Question

Manjit is writing an argumentative essay to support her claim that her high school should not start classes before 9 a.m. This is one of her reasons.

Teenagers learn better if they have had enough sleep.

Which evidence best supports the reason?

Teenagers who are tired are often tardy or fall asleep in class.
If students start school later, it could make parents late for work.
Students should go to bed earlier so they will not be so tired in the morning.
Teenagers who start school later might not have time for after-school sports.

Answer 1

"Teenagers who are tired are often tardy or fall asleep in class."

Explanation: This directly shows how lack of sleep interferes with learning (missing instruction, reduced attention). The other choices are unrelated or argue against later start times.
