Question

in his argument in favor of starting classes later in the morning, joão is addressing the counterclaim that classes should not start later because doing so would limit students opportunity to participate in school sports and clubs.
although starting classes later might well make it impossible for students to spend as many hours on after-school sports, getting more sleep would ensure that they got more out of the time they did spend on those activities. with more sleep, their sporting performance would actually improve.
which evidence would best support joãos rebuttal?
select three options.
□ sleep deprivation harms memory.
□ overtired teens are more prone to accidents.
□ researchers do not know why human beings need to sleep.
□ sleep deprivation has been used as an interrogation technique.
□ teens dealing from sleep deprivation lose the ability to focus.

Explanation:

João's rebuttal argues that later classes (and more sleep) improve students' performance in the limited time they have for sports/clubs, countering the claim that later classes harm sports/club participation. To support this, we need evidence linking more sleep to better cognitive/physical function that boosts activity performance:

1. "Sleep deprivation harms memory" shows lack of sleep impairs mental function, so more sleep (from later classes) would enhance memory for sports/club tasks.
2. "Overtired teens are more prone to accidents" indicates tiredness (from early classes) increases risk, so more sleep reduces accidents and improves safety/performance in activities.
3. "Teens dealing from sleep deprivation lose the ability to focus" demonstrates sleep loss reduces focus, so more sleep restores focus, making time spent on sports/clubs more productive.

The other options are irrelevant: researchers not knowing why we sleep does not support the link to performance, and sleep deprivation as interrogation is unrelated to student activity performance.

Answer:

• Sleep deprivation harms memory.
• Overtired teens are more prone to accidents.
• Teens dealing from sleep deprivation lose the ability to focus.
