参考答案：A

解析：
In New York City, people complained for years about having to recycle their trash. Then they complained when Mayor Michael R. Bloomberg canceled most recycling to save the city money. And they positively howled in confusion when he restored some recycling but cut collections to every other week.

[分析]： 隐含事实的判断。
从原文中纽约人对回收垃圾的态度可知，他们对回收垃圾持抱怨的态度；对市长取消大部分回收项目持抱怨态度，对他恢复对某些垃圾的回收且回收次数改为隔周一次的态度有褒有贬众说纷纭。由此可推测出无论怎么做，都不可能使所有纽约人满意。因此，选项A的说法是正确的。
[解题关键] 掌握某些表态度的关键词有助于得出正确答案，如根据原文 complained和howled in confusion推断出正确答案。
