I'm going to assume that this is from Tim O'Brian's "The Things They Carried." The thing that stood out the most for me in this chapter was that some of the most horrible things can't be talked about, because those who don't experience it won't believe that such a horrible thing can happen. I also found it interesting and fairly accurate when they say that happening-truth isn't as true as story-truth. This struck me because it shows that feelings can sometime be shown only by exasperation or imagination. It also shows that feelings are true and not to be put aside when telling a story.
The answers are "early, and tomorrow." Adverbs are words that makes the sentence understandable or able to be modified. Modification could include the verb, the adjective, could even be a another adverb, etc... anything that would be able to make the sentence better.
