Suppose the stimulus to a parallel reasoning question was something along the lines of:

A⊃B

B⊃C

C⊃D

A,

Therefore D.

And one of the answer choices read:

W⊃X

X⊃Y

~Z⊃~Y,

W,

Therefore Z.

The sentence '~Z⊃~Y' is the contrapositive of Y⊃Z, and so just as the first argument is valid, so too is the second. But I was wondering if, in a parallel reasoning question, they will ever give an answer choice that utilizes the contrapositive.

Sorry for my poor ability to formulate a question.
