This has some benefits-- I have them do their in - class writings on the computer and print them straight out . But it also has some drawbacks-- you ca n't exactly drag computer desks around , so we ca n't move into a circle for class discussion . When we do have discussion , I make them move their chairs into the center aisle , where they create some sort of ovalesque blob . It 's not ideal-- people on opposite sides of the blob have a hard time seeing / hearing each other , but it 's better than having them at their computers .

Give answer the following question using evidence from the above passage: Why do the people drag their chairs across the room when the narrator asks them to ?
They dragged the chairs because the narrator is their teacher .
