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.
正确答案为：
sediments from Baltic Sea, findings consistent with the growth of industrial activity in the area.
后面的解释有一个地方我不理解，它说：
Findings refers back to the scientists' observations.
如果findings是一个同位语的话主句里应该有相对应的主语名词啊，为什么答案说它直接指代了前面的动作？如果要指代前面这句话的话为何要用复数？
是不是指代了concentrations？
如果是独立主格的话，我觉得findings这一句跟前面基本没有任何类似因果条件时间之类可以使用独立主格的关系啊。。。。。
另外为什么不能改成：
Baltic Sea sediments, where the growth of industrial activity is consistent with these findings.
(答案说里面的where指代不明确，但是我觉得可以直接指代Baltic Sea sediments嘛。。。。)
感激不尽！
