OEThe final portion of this sentence describes
“studying the differences and similarities” between two different things. This implies you’ll be doing some sort of comparison, so a good fill-in word would be compare. Aggregate, agglomerate, and glean are an incorrect triple, all meaning
“gather.” While gathering the data together is required in order to make a comparison, the sentence already said
“not only to collect.” All of these words are just fancy versions of
“collect,” which you don’t need to repeat.
Deduce, which means
“to arrive at a conclusion logically,” doesn’t match any other choice. In addition, it doesn’t quite fit the context: you can reason logically about the score reports, but you wouldn’t reason the score reports themselves.
