GRE五大难题之一（杨鹏语），我还是不理解杨鹏的解释

In Raisin in the Sun, Lorraine
　　Hansberry does not reject integration or
　　the economic and moral progress of the
　　American dream; rather, she remains
(5) loyal to this dream while looking,
　　realistically, at its incomplete
　　realization. Once we recognize this
　　dual vision, we can accept the play's
　　ironic nuances as deliberate social
(10) commentaries by Hansberry rather than
　　as the "unintentional" irony that Bigsby
　　attributes to the work. Indeed a
　　curiously persistent refusal to credit
　　Hansberry with a capacity for
(15) intentional irony has led some critics
　　to interpret the play's thematic
　　conflicts as mere confusion,
　　contradiction, or eclecticism. Isaacs,
　　for example, cannot easily reconcile
(20) Hansberry's intense concern for her race
　　with her ideal of human reconciliation.
　　But the play's complex view of Black
　　self-esteem and human solidarity as
　　compatible is no more "contradictory"
(25) than Du Bois' famous, well-considered
　　ideal of ethnic self-awareness
　　coexisting with human unity, or Fanon's
　　emphasis on an ideal internationalism
　　that also accommodates national
(30) identities and roles.

In which of the following does the author
of the passage reinforce his criticism
of responses such as Isaacs' to Raisin
in the Sun?
A.The statement that Hansberry is "loyal"
(line 5) to the American dream
B.The description of Hansberry's concern
for Black Americans as "intense" (line 20)
C.The assertion that Hansberry is concerned
with "human solidarity" (line 23)
D.The description of Du Bois' ideal as
"well-considered" (line 25)
E.The description of Fanon's internation-
alism as "ideal" (line 28)

如果没记错的话是选D。
楼主注意题干中的reinforce，有再次强调之意。
本文强调的评论criticism是Hans本来是有意使文章irony，但评论家Bigsby和Issac都认为他是没能力（或者说误打误撞？）。前文已经有Bigsby的评价[道理论证]，后面再次强调肯定是Issac的这部分，是通过比较Hans和Du Bois还有Fanon的作品。[对比论证]
对DB的作品的评价是well-considered，深思熟虑的，不正好是作者所一直强调的，irony是Hans有意为之的吗？

杨鹏还说了哪些是难题啊，我觉得最恶心的莫过于马斯洛还是马洛里的那篇文章了，从头到尾都“没一句人话”。
