Identify a question type that challenges the stability of an argument.

Weaken questions are specifically designed to challenge the strength and stability of an argument by introducing evidence or reasoning that undermines its conclusions. When faced with a weaken question, the task is to find an option that lessens the support for the argument's claims, making it less persuasive or valid.

These questions focus on identifying flaws or gaps within an argument, often exposing weaknesses in the logic or missing information that, if true, could negate the argument's validity. By undermining the argument's foundation, such questions encourage critical thinking and analysis, which is vital for evaluating the robustness of reasoning in any given argument.
