(A)
Black Americans—the others being Richard Wright, author of Native Son, and Ralph Ellison, author of Invisible Man
This sentence gets it wrong in two key spots:
1. Black Americans should be singular. These are all classic works of literature that were each written by a single American - Jean Toomer, Richard Wright, and Ellison, not multiple black Americans
2. Violation of parallelism; the start of the list refers to the book Cane so the other two elements in the list should be Native Son and Invisible Man NOT Cane, Wright, and Ellison
(B)
Black Americans—including Native Son by Richard Wright and Invisible Man by Ralph Ellison
Corrects the second issue in A, but still has the first issue (in A).
(C) a Black American—including
Richard Wright, author of Native Son, and
Ralph Ellison, author of Invisible Man
C-E all get the plurality of Black American correct, but this one here still violates the parallelism error
(D) a Black American—the others being
Richard Wright, author of Native Son, and
Ralph Ellison, author of Invisible Man
Violates the parallelism error
(E) a Black American—the others being Richard Wright’s Native Son and Ralph Ellison’s Invisible Man Correct
Fixes both issues in A.
