01 What is a benefit of sleeping on time?
Answer and explanation
Correct answer: A. It gives rest to the body and mind.
Explanation: Going to sleep at a regular and suitable time allows the body and mind to recover. Adequate rest supports energy, attention, mood, and a healthy daily routine, which can improve the next day’s learning. It does not always prevent study or increase stress; insufficient or irregular sleep is more likely to cause those difficulties. Hence, A is correct.
