"If not-B, then not-A" is correct. Where it differs from the driving/movies question is the first answer, "If B, then A," which is not correct. (One question has an "only if", the other merely "if". So it's possible that the next batter hit a home run, for example, or that she hit a double and the next batter hit a triple, or the other team was caught cheating and had to forfeit, or something.)
Of course, the real fun is applying this analysis to political speeches. If one's blood pressure can stand it.
