At that time, major agricultural produces were several grain bearing grasses including wheat, barley and rice grew naturally in different parts of the sub-continent. Men, women and children probably collected these grains as food and learnt where they grew and when they ripened.

Archaeologists have found blocks of stone tools that were made and perhaps discarded because they were not perfect and chips of waste stone left behind at these sites.
So, from these evidences, the archaeologists knew about the factories.

For various purposes, stone tools were used like:
(i) To cut meat and bone.
(ii) To scrape bark from trees.
(iii) To scrape hides (animal skins).
(iv) To chop fruit and roots.
(v) To make spears and arrows for hunting.
(vi) To chop wood for firewood and to make huts.

It was difficult for hunter-gatherers to collect food as:
(i) As there were several animals that ran faster than human beings and they were stronger also.
(ii) People do not know about the edible part of the plant.

The hunter-gatherers used fire for the purposes like:
(i) as a source of light.
(ii) to cook meat.
(iii) to scare wild animals Yes, fire is still in use as a source of light in villages and as well as in cooking food.

(I) The hunter-gatherers travelled from one place to another in search of food.
(ii) Sometimes they followed the animals who were also moving from place to place in search of their foods. For example, smaller prey, grass and leaves etc.
(iii) The hunter-gatherers often moved from season to season in search of different seasonal plants.
(iv) Sometimes they moved in search of enough sources of water for their survival. The movement of hunter-gatherers were totally based on their basic needs, mainly food and water. This is quite different from the reasons for which we travel today. Now we generally travel for official responsibility, exploring the new lands or personal reasons. We are not travelling in search of food. But poor sections of our society are often migrating in search of their livelihood, which can be described as in search of food also.

The beads could have been used for making ornaments and jewelleries.

The term Neolithic means a New Stone Age, which was period in the development of human technology, beginning about 10,000 years ago.

Today, we use fire:
(i) to cook food.
(ii) as a source of light.
(iii) as a source of heat in winter season.
(iv) in industries, mills ere.

(i) The tools (A) were used for:
1.grinding the grains.  
2.making of tools.
(ii) The tools (B) were used for:
1.cutting meat.
2.chopping fruits.
(iii) The tools (C) were used for:
1.digging soil.
(iv) The tools (D) were used for:
1.hunting animals.
(v) The tools (E) were natural pebbles which were also used for:
1. grinding grains.

There were major changes in the climate of the world. Climate became relatively warm than the past. This warm condition led to some major changes:
(i) There was development of grasslands in many areas. As a result, the number of animals, which survived on grass, was increased. These animals were deer, antelope, goat, sheep and cattle.
(ii) This increasing number of animals helped people to start thinking about herding and rearing of these animals. Fishing became important.
(iii) At that time, several grains bearing grasses like wheat, barley, rice grew naturally and men became aware about where these grew and when they ripened. These grains were collected by men, women and children and they started thinking about growing these plants on their own.
