Pre-Historic Period and Indus Valley Civilisation

During the Mesolithic Age, farming techniques were developed and man began to grow crops. Man also learnt to draw and paint and the evidence is found in the form of cave paintings found in India.
The Mesolithic Age lasted from 8000 B.C. - 4000 B.C.; the Neolithic Age lasted from 4000 B.C. - 2500 B.C.

The Neolithic Age lasted from 4000 B.C. - 2500 B.C. This age also saw domestication of cows, horses and other poultry and farm animals. The wheel, which was a very important invention, was invented during this age.
Shortly after this age around 1800 B.C., tools were made of copper and bronze and were used for many practical purposes. People of Stone Age did not use tools made up of iron.

Bhimbetka is an archaeological World Heritage site located in Raisen District in the Indian state of Madhya Pradesh. The Bhimbetka rock shelters exhibit the earliest traces of human life in India.

The Indus Valley Civilisation (IVC) was located in the western region of South Asia, and spread over what is now Pakistan, northwest and western India, eastern Afghanistan, and southeastern Iran.

Chanu Daro and Kot Diji are found in present day Pakistan.

All of the given features/facts are correctly matched with their respective timelines.

Statement 1 is correct: The Bronze Age is the era when metals were used and improvised for making tools and other weapons. This age came immediately after the Neolithic Age and aided in the development of the metallurgy industry. The Bronze Age in India is roughly estimated to have begun around 3300 B.C. It almost coincided with the beginning of the Indus Valley Civilization.
Statement 2 is incorrect: People living in Indus Valley produced bronze, copper and tin, thus developing new techniques of metallurgy. People of Indus Valley Civilization did not use tools made up of iron.

A harp-like instrument depicted on an Indus seal and two shell objects was found at Lothal and this indicates the use of stringed musical instruments.

In view of the large number of figurines found in the Indus Valley, some scholars believe that the Harappan people worshipped a Mother goddess symbolising fertility, a common practice among rural Hindus even today. However, there were no religious buildings or evidence of the same. If there were temples, they have not been identified.

Harappan society had no rulers, and everybody enjoyed equal status. Ther was no kingship.
The people of the Indus Civilization achieved great accuracy in measuring length, mass, and time. They were among the first to develop a system of uniform weights and measures.

Around 1800 BCE, signs of a gradual decline began to emerge, and by around 1700 BCE, most of the cities were abandoned. In 1953, Sir Mortimer Wheeler proposed that the decline of the Indus Civilization was caused by the invasion of Aryans. Today, many scholars believe that the collapse of the Indus Civilization was caused by drought and a decline in trade with Egypt and Mesopotamia. It has also been suggested that immigration by new peoples, deforestation, floods, or changes in the course of the river may have contributed to the collapse of the IVC.
A possible natural reason for the IVC's decline would have been connected with climate change that is also signalled for the neighbouring areas of the Middle East. A tectonic event may have diverted the system's sources toward the Ganges Plain, though there is complete uncertainty about the date of this event, as most settlements inside Ghaggar-Hakra river beds have not yet been dated. The actual reason for decline might be any combination of these factors.

Ropar is an archaeological site that shows continuous habitation through five cultural phases: Harappan, PGW (Painted Grey Ware), NBP (Northern Black Polished Ware), Kushana-Gupta, and Medieval periods. Excavations at Ropar revealed rectangular mudbrick chambers and unique burial practices including dog burials below human graves, making it the correct answer.

Dholavira was the largest site of the Indus Valley. It was known for its unique water management practices.

The Indus civilization's economy appears to have depended significantly on trade, which was facilitated by major advances in transport technology. The IVC may have been the first civilization to use wheeled transport. These advances may have included bullock carts that are identical to those seen throughout South Asia today, as well as boats.
