TIM: When a rare tragedy, such as a plane crash, occurs, many people

The right answer is D. This is a structure based CR question, which means that we need NOT actually care whether the argument is valid or not. All we need to understand is what role Susan's point plays. In this case, she counters Tim by providing an alternative explanation for the cautious behaviour.

Option A - "makes apparent" suggests that Susan has successfully refuted Tim's argument, which is not the case, and also something we don't need to care about. She's merely providing an alternative explanation. OUT

Option B - This is actually the opposite of what Tim has argued. He's actually saying that just because an event happened before it DOESN'T mean that it will happen again. Hence, this gets the structure of the argument grossly wrong. OUT

Option C - Susan doesn't do this. If it were so, she would directly address what he said rather than provide a different line of reasoning. OUT

Option D - "presents an alternate basis" does the job perfectly. It demonstrates that Susan is simply providing a different line of reasoning, which is what she does in the argument. This works fine and is therefore CORRECT.

Option E - She disputes that the belief itself is unfounded with her alternate explanation, not the meaning of the term . OUT
