请教大牛牛一道pre逻辑，死活想不明白阿

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.In contrast, in the year prior to the tax increase, sales had fallen one percent.The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

Which of the following, if true, would most strengthen the argument above?

A. During the second year after the tax increase, cigarette sales increased by a significant amount.

B. The information available to consumers on the health risks of smoking remained largely unchanged in the period before and after the tax increase.

C. Most consumers were unaware that the tax on cigarettes was going to increase.

D. During the year following the cigarette tax increase, many consumers had less income, in inflation-adjusted dollars, than they had had in the previous year.

E. During the year after the tax increase, there was a greater variety of cigarettes on the market than there had been during the previous year.

答案是B, 但我觉得这个选项跟题目一点关系都没有啊~

看了好多牛牛写的逻辑做题经验和原则，可是还是不开窍，痛苦万分，唉，马上就要考了，一点起色都没有。

本人的感觉,做加强题有两种思路,一种是架桥,所谓架桥就是题目中说的两个事物有一定的差别,所以在选项中要给出这两个事物的联系,一般会用same 等词.

第二种就是本题这种形式,排除他因.题目中说税涨了,销售掉了.而税涨之前,销售掉的少,所以推测税与销售有关系. B 选项, 对于消费者的信息没有变化,说明销售变化的时候,这个因素没有变化,也就是说不会是因为消费者的信息的原因导致的销售变化,排除他因. 所以B 正确.

…………靠“逻辑经验”来答题啊？？？？这能考好吗？

a.想必你不会选吧，就不解释了。
b.销量的下降原因多种多样，b排除了一个因素，这不就是在强化论据吗，怎么没关系呢？
c.无关
d.弱化
e.无关
