Which sentences in these excerpts reflect the common theme of soldiers’ reluctance to talk about their war experiences?
a) she knew about the war; she knew i'd been a soldier.

c) this is why i keep writing war stories
d) if they had been reticent men it would have been different, but some of them were talkers and some were even boasters
e) they would discuss their experiences right up to the time of battle and then suddenly they wouldn't talk anymore
f) only recently have i found what seems to be a reasonable explanation, and the answer is simple

First B) It was a difficult moment, but I did what seemed right, which was to say, "Of course not," and then to take her onto my lap and hold her for a while

This sentence and the soldier's response came after he was asked if he has killed someone. It is clearly evident from the words alone that he had a hard time talking about it, even though he claimed he didn't kill anyone. He just talked about it because he thinks "it seemed right"

Second E) They would discuss their experiences right up to the time of battle and then suddenly they wouldn't talk anymore

In this next sentence we can tell that the soldier has been comfortable narrating his experiences pre-war. After that, he just couldn't find himself going on for more. This would tell us specifically that they cannot find the courage to actually talk about the events that happened in the war itself.

b. both have yearned to escape the environment they experienced as a child.

specific audience will understand the main ideas. for example, if you were writing an instruction manual for rocket scientists, it would likely look very different from one you would write for young children. your language, tone, and writing style would change significantly.
