4. Which phrase or detail from the speech most clearly supports Reagan's idea that the Challenger crew members were important pioneers and explorers?

im sorry

Explanation:

the answer is c or the third one.

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.
