comparison questions can get real tricky, but this is quite an easy question, if you know what to look for and use POE.GHong14 wrote:
The word "unlike" is a comparative - when you see it, check out what the sentence compares, and ask yourself whether these are two things that can logically be compared to each other.
The overall construction of the sentence is "Unlike X, Y", with X and Y being the two things that are compared.
Here, we have "Ross Perot's Run for presidency" after the comma, which means that whatever we compare must be something that can logically be compared to a "run". This automatically eliminates A, B, C, and D, all of which begin with "people" - either "George Wallace and John Anderson" (in A, B, C) or "the independent candidates" (D) - and people cannot logically eb compared to an inanimate "run". Only E correctly compares inanimate "candidacies" to "a run on for presidency" - we can choose E without even bothering to read the rest of the answer choices, or indeed E itself.
