单选题 It can be inferred from the passage that the author would______.

D、 contend that manipulation of the size of the labor force would have prevented recessions in the years noted

【正确答案】 A

【答案解析】推理判断题。根据文章倒数第二段：高失业率并不是科技发展的必然结果，而是消极的公共政策所造成的。在文章最后，作者还提出要采取积极的政策，说明作者并不喜欢高失业率，并且认为高失业率是可以控制的。故选项A是正确答案。其它选项与原文内容相悖，均不是答案。
