Answer :

Answer for the first box = It is not raining

Answer for the second box = I don't see lightning

The full contrapositive is "If it is not raining, then I don't see lightning".

==============================================================

Explanation:

Any conditional is of the form "If P, then Q". The P and Q are placeholders for logical statements.

To form the contrapositive, we do two things

  1. swap the positions of the P and Q terms
  2. negate each of the P and Q

Doing that has "If P, then Q" turn into "If not Q, then not P"

In this case,

  • P = I see lightning
  • Q = It is raining
