So let's go back to lines 18 to 33, 3 reread these paragraphs and figure out what they're trying to do. 4 So it starts here and it goes down to here. 5 He and his colleagues set up eight mesocosms each containing five beanstalks. 6 The plants were allowed to grow for four months. And during this time every 7 plant could interact with symbiotic fungi in the soil. 8 Okay. So he's describing how the experiment is set up. 9 Let's see if he keeps doing that. Not all of the bean stocks though, 10 had the same relationship with the fund guy in each mesocosms one plant was 11 surrounded by a mesh penetrate by holes, half a micron across gaps. 12 That size are too small for either roots or high fate of penetrate, 13 blah, blah, blah. And as I just read this quickly, 14 it seems to be just more again, describing the experiments set up for this. 15 So it seems to just be describing the overall setup of the experiment that 16 he's working with. So let's look through his options and tells us what that 17 is says, evaluate the experiments methods. 18 Now, these aren't really an evaluation of the experiments methods. 19 These are telling us what the experiments methods are or the conditions of the 20 experiment that they're setting up, but it's not an evaluation of them. 21 So we're going to put a no for that.
