328. 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 un founded.

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 occured 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 hatching 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.

XDF书上给的答案是B，我选的是C， 哪位NN来解释一下啊？

C也应该是削弱的一种阿？海龟回来这么多明显反常阿？

我觉得应该是B阿，C说只有一小部分雌海龟会在b产软和题干说的5年后在B产软

的海龟“稍微”多了一些完全没有相关联的关系；如果楼主觉得c暗示了反常，那么

这种反常也不能和B的削弱程度相比：产卵的海龟都要长到10岁，而现在比5年前反

而多了，说明5年前的泄漏并没有使海龟数量减少--直接和题目结论相关；
