"The Dream Comes True from The Tiger of the Snows" by Tenzing Norgay.
1. Why do you think Norgay is so concerned with the "prestige of Everest"?
A: I think Norgay is so concerned with the "prestige of Everest" because he thought it might be ruined by unchecked exploitation.
2. What does he mean by "Everest and the truth"?
A: I think Norgay was referring to Everest and the truth of which of the two hikers, Hillary and Norgay, reached its summit first.
I disagree with your first answer. Norgay wasn't thinking of exploitation. He felt that Everest deserved the truth, no matter what.
2. You're partly right. Norgay honors and respects Everest.
