听力原文: Mechanized carnival attractions draw big crowds at the Maryland State Fair. But there is another side to this event. It is a scene that looks like it is fight off the farm. The fair is a yearly event that helps America's largely urban-dwelling population reconnect with its agrarian roots.
Fairs were originated hundreds of years ago in various forms and certainly the fair as we know it is about a hundred years old. It was a place for the agricultural community to get together and show off what they had done over the past year.
Farmland scenes like this have become ever less common across the United States. But it seems they will always be preserved at America's state fairs.
Which of the following statements is correct?
A.The Maryland State Fair is held annually.
B.The Maryland State Fair is held by farmers.
C.The fair as we know it has a long history of hundreds of years.
D.Fairs were originated a hundred years ago.
