How do "weaken" questions differ from "strengthen" questions?

The key difference between "weaken" questions and "strengthen" questions lies in their objectives regarding the argument being presented. Weaken questions specifically aim to find evidence or information that would diminish the credibility or the validity of the argument. This means that they focus on uncovering flaws or challenges to the conclusion that the argument draws.

On the other hand, strengthen questions are designed to bolster or support the argument. They require identifying evidence that reinforces the argument's conclusion, making it stronger or more sound. By analyzing the established claims or premises, strengthen questions look for additional support that validates the argument rather than undermines it.

The correct response highlights these objectives: weaken questions are about finding evidence that diminishes or undermines the argument, while strengthen questions aim to find evidence that supports or enhances it. This distinction is crucial in understanding how to approach different types of questions in logical reasoning on the LSAT, as each type has a different impact on the validity of the argument presented.
