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.

1. Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man
2. Black Americans—including Native Son by Richard Wright and Invisible Man by Ralph Ellison
3. a Black American—including Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man
4. a Black American—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man
5. a Black American—the others being Richard Wright’s Native Son and Ralph Ellison’s Invisible Man

三本最棒的小说，分别有三个美国黑人写的。

怎么能用“a Black American”呢？

因此，排除C/D/E

A，个人觉得one……the others 用法不妥。具体还在总结中。

B is the best.

B我觉得用分词including在这里不妥，用分词一般逻辑主语应该是主句的主语，

在这里显然不成立

五月十三说三个美国人写的所以用americans，我觉得正确，如果这样我认为选A，one, the others在这里我觉得就相当于one ... the other two.
