The correct answer is <span>C. by describing technical aspects of the climb Hillary didn't mention in his account and how these made the climb a greater accomplishment.
He doesn't exactly present specific details from Hillary's account. He simply recounts the adventure from his own perspective, mentioning some technical aspects that had been unknown previously. But the main purpose of Norgay's account is to describe that the climb was great precisely because it was impossible to do it alone.</span>
He would benefit from seeing a live performance because he would be able to view the emotions in real time instead of just reading the words on the paper. Also, a live performance might help him hear lines he missed while reading. The actions will also be more clear. He needs the essay to be as clear as possible.
Well, for starters, preparing an outline for an essay test usually helps you think through what you want to cover when writing. It's almost exactly like starting with a stick figure when drawing.
Also, when you plan out what you want to write, it'll be easier, and faster to write. Not only that, but your point will be more clear to your audience if you plan out your essay, versus writing what comes to mind.
If you have a better essay, you're more than likely going to achieve a better grade.
Hope this helped!
