Inference and Must-Be-True

Separate conclusions that are logically supported from statements that are merely plausible, familiar or likely.

Evidence set

Treat statements as given

Use only the information supplied and avoid importing outside assumptions.

Combine

Link compatible facts

Connect statements carefully when their terms and logical direction permit it.

Control

Match certainty

Select an answer no stronger than the support provided.

What to master

  • Must-be-true versus most-strongly-supported tasks.
  • Conditional chains.
  • Quantifier relationships.
  • Safe inferences from comparisons and categories.
  • Avoiding extreme or overgeneralized answer choices.

BoardQBank strategy

1

Summarize the facts without turning them into an argument.

2

Identify direct consequences before attempting complex combinations.

3

Test each answer against the possibility that the facts are true and the answer is false.

4

Prefer modest wording when the evidence is limited.

Practice focus

  • Conditional must-be-true questions.
  • Most-strongly-supported questions.
  • Inference questions involving groups, proportions and comparisons.
