Which one of the following, if true, most seriously weakens the reasoning above?

Assumption
Cannot Be True
Weaken
Parallel

The correct answer is: Weaken

The argument in the passage is based on the assumption that there is a correlation between two variables - success in school and success in life. The conclusion drawn is that academic success guarantees success in life. In order to weaken this argument, we need to find a statement that undermines the connection between academic success and success in life. Choice C, which is the correct answer, does exactly that by suggesting that some successful people did not perform well in school, thus weakening the assumption made in the argument. Options A, B, and D are not relevant to weakening the reasoning in the passage. Option A refers to assumptions, which are the basis of the argument and not necessarily contradictory. Option B discusses what cannot be true, which is not relevant for weakening the argument. Option D talks about parallel reasoning, which is not connected to undermining the original argument.
