Strengthen & Weaken Arguments

Strengthen and weaken questions test your ability to evaluate how new information affects an existing argument. Your task is to identify which option makes the argument more convincing (strengthens) or less convincing (weakens).

Fundamental Principles

Strengthening an Argument

A statement strengthens an argument if it provides additional evidence, supports the assumption, or increases the likelihood that the conclusion is correct.

Weakening an Argument

A statement weakens an argument if it introduces evidence that challenges the assumption, reduces confidence in the conclusion, or presents an alternative explanation.

Supporting Evidence

Facts, statistics, examples, or expert opinions that make an argument more believable.

Essential Formulation Tips

  • Identify the conclusion before reading the options.
  • Find the assumption that connects the evidence to the conclusion.
  • Choose the option that directly affects the argument.
  • Ignore information that is true but irrelevant.

Shortcut Execution Techniques

  • Strengthen = Build confidence in the conclusion.
  • Weaken = Create doubt about the conclusion.
  • Focus on the logical gap between evidence and conclusion.
  • Alternative causes often weaken an argument.
