A major chemical spill occurred five years ago at Baker’s Beach, the world’s sole nesting ground for Merrick sea turtles, and prevented nearly all the eggs laid that year from hatching.Yet the number of adult female Merricks
returning to lay their eggs at Baker’s Beach has actually increased somewhat since five years ago.Clearly, environmentalists’ prediction that the world’s Merrick
population would decline as a result of the spill has proven unfounded.

Which of the following, if true, most seriously undermines the argument offered in refutation of the environmentalists’ prediction?

A.The chemical spill five years ago occurred at a time when there were neither Merrick sea turtles nor Merrick sea turtle eggs on Baker’s Beach.

B.Female Merrick sea turtles begin returning to Baker’s Beach to lay their eggs when they are ten years old.

C.Under normal conditions, only a small proportion of hatchling female Merrick sea turtles survive in the ocean until adulthood and return to lay their eggs at Baker’s Beach.

D.Environmental pressures unrelated to the chemical spill have caused a significant decline in the population of one of the several species of sea birds that prey on Merrick sea turtle eggs.

E.After the chemical spill, an environmental group rejected a proposal to increase the Merrick sea turtle population by transferring eggs from Baker’s Beach to nearby beaches that had not been affected by the spill.

这题我在B\D间犹豫了一下，最后选了D，请高人指点一下为什么选B啊？

回来产卵的龟都是十年前的，跟五年前的事故无关……

题目的最后一句为什么推测是decline，不应该是增加了吗？
楼上的能不能再解释下，还是没想明白~~~

姐帮你直白的翻译一下。 很明显，环保主义者提出的关于M数量减少的推测（作为。。的结果）是错的。

我觉得选b, 题目中说了因为回来产卵的龟多了，所以数量不会减。b选项说的意思是之所以回来的龟多了，那是因为现在这些回来的龟还没有受到影响，他们是十年前走的。换句话说就是，影响肯定会有的，就是没到时候呢。 就是驳斥了论据。选b
