#### Unscramble the Blue Letters

I started to learn some of these when I was working in a statistical dnmatperet that's part of the United Nations. Our job was to find out how many Iraqis had been forced from their homes as a result of the war, and what they needed. It was really important work, but it was also indirlcbey difficult. Every single day, we were making decisions that affected the accuracy of our numbers â diiecnoss like which ptars of the country we should go to, who we should speak to, which questions we should ask. And I started to feel really douliseilnisd with our work, because we thought we were doing a really good job, but the one gruop of people who could really tell us were the Iraqis, and they rarely got the chance to find our asnialys, let alone quositen it. So I started to feel really determined that the one way to make numbers more accurate is to have as many people as possible be able to question them.

#### Original Text

I started to learn some of these when I was working in a statistical department that's part of the United Nations. Our job was to find out how many Iraqis had been forced from their homes as a result of the war, and what they needed. It was really important work, but it was also incredibly difficult. Every single day, we were making decisions that affected the accuracy of our numbers â decisions like which parts of the country we should go to, who we should speak to, which questions we should ask. And I started to feel really disillusioned with our work, because we thought we were doing a really good job, but the one group of people who could really tell us were the Iraqis, and they rarely got the chance to find our analysis, let alone question it. So I started to feel really determined that the one way to make numbers more accurate is to have as many people as possible be able to question them.
