Answer: I believe it would be letter (b)
Explanation: I had to answer this question yesterday and I am pretty sure this is the answer. Because it asks ¨the narrator gives an example of why oxygen is vital to climbers on Mt. Everest.

Because D doesn't really dislike dirt, he doesn't feel that it's important to wash it off. This is showing how he is indifferent to the customs of his culture. Most people would wash themselves, but he doesn't really see why that's so important so he doesn't. </span>
I believe your answers would be A, C, E.
Hope this helps. I didn't do much to research it. Tell me if I'm correct.
