当做饭或炒菜时，如果没油了，在其中添加少许醋和酒精，会收到意想不到的同样效果，这究竟是怎么回事？

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

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

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