单项选择题
In some ways, Ralph Ellison’s protagonist in Invisible Man emblematizes what might be called the "presentist simplicity" of the novel’s endorsement of industrial, imperialist, xenophobic American myth-making. Layer upon layer of Line allusion mark its chapters, which in combination with the novel’s Homeric(5) ambitiousness, serve finally to obscure rather than to prophesy the actual, engaged, advanced-guard, public sphere effectiveness of American blacks already at work modernizing the United States. Simply stated, Ellison believed morality, equality, and responsibility were affirmative "notions", but blacks, at the very moment of Invisible Man’s glorious reception, were transforming(10) "notions" into decisively affirmative actions, by courageously putting body and soul on the line and constructing a sphere of American ethical publicity undreamed by the novelist. Ellison thus remained silent on the possibilities of an altogether "unexceptional" America-a post-industrial, radically black public sphere conditioned America.
It may be inferred from the passage that at the time Invisible Man was published, many blacks contributed more to American life than Ellison by（） (A) establishing and arguing for the implementation of social practices more affirmative than those found in Invisible Man
(B) eschewing the obligations that praise of Ellison’s work entailed for him, and thereby working to subvert the literary system
(C) supporting a vision of "exceptional" America in contrast to Ellison’s "unexceptional" version, and broadening the scope of that vision
(D) putting the same theories of reform Ellison espoused in his book into concrete practice through activism
(E) exposing the more effective critique of traditional American values advanced by Ellison’s literary precursors
