SAT Inferences Practice: Questions and Answers

Practice SAT inference questions with three original passages. Draw conclusions from stated evidence, preserve uncertainty and check every distractor.

The short answer

An inference is a conclusion supported by the passage even when the author does not state it in the answer’s exact words. Identify the relevant facts, connect them with the smallest necessary reasoning step, and avoid adding motives or outside assumptions. Pay attention to uncertainty: a tentative result should not become a certainty. These original passages practice drawing a supported conclusion, interpreting qualified language and recognizing what a comparison cannot isolate. The correct answer should require less speculation than the alternatives.

Step-by-step method

Use these steps in order, then apply them to the questions below.

  1. Step 1: Collect the relevant facts

    Find the sentences that bear on the question. Keep quantities, qualifications and conditions attached to those facts.

  2. Step 2: Make a small reasoning step

    State what follows directly from the facts. Do not fill gaps with a story about what probably happened.

  3. Step 3: Preserve certainty

    Match words such as may, suggests and tentative. Reject an answer that turns a limited conclusion into an absolute one.

  4. Step 4: Test the alternatives

    Ask what extra assumption each choice needs. Prefer the choice supported by the passage rather than by outside knowledge.

Question 1 of 3

Original passage

A fictional community garden offered 18 plots during its first registration period. Forty residents requested a plot, and organizers created a waiting list for applicants who could not be assigned one.

Which conclusion is most strongly supported?

Choose an answer for question 1
View worked answer for question 1

Correct answer

Choice B: Initial demand for plots exceeded the number available.

Explanation

Forty requests for 18 plots establish that requests exceeded the available supply. The waiting list is consistent with that mismatch. The passage does not identify crops, gardening experience or a plan to close the garden, so those conclusions require unsupported information.

Why each choice is right or wrong

  1. Choice A

    The passage gives no information about applicants’ crop choices.

  2. Choice B

    Correct answer

    The 40 requests exceed the 18 available plots, directly supporting this conclusion.

  3. Choice C

    No experience requirement or waiting-list composition is described.

  4. Choice D

    Creating a waiting list does not establish an intention to close the garden.

Question 2 of 3

Original passage

In a fictional report, an analyst describes a proposed classification as tentative. The report says that additional observations may require some items to be moved into different categories.

What does the passage most strongly suggest about the classification?

Choose an answer for question 2
View worked answer for question 2

Correct answer

Choice A: It may be revised when further evidence becomes available.

Explanation

Tentative means the classification is provisional, and the possibility of moving items after additional observations supplies a specific way it could change. The supported inference is that new evidence may lead to revision. Caution does not imply deliberate deception, permanent certainty or complete uselessness.

Why each choice is right or wrong

  1. Choice A

    Correct answer

    This follows from the tentative label and the stated possibility of future category changes.

  2. Choice B

    Nothing in the report indicates dishonest intent.

  3. Choice C

    Permanent correctness conflicts with both tentative wording and possible revision.

  4. Choice D

    The passage allows revision but does not say the classification has no current use.

Question 3 of 3

Original passage

In a fictional classroom demonstration, one set of seedlings grew indoors under a lamp and another grew outdoors in natural light. The sets also received different watering schedules. At the end, the sets had different average heights. The class had not separately tested either light or watering.

Which conclusion is best supported?

Choose an answer for question 3
View worked answer for question 3

Correct answer

Choice D: The comparison alone does not establish whether light or watering explains the height difference.

Explanation

Both light conditions and watering schedules differed, and neither factor was isolated. The reported height difference therefore cannot be assigned to one of those factors from this comparison alone. The passage does not rule out watering or identify different species. The inference concerns the comparison’s limitation, not a new explanation of the result.

Why each choice is right or wrong

  1. Choice A

    The changed watering schedule prevents isolating light as the sole cause from this comparison.

  2. Choice B

    The passage provides no evidence that watering never affects growth.

  3. Choice C

    No species difference is stated or required by the information.

  4. Choice D

    Correct answer

    Because two conditions changed together, the comparison cannot separate their possible effects.

Common mistakes

  • Choosing a plausible story without textual support: identify the actual evidence for each claim.

  • Turning caution into failure or deception: a tentative result can still be useful.

  • Attributing an effect to one cause when several conditions changed: note what the comparison cannot separate.

Common questions

Is an inference just a guess?

No. It must follow from the provided information. A guess may be plausible, but a supported inference has a clear evidence chain in the text.

Should an inference answer repeat the passage exactly?

It may restate or connect facts in different words. The key is support, not identical wording. It still cannot introduce new motives, causes or conditions.

Why are absolute answers often risky?

Words such as always, never and definitely require strong support. A passage using tentative or may usually does not establish an absolute conclusion.
