大全III-18

Corporate Officer: Last year was an unusually poor one for our chemical division, which has traditionally contributed about 60 percent of the corporation’s profits. It is therefore encouraging that there is the following evidence that the pharmaceutical division is growing stronger: it contributed 45 percent of the corporation’s profits, up from 20 percent the previous year.

On the basis of the facts stated, which of the following is the best critique of the evidence presented above?

(A) The increase in the pharmaceutical division’s contribution to corporation profits could have resulted largely from the introduction of single, important new product.

(B) In multidivisional corporations that have pharmaceutical divisions, over half of the corporation’s profits usually come from the pharmaceuticals.

(C) The percentage of the corporation’s profits attributable to the pharmaceutical division could have increased even if that division’s performance had not improved.

(D) The information cited does not make it possible to determine whether the 20 percent share of profits cited was itself an improvement over the year before.（C）

(E) The information cited does not make it possible to compare the performance of the chemical and pharmaceutical divisions in of the percent of total profits attributable to each.

搜了关于这题的讨论,可是还是觉得不懂. 做题的时候我一直在C D E答案里面徘徊. 这是我的分析.麻烦NN帮我看看错在哪里.

c选项支持critique. 没意见: P部门的份额增长 即使自己表现不好 也可能来自总的profit的减少.也可能来自C和别的部门的份额减少所致.

d选项 仔细看发现我题目看错了. 选项是分析20%份额(P在过去的份额), 这和P与C现在的份额的讨论是无关的. 我原来看成P从过去到现在的增长为20%, 则D正确, 因为如果P增长20%, 他的份额增长可能来自自己的市场表现, 也可能来自别的部门(C和别的)的份额减少, 还可能来自总的prifit的减少, 同C选项.

e选项 我分析如下.

过去: P 20%, C 60% 其它部门20%

现在: P: 45%, C 未知. 其他部门: 未知 (C+其他部门=55%).   E选项说不能确定P和C各自的份额...好像是对的啊...

请NN解释下.
