请问OG38题

38. Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.
(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

My question is whether the phrasing, "findings" in D, is the same function as 'concentrations' in the sentence?

还有一个问题是：是不是所有的以形容词开头的分句，都可以认为是awkward的，比如题目中的：consistent with the growth of industrial activity there。

我感觉findings在本题中是指代前面整句的意思，起非限定性定语从句的作用，因此不能简单将findings与concertrations对等。

如果按照我们以前学过的语法，which也是可以引导非限定性定语从句的，但在GMAT考试中这种用法是错。

有个问题还是非常地confused:  

findings consistent with...到底是同位语,还是独立主格结构???

我个人偏向于认为是同位语,相当于findings (that are) consistent with...

OG Verbal Review上说findings refers back to
            the scientists' observations. 貌似也是在暗示这是同位语从句.现在的关键就是搞清楚同位语是否能指代一句话,之前看到的例子都是有明显指代物的. 

例:OG11-72,110,114    VerbalReview-16,77
