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 be properly drawn from the statements 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）

(E) The outcome of a presidential election is substantially affected by factors other than the ideological positions of the candidates.

答案是E。

不过实在搞不明白这句话的逻辑关系，请牛牛指教，多谢了！

版主，看了前人得讨论，只有一个帖子，讲的也很含糊，没有看明白才发问的，请帮忙。另外，版主能不能更改一下回答问题的方式，我想大家在这里都有几个月了，都是了解这里的规矩的。

Hi,dongchuang,

這題我也迷惑了好一段時間,大概想出個所以然來了,試著回答一下,若有錯誤可別見笑呀!

題目說real disposable income 增加,則選票增加,又舉了一個例子是real disposable income 減少,則輸了選舉的例子,所以能很確定的說" 改善老百性的經濟情況是能否當選的重要條件".

因此可推出ANS(E),候選人的意識型態不是重要的條件.

我覺得答案(E)也可算是對原文的Support.
