Answer:
"It burns the prettiest of any wood" is a phrase that, through allegory, focuses on the concept of equality, by establishing that everything that has the same characteristics will ultimately have the same result, since the intrinsic equal nature of things means that, despite minor differences, this difference is not seen in the essence of the thing. Thus, all those things that are essentially the same, such as wood, beyond their minor characteristics (beauty, for example) are equal to each other and therefore will burn in the same way.
If your options are: A) One day I had said that Italian seemed such an easy language to me that I could not take a great interest in it; everything was so easy to say. "Ah, yes," the major said. B) 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. C) We were all a little detached, and there was nothing that held us together except that we met every afternoon at the hospital. D) It was warm, standing in front of her charcoal fire, and the chestnuts were warm afterward in your pocket. E) <span>The major, who had been a great fencer, did not believe in bravery, and spent much time while we sat in the machines correcting my grammar.
The correct answer is A, in my opinion. It doesn't talk about apathy (the loss of interest and psychological indifference to everything). It shows apathy in a dialogue between two people, thus proving that apathy has infused every single aspect of the soldiers' lives in Milan. The major's short answer "Ah, yes" also shows it. The two people talk about their lack of interest for Italian, and they are not even interested in this talk that they have.</span>
