问几道题 求大家帮忙解答 不胜感激 请大家帮忙解答这样几道语法题
1. The number of undergraduate degrees in engineering awarded by colleges and universities in the United States increased by more than twice from 1987 to 1985.
A. increased by more than twice
（by 后加百分比）
B. increased more than two times
(Awkward）
C. more than doubled
（过去发生的客观事实，double做动词）
D. was more than doubled
(改变句意，number不能被加倍)
E. had more than doubled
（时态错误，不是延续动作）
正确答案是C，这是为什么呢，我只知道B是肯定不对的
2. The British Admiralty and the War Office met in March 1892 to consider a possible Russian attempt to seize Constantinople and how they would have to act militarily to deal with them.
A. how they would have to act militarily to deal with them
（代词模糊）
B. how to deal with them if military action would be necessary
（if改变句意）
C. what would be necessary militarily for dealing with such an event
(介词使用错误)
D. what military action would be necessary in order to deal with such an event
(what引导的名词性从句，所以可以和同为名词的attempt并列)
E. the necessity of what kind of military action in order to take for dealing with it
（改necessary词性从而该句意）
正确答案是D,可是，名词attempt怎么能和what引导的从句并列呢
