单选题 The government, when it places high duties on imported commodities of classes C and D,______.

A、 raises the price of commodities produced by A and B
B、 is, in effect, taxing the workers in A and B
C、 raises the wages of workers in C and D at the expense of the workers in A and B
D、 does not affect the productivity of the workers in A and B, although the wages of these workers are reduced

【正确答案】 B

【答案解析】[解析] 文章第三段最后两句提到，The government now renders this difficulty by placing high duties upon the former class of commodities．This means that workers in A and B must pay higher prices for what they buy，but do not receive higher prices for what they sell。由此可知，这种做法实际上是向优势行业工人收税，故[B]正确，同时可以排除[A]。[c]的内容出现在文章第四段第二句，但这并不是政府征收进口税的目的，政府征收进口税是为了使劣势行业产品在进口产品面前更具竞争力，故[C]错误；根据第62题的解析可知，劣势行业和优势行业工人工资是相同的，故[D]错误。
