Everybody begins to move around, and your task is to keep track of who had a coat at the beginning and who didn't. So I'm just going to show you an example where there is only one sad kid. It's easy because you can actually track it with your eyes. You can track, you can track, and then when it stops, and there is a question mark, and I ask you, did this kid have a coat or not?
Todos empezan a moverse, e a súa tarefa é identificar aos que tiñan abrigo  ao comezo e aos que non. Voulles poñer un exemplo no que só hai un neno triste. É doado, poden seguilo coa vista. Ségueno e, cando para,  aparece unha interrogación e pregúntolles: este neno levaba  ou non o abrigo?
