题目

The more viewers a television show attracts, the greater the advertising revenue the show generates. The television network Vidnet's most popular show, Starlight, currently earns the network's highest profits, but next year because of unavoidable increases in production costs, its profits are projected to fall to below the average for vidnet shows.Therefore vidnet would earn greater profits overall if it replaced starlight with a show of average popularity and production costs.


Which of the following if true most seriously weakens the argument?

选项

A.

The average profits of Vidnet shows have increased in each of the last three years.

B.

Shows that occupy time slots immediately before and after very popular shows tend to have far more viewers that they otherwise would.

C.

Starlight currently has the highest production costs of all Vidnet shows.

D.

Last year Vidnet lost money on a weekly show that was substantially similar to Starlight and was broadcast on a different day from Starlight.

E.

Even if, as a result of increased production costs, Starlight becomes less profitable than the average for vidnet shows, it will still be more profitable than the average for television shows of all networks combine.


解析

一个电视节目吸引的观众越多,该节目产生的广告收入就越高。电视网络Vidnet最受欢迎的节目《星光》目前为该网络赚取了最高的利润,但由于明年制作成本不可避免地增加,其利润预计将降至Vidnet节目平均水平以下。因此,如果Vidnet用一个具有平均受欢迎程度和制作成本的节目取代《星光》,它的总体利润将会更高。 - **核心论点**:因为《星光》明年制作成本增加导致利润将低于平均水平,所以用平均受欢迎程度和制作成本的节目替换它能让总体利润更高。这里的论据就是《星光》因成本上升利润会下降,论点是用普通节目替换它能提升总体利润。 - **正确答案方向**:需要找到能说明即使《星光》利润下降但也不能用普通节目替换它(即替换后未必能提升总体利润)的理由,可能涉及到《星光》对于其他节目的带动作用、替换后的潜在负面影响等方面。 - **A选项**:Vidnet节目在过去三年平均利润每年都在增加。这与用普通节目替换《星光》能否提高总体利润无关,不能削弱论点,排除。 - **B选项**:在非常受欢迎的节目之前和之后的时段播出的节目往往会比其他情况下有更多的观众。这说明《星光》虽然自身利润会下降,但它能带动其前后节目的观众数量,从而可能对总体利润有积极影响,不能轻易用普通节目替换它,有力地削弱了论点,当选。 - **C选项**:《星光》目前是Vidnet所有节目中制作成本最高的。这只能说明《星光》成本高的现状,不能反驳用普通节目替换它能提高总体利润这一观点,排除。 - **D选项**:去年Vidnet在一个与《星光》非常相似且在不同日子播出的周播节目上亏损了。这与《星光》以及用普通节目替换它能否提高总体利润没有直接关联,排除。 - **E选项**:即使由于制作成本增加,《星光》的利润低于Vidnet节目的平均水平,它仍将比所有网络的电视节目平均利润高。但这并不能说明不应该用普通节目替换它来提高Vidnet自身的总体利润,排除。 综上所述,正确答案是B。
