32. GWD30-Q32: B 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? B. Female Merrick sea turtles begin returning to Baker’s Beach to lay their eggs when they are ten years old. 我自己定義的因果關係為 因:母龜跑回來下蛋的隻數增加 果:化學污染問題的影響沒有出現 其他的答案我都排除掉了 但不知道為什麼因果關係跟烏龜的年齡有關...... 請問大家 感謝~! --
