题目是不够严谨。。。这个答案应该是 1!
建议把条件改成:
假设小白鼠喝了毒药后会在一个小时内死亡。 问:要在一个小时内(<= 1 hour)检测出有毒的瓶子, 最多需要牺牲多少只小白鼠?
这样吧,为了对每只小白鼠生命的尊重和公平,每只小白鼠只能实验一次。

I think one is more than enough. The question didn't say the poison would have to "kill" the mouse. It only said assuming the bottle is big enough. Enough for what? Why do I have to assume we would put the mouse in it? why can't I take a drop of it out of the bottle and feed it. If it is not water, the mouse won't like it. It may not even kill the mouse ... if the mouse didn't like it, it probably IS poison.
