Mayor: Migrating shorebirds stop at our beach just to feed on horseshoe-crab eggs, a phenomenon that attracts tourists. To bring more tourists, the town council plans to undertake a beach reclamation project to double the area available to crabs for nesting.
Birdwatcher: Without a high density of crabs on a beach, migrating shorebirds will go hungry because shorebirds only eat eggs that a crab happens to uncover when it is digging its own nest.
Which of the following, if true, would provide the mayor with the strongest counter to the birdwatcher’s objection?
（A）Every year a certain percentage of crabs are caught by fishermen as bait for eel traps.
（B）Horseshoe crabs are so prolific that given favorable circumstances their numbers increase rapidly.
（C）On average, tourists who come to the town in order to watch birds spend more money there than tourists who come for other purposes.
（D）The additional land made available by the reclamation project will give migrating shorebirds more space.
（E）Some of the migrating shorebirds make only one stop during their migration form South America to Canada.
题目分析：A说每年crab被渔夫当作鱼饵，扯，杀。B说crab的数量会急剧上升。原文说地方大了密度就会变小，这个选项的出现降低了密度变小的可能性，留着。C说游客看鸟花的钱比为了其他目的花的钱多，没说，杀。D说还有另外的土地，范围与原文就没关系了，杀。E说一些鸟只停一次，没说过，杀。
