[求助]一道改错

改错

The number of undergraduate degrees in engineering awarded by colleges and universities in
the United States increased by more than twice from 1978 to 1985.
(A) increased by more than twice
(B) increased more than two times
(C) more than doubled
(D) was more than doubled
(E) had more than doubled
 

我不知道答案是什么，也不知道则么分析这道题目。。。1978 to 1985. 是不是要用完成时？double用主动被动？赐教。。。

E 吧  给出时间段了 用完成时比较准确 

double 用主动 比如 The house has doubled in value since I bought it. 就是加倍的意思

下面是哥prep的例子 看看double的用法

In the Louisiana Purchase of 1803, the United States acquired 828,000 square miles for about four cents an acre, which more than doubled the country's size and that brought its western border within reach of the Pacific Ocean.

(A) In the Louisiana Purchase of 1803, the United States acquired 828,000 square miles for about four cents an acre, which more than doubled the country's size and that brought

(B) For about four cents an acre the United States acquired, in the Louisiana Purchase of 1803, 828,000 square miles, more than doubling the country's size and it brought

(C) With the Louisiana Purchase in 1803, the United States acquired 828,000 square miles for about four cents an acre, more than doubling its size and bringing

(D) The United States, in the Louisiana Purchase of 1803, for about four cents an acre, acquired 828,000 square miles, more than doubling the country's size, bringing

(E) Acquiring 828,000 square miles in the Louisiana Purchase of 1803, the United States bought it for about four cents an acre, more than doubling the country's size and bringing

那这里谓语动词是DOUBBLE吗，则么感觉more than doubled有些奇怪啊。。。

还有我用increase为什么不可以呢。。。有谁能给我详细的讲讲这个题吗。。。。。谢谢拉
