In the novel 'Lord of the Flies' by William Golding, Ralph chides the boys for a breakdown of the order they thought they had created at the last meeting. He had thought that the positive mood to get things done would prevail so that they could keep themselves healthy and safe until they got rescued. Everyone was to have a job - a part to play in building shelters and a safe healthy environment. But now he finds no-one is sticking to it except himself and maybe a couple of others like Simon. He chides the boys for failing to keep the fresh water supply going and abandoning the makeshift latrines. He chides the littleuns for giggling, falling off logs and benches and larking around. He details exactly who contibuted to building which shelter. The meeting is just another disappointment,however.
At the meeting in Chapter 5, Ralph scolds the boys for a lot of things. In general, he scolds them for being irresponsible. You can look at the question just before this one for a list of things that he is upset about.
At the meeting, the kids end up being very afraid about the beast. Ralph and Jack had been trying to convince them that there was no beast on the island. But then Percival says that the beast lives in the sea. After that, the kids are very afraid. They are convinced that the beast is real now, because it could very well be out in the ocean.
