Sofia has a big test and has been studying really hard. Her father comes into her room and suggests that she take a break and go walk outside for 15 minutes. Which BEST explains why this is good advice? A break always helps with studying. It is a good start, but she will need to exercise for at least 30 minutes to get any benefit. Exercise can improve brain function. Since Sofia is a good student, she probably does not exercise as much as she should.
