1. what impact does exercise have on academic performance?

a person who exercises is more likely to earn higher grades, but only in math and art courses.
exercise improves physical health and mental health, but it does not impact cognition
a person who exercises is more likely to earn higher grades.
a person who exercises is more likely to earn lower grades.

Explanation:

Question 1

To determine which skill people can learn 20% faster after exercising, we analyze the options. Vocabulary involves memory and cognitive processes, and research suggests exercise can enhance cognitive functions like memory, aiding faster vocabulary learning. Math, History, and Culinary skills have less direct evidence of a 20% faster learning rate post - exercise compared to vocabulary - related cognitive improvements.

We evaluate each option. Option 1 (impact only in math and art) is too limited. Option 3 (no impact on cognition) is incorrect as exercise is known to impact mental health and cognition. Option 4 (lower grades) is wrong as exercise generally has positive effects. Option 2 states that exercise improves physical and mental health, and a person who exercises is more likely to earn higher grades. This aligns with research showing exercise boosts cognitive function, focus, and overall well - being, which supports better academic performance.
