Please, answer me.

I don't understand why answer "there is no CHANCE of that" is wrong?
I don't see some diferent in those two answers?

Thank you

This means it is not at all possible.

Hey Alan, I`m a little confused you said it means it`s not at all possible, but I think that`s very different to say "there is no chance of that" this last in my opinion sentence tells me -there is no opportunity to get that- and the sentence you wrote tells me by the clue "not at all possible" there is still a hope to win, and the option i choose was "There is no promise of that" because it tells me "No one can assure you if the party is going to win"

Could you make this clear to me please?
