Answer 1

Explanation:

Hunter-gatherers chose to live in caves and rock shelters because they provided them protection from the rain, heat and wind.

(b) Grasslands developed around 12,000 years ago.

When people grow crops they have to have to stay in the same place for a long time to take care of the plants by watering, weeding, driving away animals and birds and finally storing the grains after harvesting. 

mark me as brainliest

Archaeologists found the bones of many wild animals such as deer and pig at the earlier levels. This was used as evidence that many people who lived in Mehrgarh were hunters to start with. But later on, herding became important for them as bones of sheep and goats were found at the later levels.
