The content provides an in-depth analysis of how to approach sufficient assumption questions on the GRE, focusing on identifying the conclusion, evaluating the evidence, and selecting the answer that fills the logical gap to guarantee the conclusion's validity.
  • Sufficient assumption questions require adding information to existing evidence to ensure a conclusion is undeniably true.
  • Identifying the conclusion and the evidence provided is the first step in solving these questions.
  • The gap between the evidence and the conclusion must be filled with an additional piece of information.
