CARS Logical Reasoning

Argument Structure

Arguments have premises (evidence) and conclusions (claims). Identify both.

Strengthening & Weakening

  • Strengthen: Evidence that supports the conclusion or fills a gap
  • Weaken: Evidence that undermines a premise or provides a counterexample
  • The answer must address the specific connection between evidence and conclusion

Assumptions

An assumption is an unstated premise the argument relies on.

  • Test by negation: If negating the choice destroys the argument, it's a necessary assumption

Common Fallacies

  • Ad hominem: Attacking the person, not the argument
  • Straw man: Misrepresenting an opponent's position
  • False dichotomy: Only two options when more exist
  • Appeal to authority: Citing authority rather than evidence
