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?
子供たちが動き始めますので 誰が始めにコートを着ていたか 着ていなかったか 見失わないで下さい ちょっとやってみましょう 悲しそうな子は一人だけなら 実際に眼で追えるので これは簡単です 映像が止まって はてなマークが付きました この子はコートを着ていましたか？
