C is correct.    when you put A and D in this blank, the sentences do not make sense and  no meanings.

It is difficult for present-day readers       Sister Carrie was withdrawn from circulation at the turn of the century.

a. to understand the novel why         d. to understand why the novel

答案为ｄ，the novel　与　Sister Carrie　为同位语吗？yes.  可是ａ为何不对，ｗｈｙ引导的从句可以做定语从句修饰the novel吗？NO,

"understand why"  is a common expression.

The flowering of African American talent in literature, music, and art in the 1920’s in New York City became to know as the Harlem Renaissance.
