A “must be true” question is one that asks you to logically infer a statement from a set of facts. The question stem for a role of a statement question might read:

  • If the sentences above are true, then which of the following must be true?
  • The information above is true only if which of the following is true?
  • Which of the following must be true if the statements above are true?

We solve these questions by following two steps:

  1. Examine the fact pattern or argument.
  2. Choose the answer that can be logically inferred from the fact pattern or argument.

Let’s take a look at each step.

Examine the Fact Pattern or Argument

These fact patterns can sometimes be difficult to pay attention to, but a good understanding of the content in the stimulus is important. The solution here is to mentally paraphrase the material. Put it in your own words as you read. This will not only force you to pay attention; it will increase your ability to retain the information as well.

Choose the Answer

We want an answer that can logically inferred from the premises. It’s not enough to be strongly supported by the premises; we need a valid inference that must be true. This means that the negation test works here. If you negate the correct answer choice, it will contradict the fact pattern.
