Three ways Paleolithic hunter-forager groups used fire

The correct answer is:

1. to stay warm in colder temperatures

2. to cook and prepare food

3. to scare wild animals

Explanation:

To stay warm in colder temperatures: during the days with colder temperatures they needed some source of heating, so they used fire to warm up and protect themselves from freezing.

Cooking and preparing food: while cooking food on the fire, Paleolithic hunter-gatherers were preventing some diseases that the consumption of raw food could cause.

To scare wild animals: in the Paleolithic era, wild animals were a serious threat for hunter-forager groups; they might take their food or attack their camps, so they used fire to scare them away and protect their communities.
