Comparing two authors’ viewpoints

Paired passages often share a topic but differ in what they argue. A strong comparison identifies the relationship precisely instead of saying only that one author is “for” and the other “against.”

Build a two-column map

• Central claim: what each author wants readers to accept.
• Evidence: data, examples, expert statements or personal observations each uses.
• Assumptions: unstated links between evidence and conclusion.
• Purpose and audience: what the author is trying to accomplish and for whom.
• Tone and language: whether the author is cautious, skeptical, urgent or approving.

Find the exact relationship

Two authors may share a factual premise but draw different conclusions. One may support a policy in principle but oppose its implementation. Another may criticize the evidence rather than the goal. Use precise terms such as “both acknowledge,” “the second qualifies,” “the first relies on,” or “they disagree about the cause.”

Use evidence from both passages

A comparison answer needs support from each author. Locate the sentence that states the claim and the detail that demonstrates the contrast. Do not import outside knowledge or assume one author answers the other unless the passage says so.

Avoid common traps

• Confusing the author's description of an opposing view with the author's own position.
• Treating a difference in tone as proof of disagreement about the facts.
• Overlooking a qualification such as “usually,” “in this case” or “provided that.”
• Claiming one author refutes the other when they address different questions.

Compare more than a simple for-or-against position

Authors can share a broad goal but disagree about causes, evidence, timing, or the best solution. One may favor improving student attendance but support transportation changes; another may prefer family outreach because the author thinks scheduling is the main barrier. Saying only that both care about attendance misses the meaningful difference. A precise comparison names the dimension on which they align and the one on which they diverge.

Separate claim, evidence, assumption, and tone

A claim is what an author wants the reader to accept. Evidence is what the author uses to support it, such as a study, example, observation, or historical record. An assumption is the link between that evidence and the claim. Tone describes the author's attitude or manner—cautious, skeptical, urgent, or approving—but tone alone does not establish the claim. Two writers can use different tones while agreeing on the facts, or share a calm tone while reaching opposing conclusions.

For each passage, capture one claim and one piece of evidence in your own words. Then ask whether the evidence answers the same question in both texts. A personal account may illustrate how a policy affected one person; a survey may estimate how common the experience is. The sources can complement each other, but the anecdote does not establish prevalence and the survey may not explain an individual's experience.

Use a comparison matrix

• Issue: What exact question are both authors addressing?
• Shared ground: What fact, value, or goal do they both accept?
• Difference: Is the dispute about cause, scale, evidence, policy, or implementation?
• Support: What detail from each passage demonstrates that difference?
• Qualification: Does either author limit the claim by population, time, or condition?

Worked comparison

Suppose Passage One argues that schools should begin later because adolescent sleep schedules make early classes difficult, citing a local survey. Passage Two accepts that sleep matters but warns that changing start times can disrupt bus routes and after-school activities, citing implementation costs. A fair synthesis is that both treat student well-being as important, while the first emphasizes sleep and the second emphasizes logistical tradeoffs. It would be inaccurate to say Passage Two opposes student health; it questions one proposed way of improving it.

Choose comparison language with care

• Both authors acknowledge X, but only the first argues Y.
• The second author qualifies the first by limiting the recommendation to Z.
• The authors disagree about the cause of X, not about whether X occurs.
• The first relies on individual examples, while the second evaluates a larger data set.
• The passages address related but different questions, so neither directly refutes the other.

Verify the comparison against both passages

A strong answer needs a textual basis for each half of the comparison. Locate the evidence in Passage One and Passage Two, then check that the answer preserves each author's scope and certainty. Avoid broad labels such as “optimistic” or “pessimistic” unless the question asks about tone and the text supports them. If a claim is supported by only one passage, either narrow it to that author or choose a different comparison. This final check prevents an accurate summary of one text from becoming an inaccurate account of both.

State each author’s view before judging the difference

A viewpoint is an author’s position or perspective on an issue. Summarize each author separately in one sentence before comparing them. One may support an intervention while another questions whether the evidence justifies it. Avoid reducing a qualified position to a simple yes-or-no label; preserve the conditions and reservations each writer states.

Authors can agree on a goal but disagree about the best method. Both might want lower traffic injuries, while one recommends speed cameras and another favors street redesign. A comparison should name the shared objective and the different proposed mechanisms, rather than claiming the authors disagree about safety itself.

Compare reasons, evidence, and assumptions

A disagreement may concern evidence rather than values. One author may cite a controlled study; another may emphasize local experience or question whether the study population matches the community. Identify what each source measures and the assumptions connecting that evidence to the conclusion. Similar recommendations do not necessarily mean the writers rely on the same reasoning.

Tone can also differ: one author may be cautious, another urgent or skeptical. Infer tone from repeated language and framing, not a single adjective. If the authors use different levels of certainty, note that one argues a policy will work while the other says it may work under specific conditions.

Avoid merging or overstating positions

When writing a synthesis, attribute claims clearly: “The first author argues…” and “The second author responds…” This prevents a quotation or example from one passage from being assigned to the other. If one writer responds directly to the other, trace the exchange: what point is conceded, challenged, or left unanswered?

A strong comparison uses parallel categories—claim, reason, evidence, qualification, and tone—so similarities and differences are easy to see. Do not infer what an author would say about a new issue unless the stated principles support the inference. Keep conclusions within the passages’ scope and explain the textual basis.

• Summarize each author’s position independently.
• Separate shared goals from differing recommendations.
• Compare evidence, assumptions, tone, and certainty.
• Attribute quotes and claims to the correct passage.
• Use parallel categories and support every comparison with text.

Exam takeaway

Map each author's claim and evidence separately, then state the narrowest accurate relationship. Support every comparison with evidence from both texts.
