PrepTest 84, Section 3, Question 6
The waters surrounding Shooter's Island have long been a dumping ground for ruined ships and boats, and the wreckage there has caused these waters to be exceptionally still. An ornithologist found that the overall abundance of waterbirds around Shooter's Island is similar to that around each of the neighboring islands, but that juvenile waterbirds are much more abundant around Shooter's Island than around those other islands. This suggests that the still waters around Shooter's Island serve as a nursery for the juveniles.
