Question

what did he just say could make you a better student?
fighting against gravity
getting your heartbeat elevated on a regular basis.
do what you want to do
becoming a resource hog

Explanation:

To determine the correct answer, we analyze each option: "fighting against gravity" and "becoming a resource hog" are non - sensical in the context of becoming a better student. "do what you want to do" is not a proven method for academic improvement. However, regular physical activity (which elevates the heartbeat) is known to have positive effects on cognitive function, focus, and overall academic performance, so "getting your heartbeat elevated on a regular basis" is the most logical choice.

Answer:

B. getting your heartbeat elevated on a regular basis.
