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
- swap the positions of the P and Q terms
- 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
