Common Question Types

Meet the LSAT Logical Reasoning Questions

The LSAT tests your ability to analyze arguments using a variety of question types. Each tests a different logical skill, so knowing what to expect is half the battle!

Key Question Types

  • Assumption: What must be true for the argument to work?
  • Flaw: What’s wrong with the reasoning?
  • Strengthen/Weaken: What would make the argument stronger or weaker?
  • Inference: What can you logically deduce?
  • Principle: What general rule applies?

How to Approach Each

For each type, look for clues in the prompt and focus on what the question is really asking.

Why This Matters

Recognizing question types quickly lets you choose the best strategy for answering, saving time and boosting accuracy.

Everyday Applications

These skills help you spot when someone is making a shaky claim, or when you need to ask, “But what if that’s not true?”

Examples

  • 'Which of the following, if true, most seriously weakens the argument above?' (Weaken question)

  • 'The argument assumes which one of the following?' (Assumption question)
