10. Advertisers are often criticized for their unscrupulous manipulation of people’s tastes and wants. There is evidence, however, that some advertisers are motivated by moral as well as financial considerations. A particular publication decided to change its image from being a family newspaper to concentrating on sex and violence, thus appealing to a different readership. Some advertisers withdrew their advertisements from the publication, and this must have been because they morally disapproved of publishing salacious material.

(B) Some advertisers switched from family newspapers to advertise in the changed publication.

(C) The advertisers expected their product sales to increase if they stayed with the changed publication, but to decrease if they withdrew.

(D) People who generally read family newspapers are not likely to buy newspapers that concentrate on sex and violence.

(E) It was expected that the changed publication would appeal principally to those in a different income group.

以下是引用concong在2004-11-15 11:54:00的发言：

广告商退出在一份有性和暴力的杂志登广告---〉有些广告商在做广告时是由道德标准的。

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

(A) The advertisers switched their advertisements to other family newspapers.

广告商转到一个家庭报纸去了。（和推论没有关系。我们不知道他们是由于什么原因转的，A没有提到）

(B) Some advertisers switched from family newspapers to advertise in the changed publication.

这个明显会削弱推论的。

(C) The advertisers expected their product sales to increase if they stayed with the changed publication, but to decrease if they withdrew.

广告上如果还继续在那个会有性和暴力内容的杂志作广告，他们的产品销售会增长，如果退出，他们的产品销售会减少。（这个就告诉我们为什么广告商有钱不赚？因为道德的原因，他们不愿意在性和暴力的杂志做广告，所以是答案）

(D) People who generally read family newspapers are not likely to buy newspapers that concentrate on sex and violence.

这个还是说明广告商退出是由于经济因素的考虑，而不是道德因素。

(E) It was expected that the changed publication would appeal principally to those in a different income group.
