OG-45 请帮帮忙 谢谢

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.

A is the best answer.

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.

想请教前辈们荧光部分的解释，不是很懂？谢谢！！

如果在这一年中开始抽烟的男性人数与戒烟的女性人数相等，选项A将导致成人烟民的人数增加，而不是降低。

偶不明白E跟这题目有什么关系，为什么E说出口增加了，就可以导致increase，支持题目问题呢/

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.

---不明白上面说“ E could explain the facts cited, n”，这个应该无关把

choice E  could explain the simultaneous increase in tobacco sales

部分解释也算是解释
