Fran is doing an indirect proof with four given statements and one conclusion. How many of these statements must be false based on her assumption to contradict the assumption and prove the original conclusion?

If you assume that the conclusion is false, and you find a contradiction, then the only thing left to say is that the conclusion is true

So let's assume that the conclusion is false. If this assumption is made, and it leads to making one of the given statements to be false, then we run into a contradiction (since the given statements are taken to be true)
