单选题 With its publication in 1885, the Concord Public Library banned the book for "being more suited to the slums than to intelligent, respectable people". ______ , Clemens relished the ban and happily told his publisher the controversy would generate 25,000 in sales copies.
A. Unattended B. Unbiased C. Undeterred D. Unbalanced

【正确答案】 C

【答案解析】[解析] C选项：Undeterred意为“未受阻的，未被吓住的”，如：It was raining heavily，but he set out undeterred．(雨下得很大，他仍不顾一切出发了。)句意：该书于1885年出版，康科德公共图书馆禁止该书发行，理由是它更适合给贫民窟的人看，而不适于有知识的、值得尊敬的人。克莱门斯并没有知难而退，他对这个禁令没有感到沮丧，反而高兴地告诉他的出版商，这场争论会产生25000册的销量。故选C。
其他三项：Unattended无人陪伴的；Unbiased无偏见的；Unbalanced不平衡的。
