Anyway since editing is the main problem, what we're going to do this afternoon is, actually, I'm going to show you another video and again it's a very controversial one, again it's used in, in teaching situations, again it has a biased point of view in the sense that it's produced by National Power, er clearly as a P R job for introduction into schools erm and I want you to do the same exercise, but this time I want us to edit them among ourselves and  what I'm going to do is to get you to wri write your reviews and then we'll divide into small groups, while you're watching it I'll co I'll count how, however many people we've got here, we'll copy the reviews and in the same groups I want you to edit one another 's reviews and then er discuss them within the groups once you've, once you've marked them so we'll get into the small, we'll do the review  we'll write the review and then we will er, I distribute the, you can go and have a cup of coffee while we copy them, then we'll distribute them, you can mark them, er individually on your own and then we'll get into a group and you can criticize one another 's reviews, we'll take them one at a time, we'll probably be in groups of four, okay, but I'll see, I'll see how many, what the most suitable number is, okay so, if you, would you be kind enough to  that
