FeiFei135中的31,32

Political opinions and analyis outside the mainstream rarely are found on television talk shows, and it might be thought that this state of affeirs is a product of the political agendaof the television atstions themselves. In fact, television ststions are driven by the same economic forces as sellers of more tangible goods. Because they must attempt to ca[ture the largest possible share of the television ordience for their shows, they air only those shows that will appear to large number of people. As a result, political opinions and analysis aired on relevision talk ahows are typically bland and innocuous.

31 An assumption made in the explanation offered by the author of the passage is that

A most television views cannot agree on which elements of a particular opinion or analysis are most distrubing.

这两题是大假设里套小假设，31题是EXPLANATION 中包含的假设 ，32题是EXPLANATION依据的假设，但理不清题干中的逻辑层次关系,两个假设就把我弄晕了,希望XDJM帮忙一下.谢谢~~~~~~~~~

文章的推理链是这样的
电视台寻求经济利益最大化---抓住最大的观众份额---播出的政治观点是中庸的******最终结论

两道问题全使假设，不是大假设套小假设，而是你看到上面第一步和第三步推理的架桥

第一个桥：为什么追求利润最大化就要抓住最大的观众份额？因为总有观众的意见不统一然后就不看这个节目，我们才需要顺从主流民意，抓大放小，如果大家不会因为意见不统一而拒绝看节目，那就没有必要抓大放小了，随便播什么都行。

第二个桥：为什么播出的政治观点是中庸的就能得出最终结论？再架桥，中庸的观点一般是主流的。

两个假设各针对一个文中给的解释。

31. Because they must attempt to capture the largest possible share-->olitical opinions and analyis outside the mainstream吸引的人要少过mainstream，所以不播。

32.political opinions and analysis aired on relevision talk ahows are typically bland and innocuous-->olitical opinions and analyis outside the mainstream不播，播的应该是inside the mainstream的。
