※ 引述《kenting15 (我不像我)》之銘言： : 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~! 因為烏龜十年後才會回到棲息地下蛋因此五年前的化學污染而導致龜蛋無法孵化的後果尚未顯現換而言之可能是因為過去10~15前龜蛋孵化良好所以這五年來才會有那麼多烏龜回來下蛋並無法證明五年前的意外對海龜沒有造成影響因此和年齡有直接關係若B為真那則削弱結論(->污染並不影響孵化) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 124.8.12.96 ※ 編輯: Calla 來自: 124.8.12.96 (07/14 19:20)
