Answer 1

Before the use of electricity, people commonly had two separate sleep periods during the dark hours.

Step-by-step explanation:

Before the use of electricity for nighttime lighting, it was common for people to have two separate sleep periods during the dark hours. This sleep pattern is known as biphasic sleep, where individuals would sleep for a few hours after sunset, wake up for a short period of time, and then go back to sleep until sunrise. It was a natural rhythm that aligned with the absence of artificial lighting.
