A decision before an answer
- Two authors can share a goal and disagree about the method. A comparison must preserve both levels.
- Your goal: Evaluate whether evidence supports a specific argument.
Read the relationship
- Identify each argument’s claim, evidence and limits separately before comparing texts. A criticism may concern method, cost or certainty rather than the goal itself. Relevance asks whether evidence bears on the claim; sufficiency asks whether its amount and quality warrant the conclusion. A counterexample can weaken a universal claim without disproving a narrower one.
- Compare agreement and disagreement across paired texts.
Where do the authors agree?
Both texts explicitly recognise evening access.
Use the defining rule
- For paired texts, make a two-column mental map of shared concerns and distinct positions. An answer can misrepresent both authors by combining one author’s evidence with the other’s conclusion. When predicting a response, use the responding author’s stated principle; do not invent a view simply because the authors disagree elsewhere.
- Integrate a graph or table without replacing the passage’s claim.
Which group has the highest waiting proportion?
10/18 exceeds 0.2 for both other groups.
Check the conditions
- Read a visual’s title, axes, units, groups and notes before using its values. A table may summarise observed counts rather than rates; compare denominators before interpreting a difference. Link the exact visual finding to the claim in the passage. A numerical trend does not establish a causal mechanism unless the design and text supply that support.
- Integrate a graph or table without replacing the passage’s claim.
Original Text A: “Extend opening hours first. The pilot recorded 18 evening visits across four evenings, so access after work is a real concern. Before buying more equipment, see whether a longer schedule spreads demand.” Text B: “Evening access matters, but schedule changes alone will not solve equipment queues. In the same pilot, ten of the eighteen evening visitors waited for a machine. Purchase decisions should use both attendance and waiting data.” Pilot table: morning 20 visits/4 waited; afternoon 30/6; evening 18/10. Both authors value access, but B says capacity also matters. Waiting proportions are 20%, 20% and about 56%, so evening has the highest waiting proportion despite the lowest visit count. This supports investigating an evening bottleneck; the observational pilot does not prove buying a machine is the best solution.
Six of thirty afternoon visitors waited: this is ____ percent.
6÷30×100=20; use afternoon visitors as the denominator.
Apply the task format
- The original paired case uses a compact table represented in words. It is targeted practice, not a full long Reading passage set. In a complete set, return between passage and visual as needed and answer the specified relationship rather than every interesting numerical pattern. Keep survey, pilot and measured outcome claims distinct.
- Integrate a graph or table without replacing the passage’s claim.
Counts are not rates, shared goals are not identical recommendations, and a four-evening pilot does not establish a universal causal claim.
Which answer fits this case?
Evaluate whether evidence supports a specific argument
The pilot proves that new equipment is the only solution.
The observations identify a problem but do not compare all remedies causally.
Keep the distinctions
- synthesis 综合 — Connecting ideas across sources while preserving their distinct claims.
- denominator 分母 — The reference total used when interpreting a proportion.
- Evaluate whether evidence supports a specific argument.
- Compare agreement and disagreement across paired texts.
- Integrate a graph or table without replacing the passage’s claim.
