Since there is no video explanation from Chris on this question, I will try to explain this question and I will be really gald if I help figure out anyone's confusion. First to rewrite the question:
Because they had expected the spacecraft Voyager 2 to be able to gather data only about the planets Jpiter and Satrun, scientists were ______ the wealth of information it sent back from Neptune twelve years after leaving earth.
I think the clue is the first part of the sentence: Because they had expected the spacecraft Voyager 2 to be able to gather data only about the planets Jpiter and Satrun. This means this spacecraft was initially designed for gathering data only from two planets, but actually it did better than what scientists had expected. It received a wealth of information sent back from Neptune. So what's your response if you get 330 on your GRE, in which case you just reckon you may only get 323? You'll absolutely be "happy and surprise".
So we come up with our own words for the blank, which is " happy and surprise". If we look at the answer choices, (C) and (D) provide similar meaning to our own words. So the answers are (C) and (D).
That's almost right, Hugo! You're thinking along the right lines here. Choice (C), "thrilled about" is correct. However, the best match for (C) is choice (E), which is "elated by." Both "thrilled by" and "elated by" mean that someone is extremely happy about something. However, while "keen on" (choice D) also refers to liking something, it doesn't mean being extremely happy. So the right answers are C and E.
