75.    (33198-!-item-!-188;#058&007254)

 

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.

 

请问d选项为什么不行呢

我是这样想: 因为烟的税增加
                所以烟的价钱变贵
                所得就相对减少
                购买力下降所以比较不会去买烟
                买烟的数量下降

推理思路：税上升，导致烟的价钱上升，导致销量减少。要加强的是，加税后的烟价上升导致销量减少。

A. During the second year after the tax increase, cigarette sales increased by a significant amount.  加税后的烟价上升导致销量上升了。削弱（同因异果）

B. The information available to consumers on the health risks of smoking remained largely unchanged in the period before and after the tax increase.  消费者们得到的信息没变，排除他因。加强。

C. Most consumers were unaware that the tax on cigarettes was going to increase.  无关。管你有没有意识到。

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.  给出他因。消费者的钱少了，买烟买得少了，所以销量下降。削弱。

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.  无关。

lZ清楚了吗？D是削弱。不是加强。

谢LS 这道题也正好是我想问的

谢谢回答

所以d选项是不是我误会了?

D选项是说
            消费者所得减少是因为通膨的关系
            而刚好又发生在cigarette tax increase期间
        这样对嘛
             我之前一直把它想成税上升
        因此所得”相对”减少
