All students who are members of the debate team are excellent writers. Sarah is an excellent writer.
Which of the following conclusions can be validly drawn from these statements?
Correct: B
The original statement translates to: Debate Team Members -> Excellent Writers. We know Sarah is an excellent writer, but that doesn't guarantee she's on the debate team. However, if she *wasn't* an excellent writer, she definitely couldn't be on the debate team. This is the contrapositive of the original statement and is logically valid. The contrapositive of A -> B is ~B -> ~A (If not B, then not A). Option B is correct.
