For history class, ross has to write a research paper on an aspect of the 1960s. since he loves music, ross has narrowed down his topic to music of the 1960s. after completing some background research, ross decides to discuss the ways that classic rock music mirrored the new-found freedoms within society. a.1960s music is great. b.though it was popular then, no one listens to music from the 1960s now. c.classic rock emerged in the 1960s at the same time society rebelled aga

I believe you are asking which of these answer options is the most fitting thesis statement. If this is the case, then I believe option C is the best answer. Even though not all of it is available, Ross seems to be asserting that the music that was becoming popular in the 1960s reflected the freedoms that society was beginning to get. This would be a good research statement because it is neither too broad nor too narrow, and it summarizes the main argument of his paper in a succinct way. Hope this helps.
