On Pacific islands, a newly arrived gecko species, the house gecko, is
displacing the previously established mourning gecko in urban areas, but
populations of the two species are more stable in rural areas far from human
settlement. The house gecko does not attack the mourning gecko, but in areas
where insects congregate it prevents the mourning gecko from feeding on them.
Which of the following contributes most to an explanation of the difference
between gecko populations in urban and rural areas?
(A) In urban areas, geckos are valued because they eat so many insects.
(B) Geckos defend territories against other members of the same species.
(C) House geckos that arrive on islands are carried there in boats and
planes.
(D) In places where there are lighted buildings, insects tend to gather
around the light.
(E) Mourning geckos are all females and reproduce asexually, but house gecko
reproduce sexually.
答案D
最後問gecko在城市和鄉下的差異
請問跟燈光有什麼關係
其他答案更離譜 但這個答案我也想不出來

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。」
