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.
不明白为什么是C。。。
一点想法：
文中说：the pharmaceutical division is growing stronger 因为 it contributed 45 percent of the corporation’s profits, up from 20 percent the previous year.
主要evaluate: it contributed 45 percent of the corporation’s profits, up from 20 percent the previous year.
(A) The increase in the pharmaceutical division’s contribution to corporation profits could have resulted largely from the introduction of single, important new product. 与比例无关
(B) In multidivisional corporations that have pharmaceutical divisions, over half of the corporation’s profits usually come from the pharmaceuticals. 涉及 其它--无关
(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. 对应原文-traditionally contributed。
(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. 无关--讲去年的20%(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. 无关
不理解
(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.
原文中没有提及performance啊？ 何谓performance? 何谓improve performance？
再，兄弟缘何evaluate这题？ 不是critique吗？
(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.
C is correct for the following reason:
The original arguement: The profit of the pharmaceutical division has inproved from last year because its profit share has improved compared with that of the chemical division . (please pay attention, this arguement is a concise summary of the whole paragraph)
C is correct because it points out the logical mistake the officer makes. He thinks that profit and profit share are the same, when actually they are not.
谢谢mbz！你说的profit share没错
但是我看原文只说：the pharmaceutical division is growing stronger
他并没有说The profit of the pharmaceutical division has inproved
而我觉得 profit share的确可以证明growing stronger啊，请再指点！
the pharmaceutical division is growing stronger: it contributed 45 percent of the corporation’s profits, up from 20 percent the previous year.
==> the profit share is up
don't forget his background information: the chemical division is down.
Choice C says, Heh, even if the pharmaceutical division profit has not improved, its profit share can still be up.
我有点明白了，但是和你说的好像也不一样：
这里critique的是 the ph is growing stronger.
C说， even if its performance(=profit) was not improved, the profit share也会增加；也就是说他们根本没变强； 如其中可能的原因就是其他部门profit share的下降
对不？
也就是说他们根本没变强； 如其中可能的原因就是其他部门profit share的下降
对不？
you've got it.
这个题的前提和结论要先清楚.
前提是Corporate Officer 的话;结论在therefore 后面;题目要求找出作者的Evidence的问题,指的是20%和45%的关系;而60%只是文中的background.
