Answer:
Options that are true are: were nomadic and developed the use of fire.
Options that are false are built permanent dwellings and irrigated the land.
Step-by-step explanation:
During the Paleolithic period prehistorical hominids weren't much advances. Still, with the invention of fire they were able to prepare food and not to eat it raw, but still due to lack of resources were moving a lot.
On the other side, they didn't have permanent settlements, but were rather living in caves or in the open. They didn't have technological means to develop irrigation. That happened much later.
