Things seem to happen for a reason. People usually want to know the reason. The reason why things happen is called a cause. Suppose you fall off your bike. You want to know why. So, you try to find out the cause of your fall. Maybe you hit a big bump on the sidewalk. It is the same in stories and pictures. You try to guess or infer why something happens. You try to find out the cause.
