Question

Indirect Proof Help? Stuck between last 2 choices

What is the assumption needed to begin an indirect proof of the following statement?
"A team is as strong as its weakest member."


A. A team is as strong as its weakest member.
B. A team is as strong as its strongest member.
C. A team is not as strong as its weakest member.
D. A team is not as strong as its strongest member.

Answer 1

D. A team is not as strong as its strongest member. Answer C is a double-negative, if you say that "A team is as strong as its weakest member." Then you can not say "A team is not as strong as its weakest member." Because then it would contradict the statement since it is the reversal of the statement.
