Why E is the correct answer ? The argument doesn't talk about any other method to electing a president. But considering the details we have we can surely infer that number of votes received was not a criterion. So shouldn't D be the correct answer ?
If votes received was the only criterion for being elected, why wouldn't Tom have been elected instead? This means that there had to have been some other criterion, hence why it's E. You can argue that maybe there was a recall and people voted again but the question asks what can we conclude based on the
information above.
Why isn't it D? D states that votes received was not a criterion, at all. The first red alarm should be that it's an extreme answer, saying that it can't be true. Looking deeper into it, maybe votes received was a criteria but maybe you only needed to get 30% of the votes (which both Tom and Jim received) or maybe it's a criteria that has a small part in determining who will become president. Therefore, since it's possible that D isn't true, it's incorrect.
I was interested in A so I'll go over why I concluded it's wrong. A is incorrect because, simply, maybe there were 4 candidates but that last one didn't receive any votes.
