Which three parts of these excerpts reflect the idea that war affects not only the minds of the combatants but also their physical reactions?

Ambush

by Tim O'Brien (excerpt)

There was no sound at all-none that I can remember. In a way, it seemed, he was part of the morning fog, or my own imagination, but there

was also the reality of what was happening in my stomach. I had already pulled the pin on a grenade. I had come up to a crouch. It was

entirely automatic. I did not hate the young man: I did not see him as the enemy, I did not ponder issues of morality or politics or military

duty. I crouched and kept my head low. I tried to swallow whatever was rising from my stomach, which tasted like lemonade, something

fruity and sour. I was terrified. There were no thoughts about killing. The grenade was to make him go away-Just evaporate--and I leaned

back and felt my mind go empty and then felt it fill up again.

Symptoms

by John Steinbeck (excerpt)

They would discuss their experiences right up to the time of battle and then suddenly they wouldn't talk anymore. This was considered heroic

in them. It was thought that they had seen or done was so horrible that they didn't want to bring it back to haunt them or their listeners. But

many of these men had no such consideration in any other field.

Only recently have I found what seems to be a reasonable explanation, and the answer is simple. They did not and do not remember and the

worse the battle was, the less they remember

In all kinds of combat the whole body is battered by emotion. The ductless glands pour their fluids into the system to make it able to stand up

to the great demand on it. Fear and ferocity are products of the same fluid.
