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.

It's not as analogous as one that presents "Y -> Z," but I'd be open to picking the answer you describe. It may very well be the most analogous if we don't get another answer that's exactly the same, but with "Y -> Z."
