermine deadlines.
(1) The purpose of deadlines is not to punish students; it is to structure learning and keep courses moving. When deadlines become inflexible, they stop teaching responsibility and start rewarding only those whose lives are already predictable.
(2) College students balance jobs, family care, and mental health challenges alongside coursework. A small grace period can prevent a minor crisis—like a sudden shift change at work—from turning into a failing grade that permanently lowers a student’s GPA.
(3) Critics argue that a universal grace period would encourage procrastination, but the fear is overstated. In my freshman year, I once turned in a paper late and still learned a lot from writing it. A 48-hour window would be a humane default while still allowing professors to set firm cutoffs for time-sensitive work.
(4) Ultimately, the policy would not eliminate standards; it would clarify them. Students would know that one mistake will not define their semester, and instructors could spend less time adjudicating individual excuses.
Evaluation: Why is the evidence in the bolded sentence insufficient?
It is an isolated personal example that does not demonstrate whether a universal grace period affects procrastination rates across a student population.
It focuses on freshmen even though the policy would apply only to graduate students.
It provides too many numerical details about hours and grades for readers to follow.
It contradicts the passage’s position by proving that late work should always receive zero credit.
Explanation
The skill of selecting appropriate evidence to support a claim entails using details that are relevant, broad enough to generalize, and directly tied to the argument's core idea. Option A accurately explains the insufficiency by noting that the bolded sentence is an isolated personal anecdote, which cannot reliably show the effects of a grace period on procrastination across a larger student body. This evaluation supports the critique by emphasizing the lack of scope and representativeness, key flaws in evidence for policy arguments. Moreover, A highlights how such evidence fails to address population-level impacts, undermining claims about widespread behavioral changes. Option B is misaligned because it incorrectly suggests the evidence contradicts the passage, when it actually attempts to support it but falls short in scale. In writing, always opt for evidence that can be extrapolated to the broader context, such as studies or surveys, to avoid the pitfalls of unrepresentative personal stories.
Read the passage and answer the question.
A state legislature is considering a law that would require employers to post salary ranges in job listings. Supporters argue that pay transparency reduces discrimination and makes hiring more efficient; opponents argue that it will lead to conflict and reduce flexibility in negotiations.
Paragraph 1: Wage secrecy does not protect workers; it protects inequity. When employees cannot compare compensation, disparities can persist for years without challenge.
Paragraph 2: Pay transparency is not a cure-all, but it changes the default. Instead of forcing applicants to guess what a job is worth, it requires employers to state the value they claim the role provides.
Paragraph 3: The state should require salary ranges in job postings because transparency reduces pay gaps and saves time for both applicants and employers. In countries with stronger worker protections, people generally seem happier at work, which suggests transparency laws would also improve morale here. A clearer hiring process benefits everyone.
Paragraph 4: The policy can be written to allow reasonable ranges, updated periodically, and enforced through penalties for repeat noncompliance.
Replacement: Which evidence would most effectively support the claim in paragraph 3?
A chart showing that average wages have risen over the last 30 years, without connecting the trend to transparency policies.
A statement from a job influencer arguing that “everyone deserves to know their worth,” without data about hiring outcomes.
A peer-reviewed study comparing firms before and after adopting salary-range postings, finding reduced gender and racial pay disparities within job families and fewer late-stage offer rejections due to pay mismatch.
A description of one applicant who felt nervous negotiating salary and wished the employer had been more straightforward.
Explanation
This question tests the ability to select appropriate evidence for a claim about salary transparency requirements. The correct answer (A) provides the strongest evidence because it presents peer-reviewed research with specific, measurable outcomes directly related to the claim: reduced pay disparities and fewer late-stage rejections. This evidence uses a before-and-after comparison methodology that establishes causation rather than correlation, making it particularly compelling for policy arguments. Option B offers only opinion without data, option C provides an anecdote without systematic analysis, and option D presents irrelevant trend data unconnected to transparency policies. When supporting policy claims about workplace equity, writers should prioritize evidence that demonstrates measurable outcomes from comparable implementations, uses rigorous research methods, and directly addresses the specific benefits claimed in the argument.
Read the following AP English Language–style argumentative passage and answer the question.
A city is considering expanding protected bike lanes on major streets, removing some on-street parking to create physically separated lanes. The proposal has sparked debate among commuters and small businesses.
(1) Protected bike lanes are not just for avid cyclists; they are infrastructure that makes streets safer for everyone. When bikes and cars are forced to share narrow lanes, predictable conflicts occur. Separation reduces the chance of crashes and encourages more people to ride.
(2) More cycling can also reduce congestion. Each person who chooses a bike for a short trip is one less car competing for space at the busiest intersections. Over time, that shift can make bus service more reliable as well.
(3) Some business owners worry that losing parking will hurt sales, but the fear is often exaggerated. In a neighboring city, I visited a café on a street with bike lanes, and it was crowded on a Saturday afternoon. With thoughtful loading zones and clear signage, cities can support commerce while improving safety.
(4) The real question is whether the city wants streets designed only for cars or streets designed for people. Protected lanes are a concrete step toward a safer, more flexible transportation network.
Evaluation: Why is the evidence in the bolded sentence insufficient?
It is insufficient because it uses logical reasoning rather than emotional language about struggling small businesses.
It is irrelevant because it discusses safety even though the paragraph is only about climate change.
It is too specific because it names a café, which automatically makes the argument biased and therefore invalid.
It is a single observational anecdote that cannot establish whether bike lanes generally affect business revenue or foot traffic across many locations and times.
Explanation
The skill of selecting appropriate evidence to support a claim involves using details that are generalizable, credible, and directly relevant to countering specific objections. Option A rightly critiques the bolded sentence as a single anecdote about one café visit, which cannot establish broader effects of bike lanes on business revenue or traffic patterns. This evaluation supports the analysis by stressing the evidence's lack of scope across locations and times, a common flaw in addressing economic fears. Furthermore, A points out the inability to prove general trends, weakening claims about exaggerated worries. Option B is misaligned because the evidence is relevant to business impacts, not shifted to safety or climate. A transferable principle is to select evidence with wide applicability, like surveys or studies, to robustly support claims against counterarguments rather than isolated observations.
