Hi @hannah93092, thanks for your post.

This stimulus presents a set of facts that are specific to a particular place ("a large river nearby" has polluted "a vast ocean region" in which "few fish can survive"). Answer choice (E) can be eliminated because it is too general - "in a body of water in general" is not textually supported. All we know anything about is what is happening in this specific ocean region in particular.

Hope this helps! Please let us know if you have any additional questions.
