A mixture of poems and short fiction, Jean Toomer’s Cane has been called one of the three best novels ever written by Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man.

A.Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

B.Black Americans—including Native Son by Richard Wright and Invisible Man by Ralph Ellison

C.a Black American—including Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

D.a Black American—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man

E.a Black American—the others being Richard Wright’s Native Son and Ralph Ellison’s Invisible Man


答案是选E，我选的是B   为什么是a Black American呢？答案D又错在什么地方呢？
请大家帮忙解答   多谢~

按照我的理解，三本美国黑人写的小说，看后面的句子每本都是只有一个作者，所以是a Black American,如果用Black Americans的话，就成了每本小说有多个作者。
为什么D错了呢，因为句子的主语是书的名字，D中后面引导的the others...的主语成了书的作者，就不对称了。
我做的时候也选错了。
要主要句子的逻辑，高分数段的语法题重逻辑而不只是简单的句子结构上的单复数对称。
