Answer to Question 2
Answers will vary but can include the following pros and cons: Research on
adolescent brains has shown that starting school later in the morning more closely
follows the adolescent's normal sleeping and waking pattern and results in teens
being less likely to fall asleep in class and more able to learn. However, many
parents and other adults have their own reasons for wanting school to start earlier:
bus drivers don't want to drive in rush hour traffic, cafeteria workers want to be
home earlier, coaches want after-school activities to end before dark, etc.
