The author refers to James Fenimore Cooper and Willa Cather in order to suggestLet's look at the context in the passage:
Quote:
The dime-store Western never aspired to be anything but entertainment. James Fenimore Cooper and Willa Cather, however, used themes of westward expansion in works clearly intended as highbrow literature.
The word however introduces a turning point. In the first line the author has indication entertainment as lowbrow. So, he means that
dime-store Western is lowbrow. On the other hand, he regards Cooper's and Cather's works as highbrow.
A. that their works are examples of entertaining literature - Opposite is true.
B. that their literary achievements were no less impressive than those of McMurtry - Irrelevant.
C. that the themes of the Western genre could be employed in literature meant to appeal to a more sophisticated reader - highbrow would appeal to a sophisticated reader. Isn't so? True.
D. that they were contemporaries of McMurtry - This is may answer what, not why.
E. that the theme of westward expansion was a multicultural concept - Again, irrelevant.
Hence, C is the correct answer.
