I think we've gotten a good overview, because when you're looking at it with the best science.... Science always evolves. We had this meeting in 2014, and even though we can't prove negatives, by taking a look at things.... That's why we deal with null hypotheses in things like this, and with probabilities. I want to thank you for that.
In my last minute or so, I know that Ms. Harder had a question that she wanted to ask the witnesses as well.
