Many wrong answers are not absurd. They are carefully written statements that become persuasive only after the reader supplies a missing cause, motive, definition, or universal rule. Inference accuracy improves when you identify that hidden addition.

The Inferences skill

Valid inference
A conclusion that follows logically from the text's explicit facts and strongest implications without requiring unsupported information.

Turn the passage into premises

Separate observation from explanation. If participation rose after a schedule changed, the sequence is evidence; it does not by itself prove that the schedule was the only cause or reveal why every participant joined.

Evidence, inference, and assumption

Supported bridge

Directly connects stated facts. Example: A later time may improve access for some workers.

Hidden cause

Invents an exclusive explanation. Example: Timing was the only reason attendance changed.

Hidden motive

Assigns an unreported preference. Example: Every worker prefers afternoons.

Control scope and certainty

A repeatable method

Premise-to-conclusion workflow

  1. Underline claims

    Identify exactly what each answer asserts—not just its familiar words.

  2. Name the bridge

    Complete: ‘For this answer to work, the text must also show that …’

  3. Search

    Check whether the passage actually supplies that missing information.

  4. Prefer economy

    Select the answer that adds the least while explaining all relevant facts.

Worked SAT-style example

Worked example

Follow only what the text supports

A town moved a public workshop from weekday mornings to Saturday afternoons. Registration then included more full-time workers than before. The town did not ask registrants why they attended. The evidence therefore suggests that ______

Question: Which choice most logically completes the text?

  1. the new time may have made the workshop accessible to some workers who could not attend before
  2. every full-time worker prefers afternoon events
  3. the schedule change was the only reason registration changed
  4. morning workshops provide less useful information than afternoon workshops
  1. Extract

    The stated change is timing; the observed outcome is a different participant mix.

  2. Connect

    Because motives were not surveyed, the conclusion must stay tentative.

  3. Verify

    Accessibility is a reasonable link, but universal preference, sole cause, and content quality are not established.

The new time may have made the workshop accessible to some workers who could not attend before.

Why each choice works or fails

  1. Correct: it makes a limited, plausible connection and preserves ‘may’ and ‘some.’
  2. Overgeneralized: no preference survey supports every worker.
  3. Causal overreach: other influences were not ruled out.
  4. Irrelevant assumption: the information's usefulness was never compared.

Mini check

After a café added outdoor tables, weekend sales rose. Weather and advertising were not tracked. Which inference is defensible?

  1. The added seating may have contributed to the increase.
  2. Outdoor seating was the sole cause of the increase.
  3. All customers prefer eating outside.
  4. The café stopped advertising.
Show answer and explanation

Answer: The added seating may have contributed to the increase.

The timing supports a tentative contribution, but the untracked factors prevent an exclusive causal conclusion.

Key takeaways

Key takeaways

  • Identify what an answer silently asks you to add.
  • Do not infer motives, sole causes, or universal rules without evidence.
  • Preserve the passage's sample, setting, and time frame.
  • The most economical supported explanation usually wins.
