Hey Haewon!
To answer question 1, well...I think that although function questions can be asked in a variety of ways, they fundamentally ask you about the same thing: which answer best accomplishes the goal stated in the question stem? So, although the goal can change (i.e. best introduces the paragraph, provides the most similar example, best emphasizes the previous sentence), your approach to the question doesn't. You first carefully read the question (break it up into smaller parts, pause for a moment after reading the question so you clearly understand what it's asking, and/or paraphrase it if you need to to gain a fuller understanding). Then, if you clearly understand the question, you'll know what to do next. For example, in #38, I know that I need to understand what the given examples are discussing; then, I need to choose an answer that most closely matches those examples. The examples in the sentence are about minimal environmental impact. So, the answer that most closely matches that topic has to be (B)! =) It's that simple. The biggest mistake students make is they rush their understanding of the question. Don't make that mistake, and you will be fine!
2. For this question, the following information is the information after the comma; it is just the information that comes next. Sometimes that could be the next sentence, but in this case, since the underlined portion is part of one sentence, you need to consider the information after the comma (many of these schools offer concentrations such as conserving water...). What is this information "doing"? It is discussing the PROGRAMS the school offers. Which answer matches most closely to that topic? (A) - "interests in a specific area of sustainability" implies the courses that focus on specific areas of sustainability. (D) is stating "WHEN (time related information)" the school opened, which doesn't match the topic as directly as (A).
Hope this helps!
Keep moving forward!
You got this!
