Surveys show that every year only 10 percent of cigarette smokers switch brands. Yet the manufacturers have been spending an amount equal to 10 percent of their gross receipts on cigarette promotion in magazines. It follows from these figures that inducing cigarette smokers to switch brands did not pay, and that cigarette companies would have been no worse off economically if they had dropped their advertising.
想請問一下這一篇到底再說什麼
真的很困惑
他說調查指出每年只有10PERCENT的吸煙者會換抽煙的牌子
但是製造商花了收入的10PERCENT在PROMOTION上
所以指出...接下來的地方我真的很模糊
他是說換牌子抽的人不用付??而菸商經濟方面不會變糟~??
煩請高手指教啊~感恩不盡

建議下次直接把整篇題目po齊喔, 這樣後續有問題的人也才好討論:)

調查指出每年只有10%的抽煙人口會換他牌香菸抽,
但, 香菸製造商卻花了相當於10%的毛利去做雜誌廣告;
以上的數據就代表了 用廣告去誘使抽菸的人換牌子是不會帶來額外營收的,
and that 把廣告撤掉也不會讓香菸公司的營收比較糟


我對這段的理解大致是這樣, 不是翻譯喔;
如有誤還請指正^^

It follows from these figures that inducing cigarette smokers to switch brands did not pay, and that cigarette companies would have been no worse off economically if they had dropped their advertising.
19.Of the following, the best criticism of the conclusion that inducing cigarette smokers to switch brands did not pay is that the conclusion is based on
(A) computing advertising costs as a percentage of gross receipts, not of overall costs
(B) past patterns of smoking and may not carry over to the future
(C) the assumption that each smoker is loyal to a single brand of cigarettes at any one time
(D) the assumption that each manufacturer produces only one brand of cigarettes
(E) figures for the cigarette industry as a whole and may not hold for a particular company
ans:E
我很不懂...要assumption嘛
跟E有什麼關係咧...a跟D都比E好不是嗎
