Answer:
Hi! Unfortunately, your answer is incomplete since you didn't mention which text are you referring to. With so little information I can't even find anything worthy on the Internet, anyways, I'll try to guide you to give the correct answer yourself.
Step-by-step explanation:
The first thing you have to do is to carefully read paragraph three because the question is based on the information given there. So, read it carefully again. What you have to figure out is why GAINS are so important in the cause the text refers to. Apparently, as it says in the task, GAINS are super important, you have to find in the third paragraph the reason for these gains to be so important. Analize if its important is related with the relationship with USAID (A), or if it is related with economic support (B), maybe it is related with being an extension of the USAID (C), or with the quality of information GAINS have (D). Pick the option that best fits according to what you've read and you'll do great!
