我觉得E更好点,about 表示大约的意思啊, 郎文字典里的解释如下:

about adv.
a little more or less than a particular number, amount, or size
synonym roughly

I live about 10 miles away.a tiny computer about as big as a postcard

这里的about Colorado's size 是说明59million的啊.

请指教!

我是这样理解的：

OG里不是说:The absence of an area in B and E impairs clarity: the phrase beginning with about must modify a noun such as area that is logically equivalent to the number of acres given.

也就是说about前必须要有名词，而E中about前是逗号。

定语从句的that: 省略

宾语从句的that: 不省

I think:

1. I am talking about the book (that is ) sold by XDF.

定语从句, that +be : "that" can be omitted though "that" is not 宾语 in 从句.

After "taht" is omiited, it changes to "FengCI or BeiDong Tai"  for noun.

2. I am talking about the book (that) she mentioned yesterday.

宾语从句,"that" can be omitted

3. I am talking about the book that fell on the table.

定语从句,"that" can NOT be omiited, if omitted, 从句 will has no o.

定语丛句：

1 that做定从中主语，不可省。

there is a girl that(who) has green hair.

2 that做定从中宾语，可省，也可不省。

there is a book (that) you have not read.

3 有that be/which be引导的定从，能省就省。

there is a book (that was) borrowed by  mary yesterday.

about the size of Colorado 是介词短语做定语,比重句更简洁, which is my idea. Suddenly, I cannot type in Chinese. Sorry for that.

area 是 acres的同位语，跳跃修饰这个单词。

hughes0305

(C) has grown from 48 million to nearly 59 million, an area about the size of Colorado
    

nearly 59 million, (which is) an area about the size of Colorado. Therefore, an area refers to "nearly 59 million acres".

nearly 59 million, (which is) an area about the size of Colorado. Therefore, an area refers to "nearly 59 million acres".

Since 1981, when the farm depression began, the number of acres overseen by professional farm-management companies has grown from 48 million to nearly 59 million, an area is about the size of Colorado .

The absence of an area in B and E impairs clarity: the phrase beginning with about must modify a noun such as area that is logically equivalent to the number of acres given.

an area是作为the number of acres的同位语，在这里area的意思是面积，例：an area of 100 sq. meters 面积100平方米 (金山词霸).这样OG的解释也就迎刃而解了。

an area...并不是同谓语，而是独立主格结构：

到底是同谓语还是独立主格结构阿？

为什么是独立主格呢？

crowkiller

我同意是同位语。

独立主格和前面不存在对应关系，这个同位语有前面对应的。NN已经说的很清楚了。
