I think that the element of the story that is least related tot he author's biographical story is the C. SMELL OF MILDEW IN A VIETNAMESE VILLAGE.
Tim O'brien wrote the story using his personal experiences. He was sent to Vietnam in his tour of duty. He's familiar with the geography of the Vietnamese coastline, he vividly describes the climate and landscape, and he feels the fear that the soldier felt during wartime.
Iambic pentameter is considered a more refined and eloquent way of speaking where as prose/ blank verse shows a very common or uneducated way of speech.
