3.     The United States has never been a great international trader. It found most of its raw materials and customers for finished products within its own borders. The terrible consequences of this situation have become apparent, as this country now owes the largest foreign debt in the world and is a playground for wealthy foreign investors. The moral is clear: a country can no more live without foreign trade than a dog can live by eating its own tail.

In order to advance her point of view, the author does each of the following EXCEPT:

(A) draw on an analogy

(B) appeal to historical fact

(C) identify a cause and an effect

(D) suggest a cause of the current economic situation

(E) question the ethical basis of an economic situation

答案：E。请问这道题为什么是E呢？原文里面明确写出了“The moral is clear：。。。”还是因为说原文虽然有这样写但是冒号后面的内容根本没有涉及到moral方面的内容，这是原文本身存在的一个逻辑漏洞呢？请大牛牛指教！
