Answer:
The correct answer to the question: Which sentence should be revised to eliminate redundancy, would be, Sentence 3.
Explanation:
The reason for this being the sentence that needs to be removed because it is adding redundant information to the paragraph is that in both sentence 3 and sentence 4 the same information is being relied. Both sentences clarify that there will be a lot of histories, and stories, that will be talked about because they will be meeting with friends at their high school reunion. However, given the tone of the previous sentences, 1 and especially 2, which is a tone of excitement, from the two remaining sentence, the one that maintains the tone is number 4, so sentence number 3 is unnecessary and can be removed. The reason for sentence 2 not being the answer is that this sentence does not give the same information, but rather, explains what is said in sentence 1. Just because they are going to a high school reunion, doesn´t mean they are meeting with friends, and thus these two sentences could be taken as redundant. Rather, sentence 2 expands on what sentence 1 has already established. And sentence 4 explains further what will happen during that meeting with friends.
