问题 What have made people certain of the purity of bottled water? [br] According to estimates,what is the recycle rate of water bottles?
选项
答案 Fewer than 20 percent．
解析 根据题干中的according to estimates定位到原文最后一段第三句Yet fewer than 20 percent of them ever make to a second life, according to estimates by the Container Recycling Institute．题目问的是，据估计，瓶装水包装的回收率是多少。原文最后一段第三句提到，据容器循环再造研究所估计，只有不到20%的瓶装水包装成功得到二次利用。题干中的the recycle rate意为回收串，recycle与原文中的make it to a second life相对应，故答案为fewer than 20 percent。
