A popular beach has long had a dolphin feeding program in which fish are given to dolphins several times a day; many dolphins get as much as half of their food each day there. Although dolphins that first benefit from the program as adults are healthy and long-lived, their offspring have a lower life expectancy than offspring of dolphins that feed exclusively in the wild. Which of the following, if true, most helps to explain the lower life expectancy of offspring of dolphins feeding at the beach compared to other young dolphins? (A) Sharks that prey on dolphins are less common in the open seas off the beach than in many other areas of the open seas where dolphins congregate. (B) Many of the adult dolphins that feed at the beach are females that nurse their offspring there. (C) The fish given to the dolphins at the beach are the same types of fish that dolphins typically catch in the wild. (D) Many dolphins that feed at the beach with their offspring come to the beach only a few times a month. (E) Adult dolphins that feed at the beach spend much less time teaching their offspring how to catch fish in the wild than do other adult dolphins. 答案E 题目最後是问说 解释为何在海滩的海豚的後代life expectancy低於野外! E是说 因为在海滩的海豚花比较少的时间教他的後代捕鱼 这样可以解释life expectancy低於野外吗?? 选的很没把握 (A) 我不知道a哪里错耶 但我还是觉得很怪! 是因为他比较的是beach 所以无关吗 (B) 反驳! 有母的海豚可以照顾 删 (c)跟鱼的种类没啥关系 删 (D) 我看到only这绝对字眼就先不考虑了 思路很乱 请指教 我这样想对吗 感谢 -- 日情蒐点名--郭勇志︰会怕就好 〔记者罗惠龄／台中报导〕今年日本出版的新球季日本职棒球员名监，在分析亚锦赛议 题中，将郭勇志列为台湾队注目投手之一，郭勇志不好意思地表示，大概是去年成绩不错 ，被注意到了。将郭勇志列入要特别注意的球员，是因为他去年获得联盟救援王，控球 、直球速度及压制能力都不错，有机会获国家队青睐。看到自己被日本人注意到，郭勇 志意外之余也表示︰「会怕就好。」 --
