Question 1Reading Comprehension
A passage states that the author's brother 'left the village at dawn and never looked back.' In reading comprehension terms, what does the phrase 'never looked back' most likely convey about the brother?
- He planned to return within a few days.
- He was physically unable to turn his head.
- He was searching for something he had lost.
- He moved forward without regret or nostalgia. Correct answer.
Explanation
Idiomatic expressions must be read figuratively within context. 'Never looked back' signals a decisive break with the past and an absence of regret, which fits a departure scene. A literal reading of turning the head ignores the figurative force of the idiom.
Question 2Reading Comprehension
A paragraph opens with 'Cities across the region face a common problem.' The next three sentences describe traffic congestion, air pollution, and housing shortages. What is the function of the opening sentence?
- It offers a statistical estimate of the problem's scale.
- It provides a counterargument to the paragraph's main point.
- It introduces a general claim that the following details illustrate. Correct answer.
- It concludes the paragraph by summarizing earlier evidence.
Explanation
A topic sentence states the paragraph's controlling idea, and the sentences that follow supply supporting examples. Here the general claim is that cities share a problem, and the three details are instances of it. Recognizing this structure helps a reader separate main idea from supporting evidence.
Question 3Reading Comprehension
While reading a report, you encounter the word 'ubiquitous' in the sentence 'Smartphones have become ubiquitous in daily life.' Which context clue best helps you infer its meaning?
- The capitalization of 'Smartphones.'
- The phrase 'in daily life,' suggesting widespread presence. Correct answer.
- The contrast with a word in a later sentence.
- The length of the surrounding sentence.
Explanation
Context clues include the surrounding phrases that narrow a word's meaning. 'In daily life' implies that smartphones are found everywhere, which matches the sense of 'ubiquitous' as widespread. Structural features such as capitalization or sentence length carry no semantic information about the word.
Question 4Reading Comprehension
A reader is asked to identify the main idea of a short article. Which approach is most reliable?
- Pick the longest sentence in the final paragraph.
- Combine the topic and the author's central point about it. Correct answer.
- Select the sentence with the most difficult vocabulary.
- Choose the detail that appears first in the text.
Explanation
The main idea is a statement of the topic plus what the author asserts about it, often found by synthesizing topic sentences. Isolated details or impressive vocabulary do not capture the whole text's point. Summarizing in your own words is the standard way to verify a main-idea choice.
Question 5Reading Comprehension
In a passage, a character says, 'Of course I trust him,' then immediately changes the subject and avoids the person's name. What does this contrast between speech and behavior most likely suggest?
- The character's stated trust may be insincere. Correct answer.
- The character is unaware of the conversation.
- The character has forgotten the person's name.
- The character is being entirely sincere.
Explanation
When a character's words conflict with actions, readers should weigh both as evidence about motive. Avoiding the name and changing the subject undercut the verbal claim, suggesting hidden doubt. Reading comprehension often requires inferring unstated attitudes from such contradictions.
Question 6Reading Comprehension
A text says a policy was 'implemented with remarkable speed.' Which word in this phrase carries the judgment that the speed was unusual?
- speed
- remarkable Correct answer.
- with
- implemented
Explanation
Evaluative adjectives reveal the author's attitude toward a fact. 'Remarkable' frames the speed as noteworthy, whereas 'speed' alone is neutral. Identifying such loaded words helps readers detect tone and bias.
Question 7Reading Comprehension
A passage describes a scientist who 'spent decades refining a single experiment.' Which inference about the scientist is best supported?
- The scientist preferred working alone.
- The scientist was patient and persistent. Correct answer.
- The scientist achieved immediate fame.
- The scientist disliked other research topics.
Explanation
Inferences must follow from stated evidence rather than from speculation. Spending decades refining one experiment implies sustained effort and patience. The other options introduce attitudes or outcomes the text does not mention.
Question 8Reading Comprehension
When a reader encounters an unfamiliar term in an exam passage, which strategy best supports comprehension without wasting time?
- Assume the term means the opposite of the previous word.
- Stop reading and memorize the term's spelling.
- Reread the sentence and note how the term relates to nearby ideas. Correct answer.
- Skip the entire paragraph containing the term.
Explanation
Efficient readers use surrounding context to approximate an unfamiliar word's role and keep reading. Rereading the immediate sentence reveals relationships such as cause, example, or contrast. Abandoning the paragraph or guessing opposites sacrifices information the passage provides.
Question 9Reading Comprehension
A passage notes that a town's population 'doubled in five years,' then describes overcrowded schools and strained water supplies. What relationship do the later details have to the first fact?
- They contradict the population figure.
- They explain the causes of the population growth.
- They illustrate consequences of the population growth. Correct answer.
- They restate the population figure in different words.
Explanation
Cause-and-effect structure links an initial change to its outcomes. Rapid population growth is presented as the cause, and overcrowding and water strain are its effects. Distinguishing cause from effect is essential to accurate comprehension.
Question 10Reading Comprehension
An author writes: 'Some claim the new schedule saves money; however, the savings vanish once overtime is counted.' What is the author's position?
- The author doubts that the schedule truly saves money. Correct answer.
- The author is undecided and presents no view.
- The author believes overtime should be eliminated.
- The author fully endorses the new schedule.
Explanation
Contrast signals such as 'however' introduce the author's qualification or rebuttal. By noting that savings disappear after overtime, the author undermines the cost-saving claim. The stated counterpoint, not the initial claim, usually reflects the author's stance.
Question 11Reading Comprehension
A narrative shifts from past tense to present tense when describing a character's memories. What is the most likely purpose of this shift?
- To indicate the memories never actually occurred.
- To signal that the memories feel immediate and vivid. Correct answer.
- To mark a change in the narrator's identity.
- To show that the story has ended.
Explanation
Tense shifts in narrative often carry psychological meaning rather than mere chronology. Moving to present tense for memories can make them feel alive and pressing to the character. Readers should treat such stylistic choices as signals about emphasis or emotion.
Question 12Reading Comprehension
A passage presents two studies with opposite findings on the same question. Which statement best describes the passage's approach?
- It resolves the conflict by declaring one study invalid.
- It ignores the second study entirely.
- It juxtaposes conflicting evidence without a final verdict. Correct answer.
- It reports only the study with larger sample size.
Explanation
Some passages present competing evidence to show that a question remains open. Juxtaposition means placing findings side by side so the reader can weigh them. Recognizing an unresolved presentation prevents readers from overstating the text's conclusion.
Question 13Reading Comprehension
Read this sentence: 'The committee's decision, though widely criticized, was never reversed.' What does the sentence imply about the decision?
- It was never criticized by anyone.
- It remained in effect despite criticism. Correct answer.
- It was reversed after criticism.
- It was made unanimously.
Explanation
The concessive phrase 'though widely criticized' sets up a contrast with 'never reversed.' The sentence therefore indicates that criticism occurred but did not change the outcome. Parsing concession structures is key to precise comprehension.
Question 14Reading Comprehension
A writer describes a market scene with words like 'chaotic,' 'deafening,' and 'overwhelming.' What tone does this diction create?
- Intense and agitated Correct answer.
- Nostalgic and gentle
- Serene and contemplative
- Formal and detached
Explanation
Diction-the writer's word choices-shapes tone. Words such as 'deafening' and 'overwhelming' convey sensory intensity and disorder. Grouping connotatively similar words lets a reader name the tone accurately.
Question 15Reading Comprehension
A passage states: 'The bridge was completed in 1932, three years ahead of schedule.' Which question does this sentence answer directly?
- How much did the bridge cost?
- When was the bridge finished relative to plan? Correct answer.
- Who designed the bridge?
- Why was the bridge needed?
Explanation
Good comprehension questions test what the text explicitly supports. The sentence supplies a completion year and a comparison with the planned timeline. Cost, designer, and rationale are not addressed, so those questions cannot be answered from it.
Question 16Reading Comprehension
In an argumentative passage, the author cites an expert's opinion as support. What should a careful reader consider first?
- Whether the expert's name is easy to pronounce.
- Whether the expert's statement is the longest quotation.
- Whether the expert appears in other paragraphs.
- Whether the expert's credentials match the claim being made. Correct answer.
Explanation
Evaluating evidence requires checking relevance and authority. An expert's opinion supports a claim only when the expertise aligns with the subject at hand. Formatting features such as name length or quotation size are irrelevant to reliability.
Question 17Reading Comprehension
A passage says a character 'smiled, but her hands trembled as she folded the letter.' What does the physical detail most likely reveal?
- That she is cold in the room
- That she has never received a letter
- That she is amused by the letter's contents
- That she is concealing strong emotion Correct answer.
Explanation
Physical details often reveal feelings that dialogue or expression conceals. The trembling hands conflict with the smile, pointing to suppressed anxiety or distress. Readers should privilege concrete behavioral cues when interpreting emotional subtext.
Question 18Reading Comprehension
Which sentence uses a transition that correctly signals a contrast between two ideas?
- The proposal was costly; for example, it was approved.
- The proposal was costly; therefore, it was rejected.
- The proposal was costly; nevertheless, it was approved. Correct answer.
- The proposal was costly; similarly, it was approved.
Explanation
Contrast transitions such as 'nevertheless' connect an opposing idea to a preceding one. High cost and approval pull in different directions, so a concessive connector is appropriate. Other transitions signal result, similarity, or example, none of which fits.
Question 19Reading Comprehension
A paragraph begins with a question, then answers it with three supporting reasons. What is the rhetorical function of the opening question?
- To summarize the reasons that follow.
- To introduce the topic and engage the reader's attention. Correct answer.
- To attack an opposing viewpoint directly.
- To provide a counterexample to the thesis.
Explanation
Rhetorical questions often frame a topic and draw readers into the argument that follows. Here the question sets up the reasons as an answer. It does not summarize those reasons, since they come afterward.
Question 20Reading Comprehension
A text states: 'Not all technological change is progress; some innovations solve problems while creating larger ones.' Which assumption underlies this statement?
- Progress should be measured by overall consequences. Correct answer.
- Technological change is unrelated to problem-solving.
- All innovations are equally harmful.
- Innovation always produces net benefits.
Explanation
An assumption is an unstated premise needed for the claim to work. The statement treats progress as distinct from mere change, implying that progress depends on net effects. Without that premise, the contrast between innovation and progress would lose its force.
Question 21Reading Comprehension
An author writes that a reform 'was greeted with cautious optimism.' What does this phrase suggest about public reaction?
- People were indifferent to the reform.
- People were enthusiastic and certain of success.
- People were hostile and organized against it.
- People were hopeful but reserved in their expectations. Correct answer.
Explanation
Qualified expressions combine two attitudes and must be read as a whole. 'Cautious optimism' means hope tempered by doubt or restraint. Ignoring either word leads to an exaggerated reading of the reaction.
Question 22Reading Comprehension
Two passages discuss the same historical event. Passage A relies on eyewitness letters; Passage B relies on later statistical records. Which conclusion about the two passages is most defensible?
- Passage B contains no useful information about the event.
- Passage A captures personal experience while Passage B captures broader patterns. Correct answer.
- Passage A is necessarily more accurate than Passage B.
- Both passages must report identical details.
Explanation
Different source types illuminate different dimensions of an event. Letters convey subjective experience and detail, while statistics reveal aggregate trends. A careful reader compares the strengths of each source rather than ranking them absolutely.
Question 23Reading Comprehension
A passage argues that a city should expand public transit because 'every major city that invested in transit saw economic growth.' Which flaw most weakens this reasoning?
- It focuses on public transit rather than roads.
- It uses economic growth as a measure.
- It cites too many cities in the supporting evidence.
- It assumes correlation implies causation. Correct answer.
Explanation
The argument moves from an observed association to a causal claim. Growth may stem from other factors that coincide with transit investment, so correlation alone does not prove cause. Identifying this gap is central to evaluating an argument's strength.
Question 24Reading Comprehension
An author writes: 'To call this policy efficient is to ignore the workers it displaces.' What is the author doing with the word 'efficient'?
- Contesting the term by exposing what it overlooks. Correct answer.
- Using the term to praise the policy's designers.
- Accepting the term as an objective description.
- Defining the term for technical accuracy.
Explanation
Writers sometimes quote a term in order to challenge its framing. Here the author argues that 'efficient' hides human costs, effectively redefining the debate. Recognizing contestation of key terms is an advanced comprehension skill.
Question 25Reading Comprehension
A passage states that a discovery 'overturned a century of assumptions.' Which inference about the discovery is best supported?
- It concerned a topic with no prior research.
- It was ignored by the scientific community.
- It confirmed what researchers had long believed.
- It fundamentally changed established understanding. Correct answer.
Explanation
The verb 'overturned' signals a reversal of prior belief, and 'a century of assumptions' indicates long-held views. Together they imply a major shift in understanding. Confirmation or neglect would be expressed with very different verbs.
Question 26Reading Comprehension
A passage states: 'The museum's new wing opened to the public in March; by June, attendance had risen by forty percent.' Which conclusion is best supported by this sentence alone?
- Attendance was declining before the wing opened.
- The new wing was followed by a measurable increase in visitors. Correct answer.
- The new wing was the only reason attendance rose.
- The museum expects attendance to fall next year.
Explanation
The sentence reports two facts in sequence: an opening date and a later attendance figure. It supports only the claim that an increase followed the opening, not that the wing caused it or that earlier trends were negative. Causal and predictive claims go beyond what the text states.
Question 27Reading Comprehension
In a reading passage, a sentence begins: 'Although the trial produced promising results, ...' What does the word 'Although' signal about the information that follows?
- It repeats the results in different words.
- It gives an example of the results.
- It confirms the promising results.
- It limits or contrasts with the promising results. Correct answer.
Explanation
'Although' is a concessive connector, so the clause it introduces sets up a contrast or limitation to the idea already stated. The reader should expect the second part of the sentence to qualify the optimism of the first. Recognizing contrast signals helps a reader track an author's position accurately.
Question 28Reading Comprehension
A passage describes a proposal as 'a bold experiment whose costs remain unknown.' Which pair of attitudes does the phrase combine?
- Admiration and caution Correct answer.
- Hostile rejection and mockery
- Neutral description and indifference
- Confidence and certainty
Explanation
'Bold experiment' carries a note of admiration or interest, while 'costs remain unknown' introduces reservation. The phrase therefore blends approval with caution rather than pure praise or pure criticism. Mixed evaluative language is common in exam passages and should be read as a compound attitude.
Question 29Reading Comprehension
A paragraph opens with a general claim, then offers three specific cases that support it. What is the organizational pattern of the paragraph?
- Chronological sequence
- Generalization followed by illustration Correct answer.
- Comparison of two positions
- Problem and solution
Explanation
The paragraph states a broad claim and then supplies particular cases as evidence. This is the generalization-to-illustration pattern, which moves from a wide assertion to concrete support. Identifying the pattern helps a reader locate the main idea and the evidence attached to it.
Question 30Reading Comprehension
A passage says: 'The report was praised by reviewers who had not read the appendices.' What does the sentence most strongly suggest?
- The reviewers read the appendices carefully.
- The appendices are unimportant to the report.
- The appendices were written by the reviewers.
- The reviewers' praise may be based on incomplete reading. Correct answer.
Explanation
The qualifier 'who had not read the appendices' attaches a limitation to the reviewers' praise. The sentence implies that their judgment was formed without full access to the report. Careful readers notice such qualifying clauses because they quietly shape the reliability of the evidence.
Question 31Reading Comprehension
Which statement best describes the role of a topic sentence within an exam passage paragraph?
- It signals that the paragraph contains an opposing view.
- It introduces the paragraph's central idea, which later sentences develop. Correct answer.
- It supplies the final piece of evidence for the paragraph.
- It defines every technical term used in the passage.
Explanation
A topic sentence announces the paragraph's main point and is usually followed by supporting detail. Locating it lets a reader predict what the rest of the paragraph will do. It is not inherently a concluding statement or a glossary of terms.
Question 32Reading Comprehension
A reader is asked to identify an author's claim in a passage that includes many statistics. Which element should the reader prioritize?
- The longest sentence in the paragraph
- The date the passage was written
- The statement the statistics are offered to support Correct answer.
- The largest number in the passage
Explanation
Statistics function as evidence, and evidence exists to support a claim. The reader should locate the assertion that the data are meant to establish, which is the author's position. Numbers and sentence length are surface features, not the argument itself.
Question 33Reading Comprehension
A passage contains the sentence: 'The volunteers, exhausted but determined, finished the survey by nightfall.' What does the phrase 'exhausted but determined' mainly convey?
- The volunteers finished the survey easily.
- The volunteers completed the task despite fatigue. Correct answer.
- The volunteers abandoned the survey.
- The volunteers were unsure of the survey's purpose.
Explanation
The paired adjectives set fatigue against resolve, and the main clause confirms completion. The phrase emphasizes persistence in the face of difficulty. Reading participial phrases closely reveals the effort behind an outcome.
Question 34Reading Comprehension
An author writes: 'Critics of the plan raise valid concerns; nevertheless, the plan addresses a problem no one disputes.' What is the author's rhetorical strategy?
- Acknowledging objections while defending the plan Correct answer.
- Refusing to take a position
- Presenting the plan as flawless
- Rejecting the critics as uninformed
Explanation
The author grants that critics have a point, then uses 'nevertheless' to pivot to a reason for supporting the plan. This concede-and-counter move strengthens an argument by showing awareness of opposition. The author neither dismisses critics nor claims perfection.
Question 35Reading Comprehension
A passage explains that a drug worked in laboratory mice but notes that human trials have not yet begun. Which inference is most reasonable?
- The drug is unsafe for humans.
- The drug's effectiveness in humans remains untested. Correct answer.
- The laboratory results should be disregarded entirely.
- The drug is proven effective for humans.
Explanation
Results in mice establish only that the drug works in mice; without human trials, human effectiveness is unknown. The reader must keep the scope of evidence in view. Neither proven benefit nor proven harm in humans can be inferred.
Question 36Reading Comprehension
A passage states: 'The city council approved the budget after a debate that lasted well past midnight.' Which detail is emphasized by the phrase 'well past midnight'?
- The number of council members present
- The size of the budget
- The date the budget takes effect
- The length and intensity of the deliberation Correct answer.
Explanation
The time reference underscores how long the debate ran, implying sustained or contentious deliberation. It adds atmosphere and signals effort rather than supplying financial or procedural facts. Readers should notice how such details shape the impression of an event.
Question 37Reading Comprehension
In a passage, a researcher says: 'Our findings are preliminary.' How should a careful reader treat the study's conclusions?
- As deliberately misleading
- As tentative and subject to revision Correct answer.
- As final and ready for policy use
- As irrelevant to the research question
Explanation
The word 'preliminary' explicitly marks results as early and provisional. A careful reader should treat the conclusions as tentative pending further evidence. Hedging language of this kind is a signal to calibrate confidence.
Question 38Reading Comprehension
A passage presents a town's new recycling program as a success, citing reduced landfill waste but omitting any mention of program costs. What does the omission most likely indicate about the passage?
- The author opposes recycling.
- Landfill waste is unrelated to recycling.
- The program has no costs.
- The passage emphasizes benefits while leaving economic trade-offs unexamined. Correct answer.
Explanation
Selective inclusion of favorable data while omitting costs suggests a one-sided emphasis. A critical reader notes what is absent as well as what is present. The omission does not prove that costs are zero, only that they are not discussed.
Question 39Reading Comprehension
A passage uses the phrase 'a so-called solution' when referring to a proposed reform. What does the phrase imply about the author's view?
- The author is unfamiliar with the reform.
- The author doubts the reform actually solves the problem. Correct answer.
- The author endorses the reform strongly.
- The author considers the reform legally binding.
Explanation
'So-called' signals skepticism about whether a label is deserved. Applied to a 'solution', it suggests the author questions the reform's effectiveness. Readers should treat such quotation-style markers as indicators of the author's stance.
Question 40Reading Comprehension
A passage compares two explanations for a decline in bee populations, then concludes that both factors likely interact. What is the function of the conclusion?
- It repeats the first explanation only.
- It introduces a third unrelated explanation.
- It synthesizes the two explanations into a combined account. Correct answer.
- It dismisses both explanations.
Explanation
A conclusion that both factors interact draws the two explanations together rather than choosing one. This is synthesis: combining separate accounts into a fuller explanation. Recognizing synthesis helps a reader see how a passage resolves competing claims.
Question 41Reading Comprehension
A passage notes that a historical account was written by the winning side of a conflict. What should a reader consider about the account?
- It contains no factual information.
- It is automatically false in every detail.
- It may reflect the perspective and interests of the victors. Correct answer.
- It must have been written by a professional historian.
Explanation
Source perspective shapes what is emphasized, omitted, or framed. An account written by the victors may carry their interests and assumptions. A critical reader weighs this bias without assuming the account is wholly false.
Question 42Reading Comprehension
A passage states: 'Few residents attended the hearing; those who did spoke almost entirely about noise.' Which conclusion about the hearing is best supported?
- Noise was the dominant concern among attendees. Correct answer.
- Residents were satisfied with all other issues.
- The hearing was cancelled.
- Noise complaints were later resolved.
Explanation
The passage reports that nearly all speakers raised noise, supporting the conclusion that it dominated the discussion. Low attendance limits how much can be generalized but does not change what the attendees discussed. Claims about satisfaction or resolution are not supported.
Question 43Reading Comprehension
An author writes: 'The data are clear: emissions fell. What the data cannot tell us is whether the policy deserves the credit.' What distinction is the author drawing?
- Between two different pollutants
- Between local and national policy
- Between short-term and long-term data
- Between measurement and causation Correct answer.
Explanation
The author separates an observed measurement (falling emissions) from a causal claim (the policy caused the fall). This is the classic correlation-versus-causation distinction. Recognizing it prevents readers from accepting causal conclusions that the evidence cannot support.
Question 44Reading Comprehension
A passage describes a character who 'spoke little but listened to every word.' What does this contrast most likely suggest about the character?
- The character dominates conversations.
- The character is uninterested in others.
- The character is unable to speak.
- The character is attentive and observant. Correct answer.
Explanation
Speaking little while listening closely suggests attentiveness rather than disengagement. The contrast pairs restraint with careful observation. Character traits are often conveyed through such paired details rather than direct statement.
Question 45Reading Comprehension
A passage includes the sentence: 'Supporters point to lower costs; opponents cite lost jobs.' What is the passage doing at this point?
- Providing historical background
- Resolving the dispute in favor of supporters
- Describing a single unified viewpoint
- Presenting competing considerations without deciding between them Correct answer.
Explanation
The sentence balances two sides of an issue and reports each without adjudicating. This is a neutral presentation of competing considerations. A reader should note that the passage has not yet committed to either position.
Question 46Reading Comprehension
A passage about urban planning shifts from describing a problem to proposing a specific remedy. Which transition word would most likely mark that shift?
- In contrast
- Therefore Correct answer.
- For example
- Similarly
Explanation
Moving from a diagnosed problem to a proposed remedy is a consequential step, often marked by 'therefore' or 'thus'. Such connectors signal that a conclusion or recommendation follows from what came before. Contrast and example markers do different work.
Question 47Reading Comprehension
A passage reports that a study's sample consisted only of volunteers aged 18 to 22. What is the most significant limitation of the study's findings?
- The sample size was too large to analyze.
- The study used no measurements.
- The results may not generalize to other age groups. Correct answer.
- The volunteers were paid too much.
Explanation
A narrow age range restricts the population to which findings can be applied. Generalizability depends on how representative the sample is of the broader group. The passage gives no evidence of excessive size, absent measurement, or payment problems.
Question 48Reading Comprehension
An author writes: 'If we accept the report's premise, its conclusion follows; but the premise rests on a single survey.' What is the author's main point?
- The survey should be repeated by the author.
- The argument is valid in form but rests on weak evidence. Correct answer.
- The premise is irrelevant to the conclusion.
- The conclusion is false regardless of the premise.
Explanation
The author concedes that the reasoning is sound if the premise holds, then attacks the premise's support. This separates logical validity from evidential strength. The critique targets the foundation of the argument, not its internal structure.
Question 49Reading Comprehension
A passage states that a policy 'reduced waiting times by half' and elsewhere notes that the measurement excluded emergency cases. How should a reader interpret the reported reduction?
- As evidence that the policy failed
- As an accurate figure limited to non-emergency cases Correct answer.
- As proof that emergency care declined
- As a complete measure of the policy's effect
Explanation
The reported figure is accurate for the population measured but does not cover emergency cases. The reader must attach the stated scope to the statistic rather than generalizing it. Noting exclusions is essential when evaluating quantitative claims.
Question 50Reading Comprehension
A passage describes an invention as having 'arrived too early to be understood.' Which interpretation best captures the author's meaning?
- The invention's value was not recognized in its time. Correct answer.
- The invention was technically flawed.
- The invention was understood immediately.
- The invention was never built.
Explanation
'Too early to be understood' points to a mismatch between the invention and its era's readiness to appreciate it. The claim concerns reception, not technical quality or whether the device existed. Readers should distinguish judgments about timing from judgments about merit.
