Correct answer criteria

  • 100% proven by the information in the stimulus. The correct answer should not require any assumptions in order to be proven by the stimulus.

Key tactics

  • Take statements in the stimulus as true
  • There is no need to identify conclusions and premises
  • If there are any statements that can be connected to each other, try to connect them

Answer choice tips

  • Be careful about picking extreme answers (e.g., "All..." "Every..." "always"). Although strong answers can be OK, particularly if the stimulus is conditional-based, you should double-check to make sure they are truly supported
  • Weak answers (e.g., "Sometimes..." "possibly" "not always") are more likely to be correct than strong answers, since they are easier to support
  • Answers introducing concepts not discussed in the stimulus are highly unlikely to be correct
