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. Which one of the following, if true, provides the most support for the argument's conclusion? ['Waterbirds are typically much more abundant in areas that serve as nurseries for juvenile waterbirds than in areas that do not.', 'Waterbirds use still waters as nurseries for juveniles whenever possible.', "The waters around the islands neighboring Shooter's Island are much rougher than the waters around Shooter's Island.", "The number of juvenile waterbirds around Shooter's Island, as well as the number around each neighboring island, does not fluctuate dramatically throughout the year."]
