题目选项分析

A popular beach has long had a dolphin feeding program in which fish are given to dolphins several times a day; many dolphins get as much as half of their food each day there. Although dolphins that first benefit from the program as adults are healthy and long-lived, their offspring have a lower life expectancy than offspring of dolphins that feed exclusively in the wild.

Which of the following, if true, most helps to explain the lower life expectancy of offspring of dolphins feeding at the beach compared to other young dolphins?

【选项】Sharks that prey on dolphins are less common in the open seas off the beach than in many other areas of the open seas where dolphins congregate.

选项是否正确?

捕獵海豚的鯊魚在沙灘附近的海域比在其他海豚聚集的地方更不常見:無關吧
就是說鯊魚更喜歡在海豚聚集的地方?那聚集起來吃飼料的海豚更容易被吃啦
