Summary
The essence of the content revolves around dissecting a specific LSAT question type, focusing on how to approach and solve strengthen questions which are pivotal in supporting the arguments presented.
  • Strengthen questions necessitate bolstering the argument's unstated assumptions for the evidence provided to substantiate its conclusion.
  • The example provided illustrates a causal argument regarding the genetic adaptation of salmon species in Lake Clearwater, highlighting the importance of identifying assumptions inherent in causal arguments.
  • Key assumptions for causal arguments include the absence of alternate causes, the direction of the cause-effect relationship, and the non-coincidental nature of the change.
  • Analyzing answer choices involves eliminating options that do not support the argument's assumptions or introduce irrelevant or contradictory information.
  • The correct answer choice effectively eliminates an alternate cause, thereby strengthening the causal argument presented.
