举个例子he is twice as strong as he was。注意比较对象A中是twice as fast as the 1970’s 在这里是rate ...

1970's是指20世纪70年代吗？

B 和C的区别在于句子含义，不能够说in 1999 rate of increase of A is nearly twice as fast as it was in  ...

同意!这个才是正答！关键是在于rate是一个数字，数字是可以比较大小，用倍数来形容的，但是一个数字不能用fast，再加上two times的表述错误，排除法就OK啦

时隔这么久翻到这个帖子，估计层主已经不需要解答了。但是还是说一下我的看法吧。这题我也想了很久，但是后来突然反应过来好像是倒装！
还原后就是but assembly lines came off twice that number of trucks alone in 1929.
还原过后感觉明朗了很多！这里的twice还是和上面一样的adv的用法，twice + n 这里的n指 that number， that指上文的总数469000，如果用the，则会有歧义的感觉。
这题想要表达的意思是 1914年，美国生产了469000量小汽车和卡车，但是到了1929年，卡车的产量就已经是1914年两车之和数量的两倍了。 所以这里必须用that，指代469000.

小小明噢耶

Forum:--twice/two times/double
Twice = Adverb - modifies verb, adjective or another adverb
Double = Adjective - Modifies noun
Twice can be used to answer "How/how many" one did something.
Double is used to show "what" one did.
I ran to the store twice.
I bought double books than usual.

我个人认为，double具有动作的含义，所以如果前面有发出动作的词，就使用Twice应该会好（如有不对请指出！！）
goggle了一下---difference between twice and two times
1、        two times—在非正式场合用，比如和朋友说话
2、        twice—书面语
（但我觉得奇怪，难道gmat里所有题的正确答案里没有two times的吗？）
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
© more than doubled
(D) was more than doubled
(E) had more than doubled
C correct：
A - increased more than twice - well how about simply saying "more than doubled". Conveys the same info much more succinctly
(B) increased more than two times : When the number of degrees "increased more than two times," that means over the period of 1978 to 1985, it has gone up at least twice: maybe in 1980 and then in 1981. The other times, it has stayed steady or gone down.
