原谅我用一个“奇异的”title把各位吸引进来。。。

Tiger sharks are common in the waters surrounding Tenare Island. Usually tiger sharks feed on smaller sharks, but sometimes they have attacked tourists swimming and surfing at Tenare's beaches. This has hurt Tenare's tourism industry, which is second only to its fishing industry in annual revenues. In order to help the economy, therefore, the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of the beaches.
Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence?
(A) Even if not all the tiger sharks that come close to the beaches are killed, the existence of the program would reassure tourists.
(B) Business owners who depend on tourism are willing to pay most of the cost of implementing the program.
(C) Tourists come to Tenare Island for its beaches, even though the island features a number of other tourist attractions.
(D) The small sharks on which tiger sharks prey feed on fish that are commercially important to the island's fisheries.
(E) Not all tourists who come to Tenare Island enjoy swimming or surfing.这道题刚做的时候觉得没有正确答案。但是觉得BCDE都有点儿离谱，所以选了A。现在的问题是题目的意思表达。
虎鲨吃小鲨鱼，杀掉虎鲨，小鲨鱼对捕鱼业重要，这不是意味着对捕鱼业不是有利吗？除非按照题目理解，这些虎鲨是通过人工feed的，杀掉虎鲨后这些对这些养小鲨鱼的渔民就很不利了。但是虎鲨又怎可能被人工feed呢？feed也没有以…为食的意思（据longman）。所以题目有点儿奇怪。
望各位NN解答下～
不知道现在我的新理解对不对？
D的意思是，虎鲨吃小鲨鱼，小鲨鱼吃鱼，而鱼对捕鱼业很重要。所以虎鲨减少，鱼减少，捕鱼业就不利了。
题目的意思是：在T岛周围的虎鲨以小鲨鱼为食，但是有时也会攻击海边游泳的游人，政府为了保护旅游业而射杀虎鲨（旅游也是第二产业，第一产业是渔业）
要想WEAKEN的话，就是射杀虎鲨是错误的。D选项正好WEAKEN了，D的意思是：虎鲨捕食的小鲨鱼是以渔民养殖的鱼为食的。（要是把虎鲨都射杀了，那么小鲨鱼就多了，渔民的鱼就遭殃了啊）
The small sharks on which tiger sharks prey
feed on fish that are commercially important to the island's fisheries.
红的是定语从句，蓝的是主句谓语，你看清了吧？？
我当时看D也觉得反了。。但是觉得按照ETS的出题方法，它既然原文有提到渔民，经济什么的，那就这个吧
看了解释才明白是这样子的。。。。
理解的很深刻
唉，看来还是阅读能力有限啊，我也看成小鲨鱼对渔业是重要的了。
BS自己一个。
