The word 'paramount' (Paragraph 4) may be replaced by ______.
A.vital
B.more important
C.less important
D.similar

A.A.vital
B.more
B.less

【参考答案】

A
解析：这是一道词义题。题干中的信号词出自于文章第四段第四句话中。文章第四段指出：由于人口更多，工资更低，发展中国家将集中发展劳动密集型产业；相反，更富裕的国家可以发展多种高新技术产业，这些产业中，高生产率、专业化知识是极为重要的；其结果将是提高全球所有国家的生产率，导致人民的生活水平更高。这说明，该单词最可能的意思应该是“极为重要的”。A说“至关重要的”，这与文章的意思相符。该单词所在的句子并不是在比较，所以B不对；C与文章的意思相反；D不准确。

There are probably no questions we can think up that can't be answered, sooner or later, including even the matter of consciousness; to be sure, there may well be questions we can't think up, ever, and therefore limits to the reach of human intellect, but that is another matter.
