id say at most 4 can be true; it the final is the contradiction then youve reached the point where its false .....

at any stage of teh game, if its false, we go false ... is my thoughts

Answer 16

at most four
========
Because the first statement in an indirect proof is to assume the negation of the theorem to be proved, then one statement IS false by design. That means that if there are N statements (excluding conclusion) in the indirect proof, at most (N - 1) will be true.
