The owners of a waterpark are taking a survey to determine how many trips to the park kids in the area take during the summer. They take a survey of kids entering the park on a Monday. Is this a good sampling method?

A) No, they should have surveyed kids at the local high school.
B) Yes, because those kids who come on Monday more than likely come on other days, too.
C) No, many area kids may not come to the water park, they need a random sample of area kids.
D) No, they should have surveyed kids on Friday and Saturday when more people come to the park.
