In the past, every ten-percentage-point increase in cigarette prices in the country of Coponia has decreased per capita sales of cigarettes by four percent.  Coponia is about to raise taxes on cigarettes by 9 cents per pack.  The average price of cigarettes in Coponia is and has been for more than a year 90 cents per pack.  So the tax hike stands an excellent chance of reducing per capita sales of cigarettes by four percent.

Which of the following is an assumption on which the argument depends?

A.      Tobacco companies are unlikely to reduce their profit per pack of cigarettes to avoid an increase in the cost per pack to consumers in Coponia.

B.       Previous increases in cigarette prices in Coponia have generally been due to increases in taxes on cigarettes.

C.      Any decrease in per capita sales of cigarettes in Coponia will result mainly from an increase in the number of people who quit smoking entirely.

D.      At present, the price of a pack of cigarettes in Coponia includes taxes that amount to less than ten percent of the total selling price.

E.       The number of people in Coponia who smoke cigarettes has remained relatively constant for the past several years.

以前的帖子都是讨论a和e，选a应该是对的，但是我想不通d错哪儿了呢

d说现在的价格是包含了少于10％的税的，把d取否，就是没包含税。如果没包含税，则烟民现在要付的价格比90分钱高，那么9分钱就不到10％，也就不会有sales下降了，所以d听起来也对啊

难道取否的重点应该在低于10％上？请nn们不吝赐教啦

就是不是这样的话对文章也没有影响啊，任何条件下只要减少了税就可能导致最后销售两结果的变化，所以这个是不影响最后结论的
