That was after having spent about 20 years together with African institutions studying hunger in Africa,  之前的20年，我一直在非洲研究饥饿问题，

　　so I was sort of expected to know a little about the world.  所以大家以为我对世界有些了解。

　　And I started in our medical university, Karolinska Institute, an undergraduate course called Global Health.  在我们的卡罗林斯卡医学院，我开设了一门本科生课程，“全球健康”。

　　But when you get that opportunity, you get a little nervous.  刚开课的时候我还有些紧张。

　　I thought, these students coming to us actually have the highest grade you can get in Swedish college systems 因为来听课的都是瑞典大学的优等生，

　　so I thought, maybe they know everything I'm going to teach them about. So I did a pre-test when they came.  他们或许早已了解我准备教的内容。于是在第一堂课里，我作了一个小测试。

　　And one of the questions from which I learned a lot was this one:  其中有一道题让我受益匪浅。

　　"Which country has the highest child mortality of these five pairs?" 下列5对国家中，哪一个的儿童死亡率高于另一个？

　　I put them together, so that in each pair of country, one has twice the child mortality of the other.  我所选择的配对国家，都是一个的儿童死亡率是另一个的两倍。

　　And this means that it's much bigger a difference than the uncertainty of the data.  因为数据差距很大，因此数据本身的不确定性可以忽略不计。

　　I won't put you at a test here, but it's Turkey, which is highest there, Poland, Russia, Pakistan and South Africa.  今天我不会拿这来考大家，土耳其，波兰，俄罗斯，巴基斯坦和南非。

　　And these were the results of the Swedish students.  这是瑞典学生的测验结果。

　　I did it so I got the confidence interval, which is pretty narrow, and I got happy, of course: a 1.8 right answer out of five possible. 让我高兴的是，5题中平均答对的只有1.8题。

　　That means that there was a place for a professor of international health and for my course. 我这个教授还有这门课，因此都有了存在的必要。

　　But one late night, when I was compiling the report, I really realized my discovery.  但后来有天深夜，当我写总结报告的时候，我突然有了新的发现。

　　I have shown that Swedish top students know statistically significantly less about the world than the chimpanzees. 瑞典大学的优等生们对世界的了解，竟然还不如黑猩猩。
