Question

Which sentence from the passage should be removed or replaced in order to maintain the existing style of the article?
A.
Often these events have large impacts, but fortunately, they occur less often.
B.
Discharge from faulty or damaged factories or water treatment systems is also considered point source pollution.
C.
One of the biggest sources of pollution is called nonpoint source pollution, which occurs as a result of runoff.
D.
Bucketloads of pollutants that creep into the ocean come from activities on land.

Answer 1

D

Reason: It's informal and figurative ("Bucketloads... creep into the ocean") and clashes with the article's more formal, explanatory tone. Replace with a neutral sentence such as: "Large amounts of pollutants that enter the ocean originate from human activities on land."
