Explanation:

This is the detail that is least supportive of the main idea. In the main idea, the author states that wind power is becoming an increasingly popular source of renewable energy in the United States. Options A, B and D give examples of how we can know that this is the case. However, option C, although it deals with the topic of wind power, discusses only what the case is in other countries, which does not give the reader useful information that supports the main idea.

since it is asking for her reaction to elnora's trouble at school you can rule out any answers with a positive response (b). then you can rule out (d), this is because it does not show the mother's reaction but the daughter's response. that leaves you with two options (a) and (c), by looking at the options you can rule out (c) because it isn't referring back to elnora's issues at school.
