Can we make a contrapositive of the argument?
In the argument, (solving a paradox) -> A , B, or C. So the contrapositive of the sentence is A, B and C -> not (solving a paradox)
So I chose E...
Thank you, Dave.

You can always extrapolate the contrapositive of any conditional statement. Always.
But you do have to perform the operation correctly according to our unchanging, absolutely stable rules.
For the claim:
Solving → A or B or C
the correct contrapositive is formed in the same manner as always:
~A AND ~B AND ~C → ~Solve
Answer choice (C) says:
~A → ~Solve
Clearer?
