So now here's a question: if I were to ask you, for example, to make a one-time investment of, say, 200 million dollars to buy one of those bottles, so 200 million dollars up front, one time, to buy one of those bottles, I won't tell you which one it is, and in 10 years, I'll tell you whether you have one of the blue ones.
问题出来了 如果我问你，例如 做一次性的投资 两亿美元 买其中的一瓶药 初始投资两亿，一次性 买其中一瓶 我不会告诉你是哪一瓶 十年后，我会告诉你,你买的是否是蓝瓶的.
