Answer 1

From the information I withdrew from your text. The answer would Be B. The sample might not be representative of the population because it only includes student who are attending an after-school activity. Mainly because you can't determine the amount/percentage of people who ride the bus 'to' school by asking people who take after school programs.
I hope this helps ^-^

Answer 2

The answer is B because it only represents 200 students who are attending an after-school activity.
