english: So this is what they were going to do in their trial: They were taking 3,000 children, they were going to give them these huge fish oil pills, six of them a day, and then, a year later, measure their school exam performance and compare their performance against what they predicted their exam performance would have been if they hadn't had the pills.
non_english: Zo gingen ze tewerk bij hun proef. Ze namen 3.000 kinderen. Die kregen allemaal van die enorme visoliepillen, zes per dag. Een jaar later maten ze hun examenprestaties en vergeleken hun prestaties met wat zij voorspelden dat hun examenprestaties zouden zijn geweest als ze de pillen niet hadden gekregen.
