Answer:
E. Intelligence and Intensity
Explanation:
The book mentions Walt's intensity and his intelligence. When Jon Krakauer goes to speak with Walt McCandless, he notes: "the set of his [Walt's] jaw betrays an undercurrent of nervous energy...there is no mistaking from whence Chris's intensity came". They also note several times at the intelligence of Mr. McCandless, and that of Chris is noted by several people throughout the book.

Answer: I don't know of the book you read, but..
Authors use historical times and revise them in such a way it's believable, immersive, and informative. They make sure their use of history isn't changed into an outlandish fashion to fit the time it's set in. They usually do this because you can't go back in history and show them what happened, so you must create a fictional yet historical piece to preserve the time.
