单选题 At the outset, Nixon warned, too, that a great effort would be needed to meet the Communist challenge. But his audiences seemed______in such warnings, preferring to be reassured.
【正确答案】 C
【答案解析】解析：C项uninterested意为“不感兴趣的，无利害关系的，无关系的”。根据空格处的意思“但是他的听众们似乎对此类警告不感兴趣”，故选C。A项interested“感兴趣的”；B项disinterested“公正无私的；无偏见的；客观的；漠不关心的”；D项interesting“有趣味的，引起好奇(或注意)的”，均不符合题意。
