动作的比较和名词的比较?

动作比较用as.名词比较用like. 由逻辑意思怎么判断是什么的比较?   感觉不好操作.比如下面这个:

12-27. As virtually all the nation’s 50 busiest airports are, New York’s were built for an age of propellers, before jet planes weighing 800,000 pounds needed over two miles of runway.

(A) As virtually all the nation’s 50 busiest airports are

(B) As with virtually all of the nation’s 50 busiest airports

(C) Like virtually all of the nation’s 50 busiest airports

(D) Like the cities where virtually all the nation’s 50 busiest airports are（C）

(E) Like other cities where virtually all the nation’s 50 busiest airports are

A有歧义. 如果A改成As virtually allof the nation's 50 busiest airports are是不是也可以呢? 而C是两个名词比较.

是不是都可以? 最好不要用这个判断点判断?
