Answer:
The evidence for Paul's reaction is:
1. People have no idea what happens in the war.
2. People worry about super-nice things while the war is going on.
3. He matured a lot and hard, while in military training and on the battlefield.
Explanation:
Paul used to identify with the people of his homeland, since he lives with them and shared very similar experiences, however, when he was called up for military service and taken to the battlefield he found himself in a very difficult reality to deal with. He had to mature very, very quickly to maintain his sanity in such an inhospitable environment. This caused him to lose all connection with the people of his homeland and to no longer be able to see them with importance, because they seemed superfluous.
Before answering the question, I would like to present the different modes of persuasion, also referred to as ethical strategies or rhetorical appeals. They are maneuvers in rhetoric that classify the speaker's appeal to the audience. The Rhetorical Appeals are:
Ethos: It is how well the presenter convinces the audience that the presenter is qualified to speak on the subject, and by doing that what the presenter says is valid.
Pathos: is an appeal to the audience’s emotions
Logos: it. It is normally used to describe facts and figures that support the speaker's claims or thesis.
Kairos: An orator uses this to their advantage to persuade the audience to act now at the time being.
Even though you did not include the excerpt, I know for sure you mean this one:
<em>"She had told them about the place where they would stay, promising warmth and good food, holding these things out to them as an incentive to keep going."</em>
In this particular case the rhetoric appeal used is:
an appeal to the audience’s wants and needs which is a Pathos Rhetorical appeal.
