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, (杂志广告)导致吸烟者变换品牌划不来，and that cigarette companies would have been no worse off economically if they had dropped their advertising.烟商如果不做广告也不会受到经济损失。

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）

(E) figures for the cigarette industry as a whole and may not hold for a particular company从行业整体获得的数据不能应用于个别企业。

此题选E，对着答案，我模糊理解：行业内部用户调换品牌，还是在本行业内，10%的广告费占收入依然还有10%的品牌变换者出现，所以划不来；但对于个别企业，如果不做广告，那么用户会被抢走，所以做广告拉拢客户还是划得来的。

问：1、关于原文的两句翻译对否？

2、偶理解的对否？

1，同意你的翻译。

2，偶得理解是：E说明：玉溪烟不做广告，中华烟做广告，10%的烟民从玉溪转向中华，没有烟民从中华转向玉溪。总的比率仍是10%。 ----〉广告是行业内互相之间的竞争。 和你的理解应该是一样的。
