Question 24 asks the passage provides a chronological account of how scientists did what? 2 So let's look back at the passage here. We're going to look at a 3 couple of different aspects to determine what this, 4 what the correct answer to this question is. So, first off you can just 5 see in that first paragraph that they're introducing the idea of an 6 effective camouflage technique, 7 which is later called disruptive coloring. 8 So it says predators to reason, locate their prey by looking for their outlines. 9 So animals with high contrast markings that disrupt telltale edges and create false ones 10 can evade detection. And it also said up here that are not explicitly, 11 but it implies that this is a theory it's not necessarily scientifically 12 tested. And then it says in that third part, 13 that's highlighted there. It remains largely untested until Cuthill Stevens and their colleagues 14 devise an experiment. So basically there's this theory proposed. 15 And then this team of researchers devise an experiment about it. 16 And then you can go on to see some more information. 17 It says they revived interest, 18 but the real insights came when another experiment was devised by Richard Webster and his 19 team. And it says that his team vindicated, 20 they are again. So the theory 21 that they are proposed was proven. 22 And then if we look up at the top, it says the experiment had 23 an obvious shortcoming and then goes on to detail and experiment to kind of 24 address th...
