Answers -

32). D is the best choice - the phrase sediments from the Baltic Sea tells where the sediments originate, findings provides a noun for consistent to modify, and in the area clearly identifies where the industrial activity is growing.

A, B - incorrect - ambiguity - the words "which" and "where" appear to refer to sediments

E - incorrect - it is not clear what consistent describes.

A, C, E - incorrect - there is no logical place to which "there" or "its" could refer.

33). Choice C is best - the participle "protecting" begins a phrase that explains what the shields did.

A , B - incorrect - awkwardly use the singular word "method" to refer to items of military equipment rather than to the use of such items. Also, a method of protecting would be more idiomatic than a method to protect in A or a method protecting in B.

B , D - "as" is incorrect; also, a protection in D has no noun for which it can logically substitute.

E - is incomplete; used to protect would have been acceptable
