Since the new publisher took control, a news magazine’s covers have featured only models and movie stars. Previously, the covers had displayed only politicians, soldiers, and business leaders. A leading gossip columnist claimed that the changes made the magazine relevant again. However, many newspaper editorials disagreed and suggested that the new publisher is more interested in boosting sales than in reporting important news events.
Which of the following is an assumption necessary for the argument made by the gossip columnist’s opponents?
A.The charitable activities of models and movie stars often focus public attention on pressing problems.
B.Final authority for choosing the cover subject of the magazine lies with the publisher.
C.A magazine can boost sales while highlighting the coverage of important world leaders.
D.Some of the movie stars featured are now running for political office.
E.Magazine issues with models or movie stars on the covers are purchased at a rate more than three times greater than is the case with issues featuring politicians on the covers.

答案是B，一直没想明白，希望大神解答~~

个人感觉，这题既不是样本问题，又不是方案问题，类比问题，只能按相关到因果解释
逻辑链： new publisher ---> covers from politician to movie star-->reason(out of the boost of sales not the important news event)
那实际上有两个gap，我第一眼看B 感觉是是第一个gap，但是我个人感觉第一个gap不是主要gap，因为乍一看肯定是觉得gap应该是movie star 的封面有更多人买，但是E选项没有解释the important news event 的问题，就是说E还要补充movie star 通常来讲都不是important news event 。所以经过排除选B，而且最后看B 也是可以适用于整个gap的。

同意楼上的，相关因果问题。 publisher更换，和版面更换，2件事其实没有什么因果性。如果非要建立联系，要说明。问题的是专栏家的反对者的假设，其实也是说这些改变和publisher的更换到底相不相关。

我理解的是果因问题，
如果结果是new publisher 换了封面，gossip columnist 觉得原因肯定是new publisher想让杂志变得更relevant。 cq 是找它因解释果，或者证明果和因之间没有联系。b等于是说如果final authority for choosing the cover subject of magazine 都不在publisher 手上，等于说因果没有关系。请问这样理解对吗？而且我觉得如果是相关因果的话e不等于是符合独立第三因素，其他原因导致了换封面吗？
