[face=Georgia]Political opinion and analysis outside the mainstream rarely are found on television talk shows, and it might be thought that this state of affairs is a product of the political agenda of the television stations themselves. In fact, television stations are driven by the same economic forces as sellers of more tangible goods. Because they must attempt to capture the largest possible share of the television audience for their shows, they air only those shows that will appeal to large numbers of people. As a result, political opinions and analyses aired on television talk shows are typically bland and innocuous.
31. An assumption made in the explanation offered by the author of the passage is that (A) most television viewers cannot agree on which elements of a particular opinion or analysis are most disturbing. (B) there are television viewers who might refuse to watch television talk shows that they knew would be controversial and disturbing. (C) each television viewer holds some opinion that is outside the political mainstream, but those opinions are not the same for everyone. (D) there are television shows on which economic forces have an even greater impact than they do on television talk shows. (E) the television talk shows of different stations resemble one another in most respects.
If ,contrary to B,television watchers accept all kinds of talk shows,including controversial and disturbing ones, the tele stations need not to air only those that are typically bland and innocuous in order to attract the majority of audience, thereby weakening the conclusion. So the choice B is best.
by the way,1stzhang, i suggest you that when dealing the assumption questions you'd better focus on the evidence without which the tenability of the conclusion will be undermined,that is, seek the essential condition required by the conclusion.At least it seems to me, it is a quicker way to find the answer.
