Correct Answer: A
Explanation:
The passage describes the attitude of premodernized society toward war as accepted, even noble, and certainly necessary. Coupled with the goals of war in premodernized societies, we can infer that leaders of premodernized society regarded war as a valid policy tool. On this ground we select (A), eliminating (B) and (C). As for (D), although this can be inferred to have bee a feature of war in premodernized society, (D) does not respond to the question. What did the leaders think of war, that is, what was their attitude? (E) can be eliminated on the same ground and also because that “necessity” for war was not that described in (E).
