question 2

Explanation:

For Question 1, sleep debt is defined as the chronic deficiency in sleep. Jet - lag is due to crossing time zones, rotating shift work can cause sleep issues but isn't the term for chronic sleep deficiency, and circadian rhythm is the body's internal clock.
For Question 2, light - dark exposure is a well - known factor that can help reset the biological clock. Coffee and alcohol consumption can affect sleep but not reset the clock, and napping is a sleep behavior not a way to reset the clock.
