I think that the sentences that portray a common theme of reluctance of soldier in telling their war stories would be letters B, E, and F. Letter B's statement gave it away with the word 'difficult'. Letter E's idea was concretely evident in the phrase 'suddenly they wouldn't talk anymore', and Letter F seems like it talks about why soldier's don't talk much about their experiences.
Metaphor, because it is comparing fame to a bee, without using like or as.
Hope this helped.
With good WORD CHOICE, the writer creates a mental picture for the reader by using words that are specific and accurate. The writer uses strong action verbs whenever possible to show the reader what is happening rather than tell the reader.
