The computer company has announced that it will purchase the color-printing division of a rival company for $950 million, which is part of a deal that will make it the largest manufacturer in the office color-printing market.
A) million, which is part of a deal that will make
B) million, a part of a deal that makes
C) million, part of a deal making
D) million as a part of a deal to make
E) million as part of a deal that will make
这题答案是E。解释上说deal不等于million，不能使用同位语，并且也不能是概括性同位语。

这题答案是D
解释说increase是概括性同位语。
后来又查了manhattan的帖子，Ron 的解释是：
if you have an appositive modifier that's an abstract noun - such as "strategy", "figure", "statistic", "findings", "situation", "change", "difference", etc. - then such an appositive may be allowed to describe the entire situation described in the previous clause.
for instance, the example i gave above with "a strategy..."
also, for further examples, see #59 and #79 in the purple verbal supplement OG book.
in #79 this modifier is part of the underline and is useful in choosing the correct answer. in #59 it's not part of the underline, so you don't have to use it, but you're exposed to it so that you can use it later.
但是我在这两道题中都没有看到类似的词语，为什么一个可以使用概括性同位语，另一个不可以呢？
非常非常不清楚，恳请NN解释一下！！
