Bar Course Aptitude Test (BCAT) Inference flashcards — 52 questions with answers

  1. In the Watson Glaser sense, what is an 'inference'?

    A conclusion a person draws from observed or supposed facts. It is a proposition that may be true or false to varying degrees, based only on what the passage states or strongly implies, not a directly stated fact.

  2. In the Watson Glaser Inference test, on what basis must you judge each proposed inference?

    Solely on the information given in the passage (plus common, universally accepted knowledge), treating the passage as true. You must not use specialist or outside knowledge or your own opinions.

  3. List the five response options on the Watson Glaser Inference response scale, in order from most to least supported.

    True (T), Probably True (PT), Insufficient Data (ID), Probably False (PF), and False (F).

  4. On the Watson Glaser five-point scale, what does the response 'True' (T) mean?

    The inference is definitely true; it follows beyond reasonable doubt from the facts given in the passage.

  5. On the Watson Glaser five-point scale, what does 'Probably True' (PT) mean?

    In light of the facts given, the inference is more likely to be true than false; the passage gives some support but not conclusive proof.

  6. On the Watson Glaser five-point scale, what does 'Insufficient Data' (ID) mean?

    You cannot tell from the facts given whether the inference is true or false; the passage neither supports nor contradicts it on balance.

  7. On the Watson Glaser five-point scale, what does 'Probably False' (PF) mean?

    In light of the facts given, the inference is more likely to be false than true; the passage gives some evidence against it but does not conclusively disprove it.

  8. On the Watson Glaser five-point scale, what does 'False' (F) mean?

    The inference is definitely false; it is directly contradicted by, or misrepresents, the facts given in the passage.

  9. What is the single most important rule when answering Watson Glaser Inference items?

    Reason only from the passage. Assume every statement in the passage is true, and do not import any outside knowledge, assumptions, or personal beliefs.

  10. Why must you treat the passage as true even if it contradicts what you know about the real world?

    The test measures inference from given premises, not factual recall. Judging against reality instead of the stated facts is a classic error that leads to wrong answers.

  11. What is the conceptual difference between a 'True' and a 'Probably True' inference?

    'True' is conclusively established by the passage with no room for doubt; 'Probably True' is only made more likely than not by the passage, leaving genuine possibility it is false.

  12. What is the conceptual difference between 'False' and 'Probably False'?

    'False' is directly contradicted or definitively ruled out by the passage; 'Probably False' is merely made more likely to be false than true, without being conclusively disproven.

  13. When should you choose 'Insufficient Data' rather than 'Probably True' or 'Probably False'?

    When the passage gives no evidence that tips the balance either way, so you genuinely cannot say the inference is more likely true or more likely false.

  14. What kind of evidence justifies a 'True' rather than 'Probably True' rating?

    The inference must be logically entailed by, or explicitly restated from, the passage so that it cannot be false if the passage is true.

  15. A passage says 'All members of the committee voted in favour.' Inference: 'Every committee member supported the motion.' What is the correct rating?

    True (T). The inference is logically equivalent to a directly stated fact in the passage.

  16. A passage states 'It rained heavily all day on Tuesday.' Inference: 'The outdoor match on Tuesday was cancelled.' What is the correct rating, and why?

    Insufficient Data (ID). Heavy rain makes cancellation plausible but the passage never states a match occurred or was cancelled, so you cannot judge it.

  17. A passage states '90% of surveyed students passed the exam.' Inference: 'Most surveyed students passed.' What is the correct rating?

    True (T). 'Most' means more than half, and 90% conclusively satisfies that, so it follows directly from the figure given.

  18. A passage states '90% of surveyed students passed.' Inference: 'A student chosen at random from the survey definitely passed.' What is the correct rating?

    Probably False (PF) or False depending on phrasing of 'definitely'. Since 10% failed, it is not certain any given student passed; the claim of certainty is unsupported, making it more likely false than true.

  19. Why is 'Probably True' often the correct answer when a passage gives a strong statistical majority?

    A majority makes a single-case or general claim more likely than not but not certain, which matches the definition of 'Probably True' rather than 'True'.

  20. What is a 'common probability misjudgement' that test-takers make with figures like '70% favoured X'?

    Treating a high-but-incomplete proportion as a certainty (rating 'True') instead of recognising the remaining minority, which usually makes the correct answer 'Probably True'.

  1. A passage says 'Some of the new employees attended the training.' Inference: 'At least one new employee attended the training.' Rating?

    True (T). In logic 'some' means 'at least one', so the inference is directly entailed.

  2. A passage says 'Some of the new employees attended the training.' Inference: 'Some new employees did not attend the training.' Rating?

    Insufficient Data (ID). 'Some attended' does not tell you whether the rest attended or not; 'some' is consistent with 'all'.

  3. Why is reading scope/quantity words like 'all', 'some', 'most', 'none', 'few' so important in inference items?

    These words fix the logical strength of a claim. Misreading 'some' as 'most', or 'all' as 'some', changes whether an inference is True, Probably True, or Insufficient Data.

  4. What does the quantifier 'most' mean precisely in inference reasoning?

    More than half (a strict majority), i.e. greater than $50\%$. It does not mean 'nearly all' or guarantee any specific higher proportion.

  5. What does 'few' typically imply, and how can it trap test-takers?

    'Few' implies a small number, usually a minority. Treating 'few attended' as 'none attended' or as 'many attended' both misread its scope and lead to errors.

  6. What is 'overstating support', and why is it a common inference error?

    Rating an inference 'True' when the passage only makes it likely, or 'False' when the passage only makes it unlikely. It overstates how strongly the evidence backs the claim, when 'Probably True'/'Probably False' is correct.

  7. What is 'importing real-world knowledge', and why is it penalised in Watson Glaser Inference items?

    Using outside facts, expertise, or assumptions not in the passage to judge an inference. It is penalised because the test requires reasoning strictly from the given text.

  8. A passage about a fictional country states 'Country Z has no coastline.' Inference: 'Country Z has major seaports.' Rating?

    False (F). The passage states there is no coastline, which directly contradicts having seaports, regardless of any real-world country named Z.

  9. You personally know a fact that contradicts the passage. How should this affect your inference rating?

    It should not affect it at all. You must reason as if the passage is true and ignore contradicting outside knowledge.

  10. What three-step process is recommended for tackling a Watson Glaser Inference item?

    1) Read the passage and accept it as true; 2) Read the proposed inference; 3) Decide how strongly the passage alone supports or contradicts it, then map that strength onto the five-point scale.

  11. When an inference goes beyond the passage but is not contradicted by it, which rating is usually correct?

    Insufficient Data (ID), unless the passage provides indirect evidence making it more likely true or false (then PT or PF).

  12. A passage says 'The library is open from 9am to 5pm on weekdays.' Inference: 'The library is closed on Sunday.' Rating?

    Insufficient Data (ID). The passage only mentions weekday hours and says nothing about Sunday, so its weekend status is unknown.

  13. A passage says 'The library is open from 9am to 5pm on weekdays.' Inference: 'The library is open at 6pm on a Monday.' Rating?

    False (F). Monday is a weekday and the stated hours end at 5pm, so being open at 6pm is contradicted.

  14. Why can the same factual passage yield 'True' for one inference and 'Insufficient Data' for another almost-identical one?

    Because small differences in scope, time, or wording change whether the passage actually entails the claim. Inference rating depends on exact logical fit, not general topic.

  15. What self-correction question should you ask before marking an inference 'True'?

    'Could this inference be false while every statement in the passage is still true?' If yes, it cannot be 'True'; it is at most 'Probably True'.

  16. What self-correction question should you ask before marking an inference 'False'?

    'Could this inference be true while the passage is still true?' If yes, it cannot be 'False'; it is at most 'Probably False' or Insufficient Data.

  17. How do you distinguish 'Insufficient Data' from 'Probably False'?

    Choose 'Probably False' only if the passage contains some evidence tilting against the inference. If there is genuinely no evidence either way, choose 'Insufficient Data'.

  18. A passage states 'Sales rose every year from 2010 to 2020.' Inference: 'Sales rose in 2021.' Rating?

    Probably True (PT) at most, or Insufficient Data. A consistent past trend makes continuation plausible but does not guarantee it; many graders treat it as ID since 2021 is outside the stated period.

  19. A passage states 'Sales rose every year from 2010 to 2020.' Inference: 'Sales in 2015 were higher than in 2014.' Rating?

    True (T). The passage states sales rose every year in that span, which directly entails the 2014-to-2015 increase.

  20. What is the danger of inferences that contain absolute words like 'always', 'never', 'all', or 'definitely'?

    They demand conclusive support. Unless the passage establishes the absolute claim completely, such inferences are usually only 'Probably True' or are 'Insufficient Data'/'False'.

  21. Why might a plausible, sensible inference still be rated 'Insufficient Data'?

    Because plausibility from general experience is not evidence from the passage. If the text itself gives no supporting facts, the correct rating is 'Insufficient Data'.

  22. A passage says 'Dr. Lee published more papers than any other researcher in the department.' Inference: 'Dr. Lee is the best researcher in the department.' Rating?

    Probably False (PF) or Insufficient Data. Quantity of papers does not establish quality or 'best'; this imports an unwarranted value judgement, so it is not supported.

  23. What is the comparison between 'Probably True' and 'Insufficient Data' in terms of evidence balance?

    'Probably True' means the passage's evidence tips the balance toward truth (more likely true than false); 'Insufficient Data' means the evidence does not tip the balance at all.

  24. If a passage strongly suggests but does not state an outcome, and nothing contradicts it, which two ratings are you choosing between?

    'Probably True' versus 'Insufficient Data', depending on whether the suggestion is strong enough to make truth more likely than not.

  25. A passage says 'No member of the choir can read sheet music.' Inference: 'The choir's tenor, John, can read sheet music.' Rating?

    False (F), provided John is a choir member. 'No member can' directly contradicts any individual member being able to.

  26. What is the key risk of 'misreading scope' with the word 'only'?

    'Only X' restricts a claim to X and excludes others. Overlooking 'only' can make you accept inferences about excluded cases that the passage actually rules out.

  27. In Watson Glaser Inference, how should you treat an inference that merely restates a fact explicitly given in the passage?

    Rate it 'True' (T), since a direct restatement of a given fact is conclusively supported.

  28. Summarise the decision rule mapping evidence strength to the five ratings.

    Conclusively supported = True; tilted toward truth = Probably True; balanced/no evidence = Insufficient Data; tilted toward falsity = Probably False; conclusively contradicted = False.

  29. Why is 'the passage doesn't mention it, so it's False' a flawed reasoning pattern?

    Absence of mention is not contradiction. Lack of information supports 'Insufficient Data', not 'False'; 'False' requires the passage to actively contradict the inference.

  30. A passage says '60% of voters supported the proposal; the rest opposed it.' Inference: 'A majority of voters supported the proposal.' Rating?

    True (T). $60\% > 50\%$ is a majority, and the figure is given directly, so the inference is conclusively supported.

  31. A passage says '60% of voters supported the proposal.' Inference: 'Nearly all voters supported the proposal.' Rating?

    Probably False (PF) or False. 'Nearly all' overstates a $60\%$ majority; $40\%$ opposed, so the strong claim is not supported and is more likely false.

  32. What final self-check should you run across an entire Inference test before submitting?

    Confirm that each answer used only passage facts, that you did not confuse 'some/most/all' scope, and that you did not over-rate likely claims as certain ('True'/'False') when 'Probably' or 'Insufficient Data' fits better.
