1. Each increase of 1 percent in real disposable personal income per capita will increase the share of the electorate for an incumbent by about 2.2 percentage points, other things being equal. Since 1952 there has been a decline in real disposable income during only one presidential election year. The incumbent lost that election.
Which of the following conclusions can properly drawn from the statement above?
A. When an incumbent runs for office, he or she is likely to win.
B. Political parties should take care to put forth a candidate who seems prosperous.
C. Presidential candidates should put their greatest efforts into improving their public image.
D. Because a presidential campaign requires the expenditure of large amounts of money, it frequently impoverishes a candidate and his or her supporters.
E. The outcome of a presidential election is substantially affected by factors other than the ideological positions of the candidates.



求详解，我其实觉得没有一个选项可以让我建立联系。谢谢诸位

答案是E么？

题干说大致说的就是选举的支持率是和人们的可支配收入成正比的，1952年人们可支配收入下降，所以那一年现任政府输掉了选举。

E就是说，除了参选人的政治立场（其实我也不完全清楚什么是ideological positions）还有其他因素会影响选举的结果。正好这里的其他因素就和题干里的可支配收入成为了对照。

这样也可以，他也没说其他因素就是可支配收入啊

谢谢你

是没说拉。。不过可以推出来嘛。而且貌似其他选项也没有比E更合理了。。
