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.
Which of the following can be inferred as to the relationship between Ellison’s work and political movements of his time（） (A) It had a positive effect, establishing an incisive critical black voice in a time dominated by white literature.
(B) It contributed only a small positive effect, as it was not widely read by anyone outside the white literary establishment.
(C) Invisible Man served only a documentary function, as it chronicled a movement established long before the novel was published.
(D) Its ethereal and naive tone tended to underplay the seriousness of the movement.
(E) It tended, through verbosity and excess symbolism, to restrict the public’s perception of the basic effectiveness of the movement.
