参考答案

正确答案：C
解析：词义题型见第二段第一句：But it is striking how much less talk there is about the poor than there was eight years ago，when the country was economically uncertain，or in previous eras，when the country felt flush．此句是拿现在与八年前及再早些的年代相比：八年前国家的经济变幻莫测(when the country was economically uncertain，)与再早些的年代国家经济flush相对，由此推断出flush应与uncertain意义相对，因此答案为C。
