Correct answer criteria

  • Something that, if true, would make the conclusion more likely to follow from the premises.

Key tactics

  • Identify the conclusion and the premises
  • Think about why the conclusion doesn't have to be true even if the premises are true
  • Pay attention to new concepts brought up on the conclusion but not mentioned in the stimulus. The argument has to make some kind of assumption about those new ideas
  • Be ready for arguments where the author tries to provide a hypothesis (causal explanation) for some phenomenon. If you see this structure, think about alternate hypotheses
  • Be open-minded. It's hard to predict exactly what the correct answer will involve

Answer choice tips

  • The correct answer doesn't need to 100% prove the conclusion. Even if it just makes the conclusion slightly more likely to follow from the premises, it can still be considered a strengthen answer. If multiple answers appear to strengthen, choose the answer that most strengthens (the answer that requires the fewest, and most reasonable assumptions)
  • If the argument involves correlation to cause or explanations for a phenomenon, be ready for a correct answer that is about eliminating an alternate explanation. This isn't always the correct answer, but it's common on this kind of argument
