Answer:

#2^25#

Explanation:

If it were only one question, there would be #2 = 2^1# F-T alternatives, and thus, answer keys.

If there were 2 questions, there would be #2^1 times 2^1 = 2^2# alternatives.

If you are comfortable with that line of argument, you see that for 25 questions it grows rapidly to #2^25#.
