OG23的解释－－有点糊涂

23. A Labor Department study states that the numbers of women employed outside the home grew by more than a thirty-five percent increase in the past decade and accounted for more than sixty-two percent of the total growth in the civilian work force.

(A)              numbers of women employed outside the home grew by more than a thirty-five percent increase

(B)              numbers of women employed outside the home grew more than thirty-five percent

(C)             numbers of women employed outside the home were raised by more than thirty-five percent

(D)             number of women employed outside the home increased by more than thirty-five percent

(E)              number of women employed outside the home was raised by more than a thirty-five percent increase

Because a count of women employed outside the home at any given time will be expressed by a single number, the use of the plural noun numbers in choices A, B, and C is illogical. In A, the phrase grew by more than a thirty-five percent increase is redundant and wordy, since the sense of increase is implicit in the verb grew. In C and E, the passive verb forms were raised and was raised are inappropriate because there is no identifi­able agent responsible for the raising of the number of women employed. In choice E, was raised by ... increase is redun­dant. Choice D, which presents the comparison logically and idiomatically, is the best answer.

看过以前的讨论稿，也知道a number of, the numbers of的用法，但是对于Because a count of women employed outside the home at any given time will be expressed by a single number这句话的理解还是想make sure 一下：

是不是因为这个句子需要表达的是在外工作的妇女的数量所以才用the number of呀？

since the sense of increase is implicit in the verb grew这句话又应该怎么理解呢？说实话，对increase, raise, grew的用法我真的不是很清楚。如果有nn帮着解释一下就谢谢了。

任何时候出门工作的妇女都只可能是一个确定的数字，不可能有两个数字，用单数。

since the sense of increase is implicit in the verb grew：因为GREW已经暗含乐INCREASE的意思，重复~~

INCREASE, RAISE ,GROW的用法请查字典，RAISE只能用做VT，后要接宾语，而其它两个可以用作VI也可以用作VT~~
