og的解释Grammatical construction; ParallelismThe main point of this sentence is to identify the federal government as the largest single provider of children’s day care. It goes on to illustrate this with two examples that need to be presented in grammatically parallel form. Because the second example is given as a relative clause beginning with which supported private, the first example must be similarly presented. The opening statement must therefore present government as the predicate noun so that which clearly refers to government in both of the examples.
A Tie two examples are not in parallel form; the first begins with a present participial, offering, while the second is presented as a relative clause, which supported. . . .

楼主我的观点是这样的。
这个句子，我们首先要弄清楚有那个parallelism的成分。从小到大，第一个是child care 和educational services，第二个是X（X肯定是个从句）and which supported private day care facilities...,那我们就需要知道，究竟which指向了何处。从意思可以知道，which指的是the federal government。根据gmac的喜好，which仅仅能指向主句中离他最近的Noun，所以the federal government必须要最接近which，所以我觉得应该选E。
至于A和D为啥不行，A中，offeringXXX是分词形式，木有办法和后面的which从句parallel。
而D中的offering也是分词形式，如果是noun modifier 他修饰the federal government时，不需要逗号；如果是verb modifier 那么他和主语provider无关。

啊，谢谢，懂了！没看到后面是which supported。。。不过有一个疑问，这道题是当初我上课的时候的，旁边写了一句表示一次性而不是重复做，这样讲得通吗？
