: ※ 引述《scont ( )》之銘言：
: : 75. (33198-!-item-!-188;#058&007254)
: : In the year following an eight-cent increase in the federal tax on a pack of

我想問一下，D的解釋是消費者的收入在稅提高後，比在稅提高之前還要少
而購買力下降，這樣的話不就加強了嗎??因為稅提高的關係而影響到銷售量
我一直繞不出來阿 @@ 請強者幫幫忙感謝~~
: : 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.

: : 我想問一下 題目主要不是在討論稅跟銷量的關係嗎?為什麼會跟危害健康有關?
: : 感謝回答~
: 該題要問的是strengthen
: b選項講的是消費者不論是在稅增加前或增加後，所能得到的、關於抽菸會導致健康風險

: 換句話說，會影響銷售量的不是其他的原因(資訊)，而是題目所說的增稅的關係
: 所以strengthen該題主旨
