Infer carefully from the text · LSAT Reasoning

9 min + practice · Original foundation lesson

A supported inference follows from the passage without importing an attractive outside claim.

Recognize the distinction

A reading inference can combine statements without repeating them verbatim, but it must respect the author's qualifications. Distinguish what the author states, what the author implies, and what would merely be plausible in the real world. Subject knowledge is useful for comprehension but cannot override the evidence supplied in the passage.

Choose a method

Locate the relevant lines, paraphrase their relation, and test whether the proposed inference could be false while those lines remain true. Strong words demand strong support. An author who values pilot studies for feasibility has not said that every pilot proves effectiveness or that effectiveness is irrelevant. A qualified claim often supports a similarly qualified inference.

Worked contrast

In the forest-carbon passage, current uptake rate and stored carbon are different quantities. It follows that a high uptake rate alone does not settle the effect of replacing an old forest. The passage does not say that young forests cannot absorb carbon. That opposite overstatement is not rescued by the author's criticism of a particular policy argument.

Transfer and check

For transfer, mark each answer as stated, supported, contradicted, or not established. Explain why a choice in the last category could be true in reality yet remain unjustified here. This habit prevents answers based on familiarity with a topic rather than the author's actual reasoning.

WORKED EXAMPLE

Original foundation reading selection (shorter than a full official passage): A pilot study is often asked to do two jobs: show that a procedure can be carried out and show that it works. These jobs require different kinds of evidence. A small pilot can reveal that participants misunderstand instructions or that equipment frequently fails. It will usually provide much less certainty about a modest treatment effect, because outcomes vary even when no treatment is given. Calling a pilot inconclusive about effectiveness need not dismiss it as a failure. It may have answered a practical question that must be resolved before a larger trial can be informative. Which statement is most strongly supported by the selection?

  1. The relevant detail is: A pilot can reveal confusing instructions or unreliable equipment.
  2. A study can succeed at its feasibility objective while leaving a treatment-effect question open.
  3. This inference preserves the author's qualifications without importing a universal or opposite claim.
Answer: A study can succeed at its feasibility objective while leaving a treatment-effect question open.
Compare the other answer choices
Every small pilot can determine precisely whether a treatment works.

This stronger generalization is not established by the text.

A pilot that leaves effectiveness uncertain necessarily produces no useful knowledge.

This is incompatible with an explicit distinction or claim in the text.

The author argues that larger trials never need reliable procedures.

This misstates what the author accepts or rejects.

The passage establishes the opposite of this claim: a study can succeed at its feasibility objective while leaving a treatment-effect question open.

The passage supports the stated inference rather than its opposite.

Try it, then explain it.

Complete a short set without looking at the example. After each answer, explain which evidence or rule supports your decision and why the alternatives do not fit.
