s2008m [1.1K]

The options attached to the above question are given below:

A) The boys at first were very polite about my medals and asked me what I had done to get them.

B) I showed them the papers which were written in very beautiful language of full of fratellanza and abnegazione but which really said with the adjectives removed that I had been given the medals because I was an American.

C) after that their manner change a little toward me although I was their friend against Outsiders

D) I was afraid but I was never really one of them after they had read the citation because it had been different with them and they had done very different things to get their medals.

E) I had been wounded it was true but we all knew being wounded after all was really an accident.

ANSWER

The correct option is D.

In the statement given in option D, it can be seen that the speaker was formerly a soldier, who had fought in a war and had been awarded a medal to that effect. But despite knowing about this meritorious service that he had rendered to his country and the award he was given, he was not really accepted as an inner person by the group of people that was refereed to in the statement. They did not think much of him.
