求助一道og题

糊香肠

76. A famous singer recently won a lawsuit against an advertising firm for using another singer in a commercial to evoke the famous singer’s well-known rendition of a certain song. As a result of the lawsuit, advertising firms will stop using imitators in commercials. Therefore, advertising costs will rise, since famous singers’ services cost more than those of their imitators.

The conclusion above is based on which of the following assumptions?
(A) Most people are unable to distinguish a famous singer’s rendition of a song from a good imitator’s rendition of the same song.
(B) Commercials using famous singers are usually more effective than commercials using imitators of famous singers.
(C) The original versions of some well-known songs are unavailable for use in commercials.
(D) Advertising firms will continue to use imitators to mimic the physical mannerisms of famous singers.
(E) The advertising industry will use well-known renditions of songs in commercials.

我选的B，觉得因为歌手有用，所以公司才会用歌手，用了歌手花费才会高，所以是假设，不知道是咋回事，同志们帮个忙哈~

E还是很明显的
否定E，广告公司不用那个名人的歌曲了，自然就不用付钱给那个名人了，那么至少成本就不会上涨了。
B延展的过多，注意MORE EFFECTIVE，
即使否定B，否定的也只是MORE EFFECTIVE，NOT MORE EFFECTIVE中有一种情况是THE SAME EFFECTIVE，那么这种情况下依然会费用上涨，也就是说即使否定B，依然可以支持结论。
