标题: 利用有关无关的方法一下子上来就把正确选项杀了，求助啊

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?

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

答案选的B，怎么都没想到是B，我觉得第一次做一上来肯定就杀掉B了，哪里还想那么多啊，这要是在考试又要挂了，这种题算650+的水准吗
