PrepTest 73, Logical Reasoning 1, Question 10

The essence of tackling sufficient assumption questions on the GRE involves identifying a piece of evidence that fills all gaps in the argument, thereby guaranteeing the conclusion's truth.
  • Sufficient assumption questions require a new piece of evidence that ensures the argument's conclusion is valid.
  • Identifying the conclusion and the evidence provided is crucial before finding the gap that needs to be filled.
  • Formal logic can be instrumental in bridging the gap between the evidence and the conclusion.
  • The correct answer must not only fill the gap but also guarantee the conclusion's truth without leaving room for doubt.
  • Analyzing each answer choice methodically to determine whether it fills the identified gap is essential.
