Passage: Some organizations assume that the best way to improve employee performance is to measure it more frequently. Proponents of continuous monitoring argue that abundant metrics reveal problems early and deter complacency. Yet the passage notes that measurement can change what it measures: when workers know that only a few indicators are tracked, they may optimize those indicators even if doing so undermines unmeasured but important tasks. Moreover, frequent evaluation can increase short-term caution, discouraging experimentation whose benefits are uncertain and therefore hard to capture in near-term metrics. The author does not reject measurement outright; instead, the author contends that metrics are most useful when treated as prompts for inquiry rather than as definitive scores, and when they are paired with qualitative judgment that can notice trade-offs and context. The passage concludes that performance systems should be designed to learn from work, not merely to rank workers.
Question: The primary purpose of the passage is to…
demonstrate that continuous monitoring always improves productivity by deterring complacency
discuss workplace performance measurement
argue that performance metrics can be counterproductive unless they are used as tools for learning rather than as rigid scoring devices
explain how employees can manipulate a small set of tracked indicators to raise their evaluation scores
describe the history of workplace measurement from early factories to modern offices
Explanation
This question tests the primary purpose of the passage, which requires identifying the author's main objective in writing the text. A correct primary purpose answer captures the central argument while encompassing the passage's full scope. The passage develops its central point by first presenting the common assumption that frequent measurement improves performance, then systematically challenging this view by explaining how measurement can distort behavior and discourage innovation. The author builds toward a nuanced conclusion that metrics should be tools for learning rather than rigid scoring devices. Choice A correctly captures this primary purpose by identifying the author's argument that performance metrics can be counterproductive unless used as learning tools. Choice D is too vague and merely identifies the general topic without capturing the author's specific argument, while choice B incorrectly suggests a historical focus that doesn't exist in the passage.
Passage: When cities consider planting more trees to address summer heat, advocates sometimes imply that tree canopy is a universal remedy. The passage agrees that shade and evapotranspiration can lower local temperatures, but it emphasizes that the effect depends on placement, species, and surrounding infrastructure. For example, dense canopy over asphalt parking lots may reduce surface temperatures substantially, whereas scattered trees along wide, windy corridors may yield only modest cooling. The author also notes potential trade-offs: some species emit compounds that can contribute to ozone formation under certain conditions, and increased pollen can worsen allergies. Rather than treating tree planting as a symbolic gesture, the passage argues for integrating it with broader heat-mitigation strategies such as reflective materials and building design, and for evaluating outcomes with neighborhood-specific data.
Question: Which of the following best describes the main idea of the passage?
City governments should prioritize reflective roofing over planting trees because roofing has fewer trade-offs.
Tree planting can help reduce urban heat, but its benefits and drawbacks vary by context and should be planned as part of a broader strategy.
Dense canopy over asphalt parking lots produces the largest temperature reductions among common planting sites.
The passage is about urban trees and summer temperatures.
The passage catalogues every major method cities use to mitigate heat.
Explanation
This question tests main idea identification, requiring recognition of the passage's central claim about urban tree planting. A correct main idea answer must capture both the benefits acknowledged and the limitations discussed throughout the passage. The passage develops its central point by first acknowledging that trees can reduce urban heat through shade and evapotranspiration, then systematically presenting various contextual factors that affect their effectiveness. The author emphasizes placement, species selection, and potential trade-offs like ozone formation and allergies, ultimately arguing for a nuanced, data-driven approach. Choice B correctly captures this main idea by stating that tree planting can help but its benefits and drawbacks vary by context and require broader strategic planning. Choice A is too narrow, focusing only on one comparison mentioned in the passage, while choice D is too vague and fails to capture the passage's nuanced argument about contextual variability.
Passage: In discussions of language change, prescriptive commentators often portray new usages as signs of decline, implying that a language has a correct, stable form that is being corrupted. The passage evaluates this view by contrasting it with a descriptive perspective, which treats variation and change as normal features of living languages. The author notes that standards can be socially useful: shared conventions facilitate communication in formal settings and can reduce ambiguity. Yet the passage argues that elevating one variety as inherently superior often reflects historical power relations rather than linguistic necessity, and it can stigmatize speakers whose dialects differ from the standard. The author concludes that a balanced approach recognizes the practical role of standards while rejecting the notion that change itself is evidence of decay.
Question: The author’s main objective is to…
criticize descriptive linguists for ignoring the need for clarity in formal writing
argue that language standards are useless and should be eliminated from schools
discuss language change
provide a list of recent slang terms that have entered the language and explain their origins
evaluate prescriptive and descriptive views of language by acknowledging the utility of standards while disputing that change signals decline
Explanation
This question tests primary purpose, asking for the author's main objective in discussing language change. A correct answer must identify the specific evaluative argument being made rather than just stating the topic. The passage develops its argument by contrasting prescriptive views (which see change as decline) with descriptive views (which see change as normal), then evaluating both perspectives. The author acknowledges the utility of standards for formal communication while rejecting the notion that language change represents decay, ultimately advocating for a balanced approach. Choice D correctly identifies this primary purpose by stating the author evaluates prescriptive and descriptive views while acknowledging standard utility but disputing that change signals decline. Choice C is too vague and merely identifies the topic, while choice B misrepresents the author's position by suggesting standards should be eliminated, when the passage actually acknowledges their practical value.
Passage: In conservation policy, a common strategy is to designate protected areas and then treat the problem as largely solved. The passage argues that this approach can be misleading because protection on paper does not guarantee ecological outcomes. Boundaries may be porous, enforcement uneven, and local communities may bear costs without receiving benefits, creating incentives to circumvent rules. The author also notes that ecosystems are dynamic: species migrate, climate shifts, and threats such as invasive organisms do not respect administrative lines. The passage does not dismiss protected areas; it contends that they are most effective when embedded in broader governance that includes sustainable use zones, community participation, and monitoring that can adapt management as conditions change. In short, the author urges policymakers to focus on functioning institutions rather than solely on mapped territory.
Question: The primary purpose of the passage is to…
propose a global treaty that would standardize enforcement mechanisms across all countries
discuss conservation policy
explain how invasive species spread across administrative boundaries
claim that creating protected areas is ineffective and should be abandoned entirely
argue that protected areas alone are insufficient and must be supported by adaptive governance and community-engaged management
Explanation
This question tests primary purpose identification in a passage about conservation policy. A correct answer must capture the author's specific argument rather than just the general topic. The passage develops its central argument by first presenting the common strategy of creating protected areas, then systematically explaining why this alone is insufficient due to porous boundaries, uneven enforcement, and dynamic ecosystems. The author advocates for protected areas embedded in broader adaptive governance with community participation. Choice B correctly identifies this primary purpose by stating the author argues that protected areas alone are insufficient and must be supported by adaptive governance and community engagement. Choice C is too vague and merely identifies the topic, while choice D misrepresents the author's position by suggesting protected areas should be abandoned, when the passage actually advocates for improving rather than eliminating them.
Passage: Some critics of consumer credit argue that borrowing for everyday purchases is irrational because it involves paying more than an item’s sticker price. The passage responds that this critique overlooks the role of timing and uncertainty. For households with volatile income, access to credit can prevent costly disruptions—such as missed rent or utilities shutoffs—that may have larger long-term consequences than interest payments. However, the author also emphasizes that credit can amplify vulnerability when terms are opaque or when repayment depends on optimistic assumptions about future income. The passage therefore suggests evaluating credit not as inherently prudent or imprudent but as a tool whose value depends on contract design, borrower circumstances, and the availability of safer alternatives like emergency savings or social insurance.
Question: Which of the following best describes the main idea of the passage?
Credit card interest rates are too high and should be capped by law.
Consumer credit can be either stabilizing or risky depending on context, so it should be assessed as a conditional tool rather than dismissed wholesale.
The passage is about borrowing for everyday purchases.
Borrowing is irrational because it always causes households to pay more than an item’s sticker price.
The passage explains why households with volatile income often miss rent payments.
Explanation
This question tests main idea identification, requiring recognition of the passage's central claim about consumer credit. A correct main idea answer must capture both the benefits and risks discussed while reflecting the author's nuanced position. The passage develops its central point by first presenting critics' view that borrowing for everyday purchases is irrational, then explaining how credit can prevent costly disruptions for households with volatile income. The author balances this by acknowledging risks when terms are opaque or assumptions are overly optimistic, ultimately arguing for conditional evaluation based on context. Choice C correctly captures this main idea by stating that consumer credit can be either stabilizing or risky depending on context and should be assessed conditionally. Choice D is too vague and fails to capture the nuanced argument, while choice E oversimplifies by claiming borrowing is always irrational, directly contradicting the passage's discussion of situations where credit prevents larger costs.
Passage: Some educators defend timed, high-stakes exams on the grounds that they provide an objective measure of mastery. The passage challenges this assumption by distinguishing between mastery of content and mastery of test conditions. Time pressure, it argues, can privilege speed, familiarity with exam conventions, and anxiety management—traits that may correlate only imperfectly with deep understanding. At the same time, the author acknowledges that open-ended projects and take-home assessments can introduce other distortions, such as unequal access to resources or inconsistent grading. The passage therefore proposes a mixed approach: use multiple low-stakes measures across time, align each assessment format with the skill it is intended to capture, and interpret scores as evidence with limitations rather than as final verdicts. The goal is not to eliminate exams but to reduce the chance that any single format dominates judgments about learning.
Question: The author’s main objective is to…
argue that timed exams measure a combination of knowledge and test-taking conditions and should be balanced with other assessment methods
outline the psychological mechanisms by which anxiety impairs working memory during tests
discuss educational assessment practices
recommend that schools abolish all high-stakes testing immediately
prove that open-ended projects are always fairer than timed exams
Explanation
This question tests primary purpose, asking for the author's main objective in discussing educational assessment. A correct answer must identify the author's central argument rather than merely stating the topic. The passage develops its argument by first presenting the defense of timed exams as objective measures, then systematically challenging this by distinguishing between content mastery and test-taking skills. The author acknowledges problems with alternative assessments before proposing a balanced solution using multiple assessment formats. Choice A correctly identifies the author's objective: to argue that timed exams measure both knowledge and test conditions, and therefore should be balanced with other methods. Choice D merely identifies the general topic without capturing the specific argument, while choice B misrepresents the author's position by suggesting open-ended projects are always superior, which contradicts the passage's acknowledgment of their limitations.
Passage: Some managers view workplace conflict as inherently harmful, believing that harmony is a prerequisite for productivity. The passage questions this assumption by distinguishing between personal conflict and task conflict. Personal conflict—attacks on character or status—often corrodes trust and can indeed impede collaboration. Task conflict, however, can surface hidden assumptions, improve decision quality, and prevent premature consensus, especially when teams face complex problems. The author warns that task conflict does not automatically yield benefits: without norms that encourage respectful disagreement and mechanisms for integrating divergent views, it can easily slide into personal animosity or endless debate. The passage therefore recommends designing team practices—such as structured deliberation and clear decision rules—that preserve the informational value of disagreement while limiting its interpersonal costs.
Question: Which of the following best describes the main idea of the passage?
The passage discusses workplace conflict.
Managers should eliminate all conflict by enforcing strict behavioral rules in meetings.
The passage explains why personal conflict is more damaging than task conflict in teams.
Not all workplace conflict is harmful; task-focused disagreement can be productive if managed with appropriate norms and structures.
Conflict in teams is always beneficial because it prevents groupthink.
Explanation
This question tests main idea identification, requiring recognition of the passage's central claim about workplace conflict. A correct main idea answer must encompass the key distinction made throughout the passage and the author's nuanced position. The passage develops its central point by distinguishing between personal conflict (harmful) and task conflict (potentially beneficial), then explaining the conditions under which task conflict can be productive. The author emphasizes that benefits aren't automatic and require appropriate management structures and norms. Choice E correctly captures this main idea by stating that not all conflict is harmful and task-focused disagreement can be productive if properly managed. Choice D is too vague and merely identifies the topic, while choice C oversimplifies by claiming conflict is always beneficial, contradicting the passage's warnings about personal conflict and unmanaged task conflict.
Passage: Public discussions of automation often treat technology as an independent force that inevitably replaces human labor. The passage argues that this framing obscures the role of organizational choices. Whether a new system substitutes for workers or complements them depends on how tasks are redesigned, what training is provided, and which performance goals are prioritized. For instance, software that can draft routine reports might be used to reduce staff, but it might also be used to free staff to perform higher-value analysis—if the organization invests in developing those skills and adjusts incentives accordingly. The author acknowledges that some displacement is real, but contends that inevitability rhetoric can become self-fulfilling by discouraging experimentation with complementary designs. The passage’s main point is that the impact of automation is shaped by decisions, not just by machines.
Question: The passage is primarily concerned with which of the following?
providing a technical explanation of how modern software systems draft and summarize reports
arguing that the consequences of automation depend heavily on organizational decisions about task design and training
discussing automation in the workplace
describing how report-writing software can reduce staff in administrative departments
predicting that automation will eliminate most jobs within the next decade
Explanation
This question tests primary purpose, asking what the passage is primarily concerned with addressing. A correct answer must capture the author's central argument about automation rather than just identifying the topic. The passage develops its argument by challenging the view of technology as an independent force, instead emphasizing how organizational choices shape whether automation replaces or complements workers. The author provides examples of how the same technology can have different impacts depending on task redesign, training, and performance goals. Choice A correctly identifies this primary concern by stating the author argues that automation's consequences depend on organizational decisions about task design and training. Choice C is too vague and merely states the general topic, while choice D misrepresents the passage by suggesting it predicts widespread job elimination, which contradicts the author's emphasis on organizational choice.
Passage: Commentators often blame misinformation solely on individual gullibility, implying that better critical-thinking instruction would largely solve the problem. The passage argues that this view is incomplete because it treats information as if it were encountered in isolation. In practice, people receive claims through social networks that provide cues about trust and belonging, and platforms reward content that provokes quick reactions. Even a careful reader may share a dubious story if it signals loyalty to a group or if the cost of verifying it is high relative to the perceived stakes. The author does not deny the value of education; rather, the author contends that interventions must also address the environments in which information circulates—for example, by changing incentives for amplification and by making verification easier at the point of sharing. The passage’s broader point is that misinformation is a systemic phenomenon, not merely a cognitive failing.
Question: The passage is primarily concerned with which of the following?
explaining why critical-thinking instruction is useless in combating misinformation
discussing misinformation on the internet
describing the history of social networks and their role in political communication
showing that people share dubious stories primarily because they lack the ability to evaluate evidence
arguing that misinformation persists due to systemic incentives and social contexts, so solutions must go beyond individual education
Explanation
This question tests primary purpose identification, requiring recognition of what the passage is primarily concerned with addressing. A correct answer must capture the author's central argument about misinformation rather than just identifying the topic. The passage develops its argument by first presenting the common view that misinformation results from individual gullibility, then systematically explaining why this view is incomplete by discussing social networks, platform incentives, and group loyalty dynamics. The author builds toward arguing that solutions must address systemic factors beyond individual education. Choice C correctly captures this primary concern by identifying the author's argument that misinformation persists due to systemic incentives and social contexts. Choice D is too vague and merely states the general topic, while choice E contradicts the passage by oversimplifying the causes of misinformation sharing to lack of critical thinking ability alone.
Passage: In debates about scientific replication, one side interprets failed replications as evidence that original studies were careless or even fraudulent. The passage argues for a more cautious interpretation. A replication attempt may differ subtly from the original—using a different population, measurement instrument, or laboratory context—and such differences can matter when effects are sensitive to conditions. Moreover, the passage notes that even genuine effects can appear inconsistent because estimates vary with sample size and random noise; a single study rarely pins down an exact magnitude. The author maintains that replication is essential, but primarily as a means of mapping when and where an effect occurs, not as a simplistic pass–fail test of a study’s legitimacy. The passage concludes that the most productive replication culture emphasizes transparency, shared data, and cumulative evidence.
Question: The primary purpose of the passage is to…
argue that replication should be used to understand the conditions and variability of effects rather than to issue simple judgments about original studies
describe in detail the statistical formulas needed to compute sampling error
claim that most failed replications prove scientific fraud is widespread
discuss replication in science
explain how differences in measurement instruments alone account for all replication failures
Explanation
This question tests primary purpose, asking for the author's main objective in discussing scientific replication. A correct answer must identify the specific argument being made rather than just the general topic. The passage develops its argument by first presenting the simplistic view that failed replications indicate fraud or carelessness, then systematically explaining why this interpretation is problematic due to contextual differences and natural variability. The author advocates for using replication to understand conditions and variability rather than making simple pass-fail judgments. Choice A correctly identifies this primary purpose by stating the author argues replication should be used to understand conditions and variability rather than issue simple judgments. Choice C merely identifies the topic without capturing the specific argument, while choice D misrepresents the author's position by suggesting failed replications prove widespread fraud, which directly contradicts the passage's cautious interpretation.
