Answer;
If a character permanently changes as a result of the conflicts in the story, that character is Dynamic. 

Explanation;
A dynamic character is the person who changes over time, while a static character is someone who does not change overtime.
Protagonist is the central character in story who is trying to achieve something, while the antagonist is the character standing in the way of protagonist.

The answer to your question is DYNAMIC.

This is because a STATIC character does not change in the course of the story, and PROTAGONISTIC and ANTAGONISTIC are the types of characters.

The answer to the question above would be that the sentences in this excerpt from Ernest Hemingway's "In Another Country" that reflect the theme of the psychological alienation caused by war are the following ones: "We were all a little detached, and there was nothing that held us together except that we met every afternoon at the hospital". (...)"We felt held together by there being something that had happened that they, the people who disliked us, did not understand".

Alienation refers to a man being alone in a hostile universe all by himself. Nobody who has not gone through a war can understand how soldiers and civilians who have been in a war zone feel. Hemingway refers to the war as "something that had happened that they, the people who disliked us, did not understand".
