Common tragedy 的一道题 下列哪一种物品可以类比鱼 a.//////(某种私有产品) b.用太阳能板收集的阳光 c.music broadcasted through public airway d.air above North America e.a specific corporation's 某种矿藏作者选E,大家斟酌,在下面留言 有个题我选的跟有个寂静人不同 D选项是XX上空的AIR E 选项是说一个specific的什么项目 我这个选D 当时脑子短路觉得SPECIFIC的那个项目的产品是不是不可再生啊 不记得了。。 现在想想这个应该错了 不确定 我google到common property(共有资源)和open-access resource(无主资源)的定义(from wiki) "commons" refers to the environmental asset itself, "common property resource" or "common pool resource" refers to a property right regime that allows for some collective body to devise schemes to exclude others, thereby allowing the capture of future benefit streams; and "open-access" implies no ownership in the sense that property everyone owns nobody owns. 感觉E有可能是对的 -- by 会员 加菲猫猫 (2010/5/12 20:19:41)
