GWD题
A major chemical spill occured 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 5 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' prediciton?

答案是：Female Merrick sea turtles begin returning to Baker's Beach to lay their eggs when they are ten years old.

我想问下这个答案怎么就undermine the argument了？我想了很久都没想明白~

楼主要看其他4个选项是不是有问题从而可以排除，逻辑还是用排除法更快些，找错的比找对的更容易，只要明白哪些是错的，剩下的那个为什么对就不用折磨自己使劲琢磨了。。当然楼主要完美主义，得花多一些时间了。。
