OG-45

OG-45好象还没有问过。。。

45.

The tobacco industry is still profitable and projections are that it will remain so. In the United States this year, the total amount of tobacco sold by tobacco-farmers has increased, even though the number of adults who smoke has decreased.

Each of the following, if true, could explain the simultaneous increase in tobacco sales and decrease in the number of adults who smoke EXCEPT:

A. During this year, the number of women who have begun to smoke is greater than the number of men who have quit smoking

B. The number of teen-age children who have begun to smoke this year is greater than the number of adults who have quit smoking during the same period

C. During this year, the number of nonsmokers who have begun to use chewing tobacco or snuff is greater than the number of people who have quit smoking

D. The people who have continued to smoke consume more tobacco per person than they did in the past

E. More of the cigarettes made in the United States this year were exported to other countries than was the case last year.

45.

If the number of men beginning to smoke and the number of women quitting smoking during the year are equal, A would result in an increase, not a decrease, in the number of adults who smoke. Hence, A does NOT explain the facts cited and is the best answer.

Given the decrease in the number of adults who smoke, the increase in tobacco sales could be explained by a proportionally greater increase in the non-adults who smoke or the nonsmokers who use tobacco. An increase in total tobacco use by smokers or in the sales in the United States tobacco abroad would also explain the facts cited. Thus, because B, C, D and E could explain the facts cited, none of them can be the best answer.

偶想问C选项为什么不能选呢？偶觉得它好象和A选项是一个道道。。。谢谢。

文中说的是所有吸烟的成年人总数下降了。而A中说的是开始吸烟的女性大于戒烟的男性，如果开始吸烟的男性等于戒烟的女性，那么吸烟的成年人的总量是上升的而非下降。

A的问题在于将吸烟的人群分类，但只考虑了其中的一类人。而C将吸烟的人和不吸烟的人比较，这两类人组成一个完整的样本，即一个高，另一个一定低。

正确答案是A啊

偶感觉C也很像答案。。。

C说今年开始嚼烟或者用鼻烟的人比停止抽烟的人多，当然可以解释啦。

嚼烟或者用鼻烟的人和吸烟者不是一回事？

偶就琢磨着八成不是一回事，但又不敢肯定，谢谢！

甭管嚼还是鼻烟，总之是消耗烟多了就可以啊

偶的问题和lz一样，越看越觉得a和c是一个东东～～～

a）During this year, the number of women who have begun to smoke is greater than the number of men who have quit smoking

说女人开始吸烟的人比男人戒烟的人多

c）During this year, the number of nonsmokers who have begun to use chewing tobacco or snuff is greater than the number of people who have quit smoking

以前不吸烟的人比戒烟的人多

这里，以前不吸烟的人和以前不吸烟的女人有什么区别？

难道the number of nonsmokers 里有可能包括未成年人?

而the number of women 就一定是指成年女人？

后后～～～“成年女人”这个说法有点怪哈～～

但是如果C选项中，可能出现一种情况，就是 the number of nonsmokers who begin to smoke is greater than the number of smokers who quit smoking，那么即使the number of nonsmokers who have begun to use chewing tobacco or snuff is greater than
the number of people who have quit smoking,也会使总的吸烟人数增加呀。

C还是不能解释呀
