A company's two divisions performed with remarkable consistency over the past three years: in each of those years, the pharmaceuticals division has accounted for roughly 20 percent of dollar sales and 40 percent of profits, and the chemicals division for the balance.
Which of the following can properly be inferred regarding the past three years from the statement above?
(A) Total dollar sales for each of the company's divisions have remained roughly constant.
(B) The pharmaceuticals division has faced stiffer competition in its markets than has the chemicals division.
(C) The chemicals division has realized lower profits per dollar of sales than has the pharmaceuticals division.
(D) The product mix offered by each of the company's divisions has remained unchanged.

问题分析：问题分析的是归纳，正确答案不允许出现与原文无关的东西，我们来看选项，A说total dollar sales，这个内容原文没有提过，杀。
B是面对的竞争的问题，competition这个内容显然是与原文没关系，杀。
C说chemical division和pharmaceuticals division哪个利润高，原文提到过利润，没有出现明显无关的内容，留着。
D product mix这个内容原文没提，干掉。
E说高利润的产品占到销售的百分比，所占百分比这个内容与原文没关系，干掉。
