og-115 b 答案

115. Many people argue that tobacco advertising plays a crucial role in causing teen-agers to start or continue smoking. In Norway, however, where there has been a ban on tobacco advertising since 1975, smoking is at least as prevalent among teen-agers as it is in countries that do not ban such advertising.


Which of the following statements draws the most reliable conclusion from the information above?


(A) Tobacco advertising cannot be the only factor that affects the prevalence of smoking among teen-agers.



(B) Advertising does not play a role in causing teen-agers to start or continue smoking.



(C) Banning tobacco advertising does not reduce the consumption of tobacco.



(D) More teen-agers smoke if they are not exposed to tobacco advertising than if they are.



(E) Most teen-agers who smoked in 1975 did not stop when the ban on tobacco advertising was implemented.


If tobacco advertising were the only factor that affected teenage smoking, there would be a difference in the


prevalence of smoking between countries that ban such advertising and those that do not. According to the



passage, there is no difference, so tobacco advertising cannot be the only factor. Therefore, choice A is the best



answer.Since no information is given about what effect, if any, the Norwegian ban on tobacco advertising had on



teenage smoking in Norway, none of choices B through E can be concluded, since each makes some claim



about the effects of tobacco advertising, or of banning such advertising, on teenage smoking or on tobacco consumption.


怎么理解b的解释啊?谢谢。

原文说从1975禁做烟广告后,N的青少年吸烟至少和别的国家一样普遍。比较点是和别的国家,不是和禁止做烟广告前,所以不知禁止做烟广告前的情况,即禁止做烟广告的EFFECT(效果)不知道。原文也不知道广告的效果。B,D说烟广告的效果,C,E说禁止做烟广告的效果。故错。原文说作广告的国家和不作广告的国家吸烟一样普遍,说明还有其他因素影响吸烟。故A对

to be my honestly speaking, it is so hard that I can't distinguish these kind of questions. because the difference among the 5 choices is so slight.....


especially A, B, C

斑竹解释的很清楚。但是从这点上去理解If tobacco advertising were the only factor that affected teenage smoking, there would be a difference in the prevalence of smoking between countries that ban such advertising and those that do not. According to the passage, there is no difference, so tobacco advertising cannot be the only factor. Therefore, choice A is the best answer 我就不明白og中A选项的解释,显然ets排除了挪威比其他国家在1975前可能 prevalence更广。
