Logic Breakdown

Passage Summary: Rhonda will only go to a movie if Paul goes to a concert. Paul will only go if Ted goes. Since Ted isn't going, the whole plan falls apart for everyone.

Conclusion: Rhonda will not be attending the movie tomorrow afternoon.

Reasoning: Rhonda's attendance depends on Paul going to a concert, and Paul's attendance depends on Ted going, but Ted has refused to go.

Analysis: This argument utilizes a 'chain of necessity' structure, often represented in formal logic as A → B and B → C. The argument then establishes that the final requirement (C) is false, which triggers a series of 'if-then' reversals (modus tollens) to prove that the first event (A) cannot happen. To find the parallel, look for a choice that sets up a similar conditional chain and then denies the final condition to disprove the initial one. The logic is perfectly valid, so we are simply matching the structural blueprint.

The pattern of reasoning displayed above is most closely paralleled in which one of the following?

Correct Answer
B
B mirrors the structure: G → P; P → C; ¬C; therefore ¬G. It uses “only if” and “unless” correctly and concludes by contrapositive across the chain, just like the stimulus.
