Last night, Sam and his sister watched a new TV program called City Detectives. It is a mystery show about two friends who solve small crimes in their town. The episode started at 8:00 p.m. and the story was easy to follow. Sam liked it because it was exciting but not scary. His sister liked the main character because she was smart and funny. During the show, there were short breaks for advertisements, so they went to the kitchen to make tea. At the end of the episode, the detectives found the missing bike, and Sam wanted to watch the next episode right away. His sister agreed, but their parents said they had to turn off the TV and go to bed because it was already late.
Why didn’t they watch the next episode?
