Hey MatloccerSha,
I would have to say that the answer is answer choice 2, because 1 and 3 simply don't cut it when defining a thesis statement. For the first choice, a thesis statement and research for it should be most often focused on one topic. For the third choice, a thesis is used all throughout the process of creating of an essay. A proper thesis statement should do a good job of summarizing what your essay is about. Hope this helped.
Even though option D is also related to Modernism and could be related to the excerpt, option C seems to be the correct one: It conveys the idea of isolation from modern life.
Modernist were called "the lost generation" because of their search for meaning among the fragments of modern life. In the excerpt, the words "lonely men" seem to address the theme of isolation and alienation in society. While everyone seems to have a role to perform in modern life, that does not mean they have found their true identity. Some sort of value seems to have been lost and, with it, men lost themselves. Modernism is characterized by the search of such value.
The right answer for the question that is being asked and shown above is that: "Knights and crusaders are the theme and the historical setting The Middle Ages is the geographical setting." Nora read a story about an artist who lived in France during the time of knights and crusades. This is the true statement.
