Posted this as a comment under the Problem Set, but am really unsure of why my reasoning is incorrect so looking for help. Won't add the question here so it doesn't act as a spoiler but I've referenced the question in the post title.
I've pasted my comment below:
"My only qualm with the elimination of E is that if there's a possibility for an earthquake to never happen, or happen less frequently, is that not safer than one that just occurred, but won't for another 99,999 years? I've tried to show my thinking with the comparison below:
Nuclear site 1: 1 earthquake every 10 million years, last occurred 1 million years ago (definitely before living memory).
Nuclear site 2: 1 earthquake every 100,000 years, last occurred yesterday.
Even if an earthquake just occurred at Nuclear site 2, the next one would still occur before the next one at Nuclear site 1. In this case, it would not be safer to build at Nuclear Site 2, even if an earthquake just occurred at site 1?
I understand why C is necessary, but given the reasoning above, don't see how to rule out AC E."

Hey! I'm interested as well.
