Premise 1: Winning - > Willingness to cooperate Premise 2: Willingness to cooperate - > Motivation
Conclusion: ~Motivated - > ~Win
Why? Take the contrapositive of the two premises:
Premise 1: ~Willingness to cooperate - > ~Winning Premise 2: ~Motivation - > ~Willingness to cooperate
And we can link those together to get
~Motivation - >~Willingness to cooperate - > ~Winning
Which get us ~Motivation - > ~Win, the diagram of the stimulus. To make the structure of the argument a bit more abstract, we can write:
A - >B B - >C Conclusion: ~C - >~A
As for the correct answer choice, we can see that when we diagram (C), we have:
Premise 1: Retain status - > Raises more money Premise 2: Raises more money - > Increased campaigning
Conclusion: ~Increased campaigning - > ~Retain status
And we can see that this matches the structure above, if A = retain status, B = raises more money, and C = increased campaigning. Keep in mind that we can diagram "X unless Y" as ~Y - >X, and we diagram "X only if Y" as X - >Y. "X requires Y" is diagrammed as X - >Y. Hope this helps!
