Identify parallelism in the short story "in another country" by citing textual evidence. how does the use of parallelism affect the story?

First we must understand that parallelism is using elements in sentences that are grammatically similar or identical in structure, meaning, sound, or meter. It adds symmetry, balance, and effectiveness. One example would be the following:

“We were all at the hospital every afternoon, and there were different ways of walking across the town through the dusk to the hospital”

I hope it helps, Regards.

Here are some examples from Hemingway’s "In Another Country" that demonstrate parallelism:

The hospital was very old and very beautiful.

In this first example, the word very before the word old and again before the word beautiful helps maintain the balance of the sentence.

The girls at the Cova were very patriotic, and I found that the most patriotic people in Italy were the café girls—and I believe they are still patriotic.

The word patriotism is repeated three times in this example. Patriotism is one of the important themes of the story.

The three with the medals were like hunting-hawks; and I was not a hawk, although I might seem a hawk to those who had never hunted.

Finally, the word hawk is repeated three times to emphasize how different the speaker was from the other boys. This repetition emphasizes the alienation that the speaker felt in Milan.
