[問題] PP1-CR 4
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 題目最後是問說 解釋為何在海灘的海豚的後代life expectancy低於野外!
E是說 因為在海灘的海豚花比較少的時間教他的後代捕魚
這樣可以解釋life expectancy低於野外嗎?? 選的很沒把握
(A) 我不知道a哪裡錯耶 但我還是覺得很怪! 是因為他比較的是beach 所以無關嗎
(B) 反駁! 有母的海豚可以照顧 刪
(c)跟魚的種類沒啥關係 刪
(D) 我看到only這絕對字眼就先不考慮了
思路很亂 請指教 我這樣想對嗎
感謝

日情蒐點名--郭勇志︰會怕就好
〔記者羅惠齡／台中報導〕今年日本出版的新球季日本職棒球員名鑑，在分析亞錦賽議
題中，將郭勇志列為台灣隊注目投手之一，郭勇志不好意思地表示，大概是去年成績不錯
，被注意到了。將郭勇志列入要特別注意的球員，是因為他去年獲得聯盟救援王，控球
、直球速度及壓制能力都不錯，有機會獲國家隊青睞。看到自己被日本人注意到，郭勇
志意外之餘也表示︰「會怕就好。」
