The correct answer is: All of the above.
Assam is a state in north-eastern India. It is a land of great natural beauty, with lush forests, mighty rivers, and snow-capped mountains. However, the harsh climate and difficult terrain have made it difficult to study the state’s prehistory.
The climate in Assam is tropical, with hot, humid summers and cool, dry winters. The average temperature ranges from 20°C to 30°C, but can reach up to 40°C in the summer. The humidity is high throughout the year, and the monsoon rains can be heavy. This climate has made it difficult for archaeologists to find and preserve evidence of human habitation.
The terrain in Assam is also challenging. The state is located on the eastern edge of the Himalayas, and is crisscrossed by rivers and mountains. This makes it difficult to access many areas, and has hampered archaeological research.
In addition, there is a lack of written records from Assam’s prehistory. The earliest written records from the state date from the 7th century AD, and are written in Sanskrit and Assamese. These records provide some information about the state’s history, but they do not provide a complete picture of its prehistory.
As a result of these challenges, our understanding of Assam’s prehistory is limited. However, archaeologists are continuing to work in the state, and new discoveries are being made all the time. It is hoped that one day we will have a complete picture of the state’s long and rich history.
Here is a brief explanation of each option:
- Harsh climate leading to poor preservation: The climate in Assam is tropical, with hot, humid summers and cool, dry winters. The average temperature ranges from 20°C to 30°C, but can reach up to 40°C in the summer. The humidity is high throughout the year, and the monsoon rains can be heavy. This climate has made it difficult for archaeologists to find and preserve evidence of human habitation.
- Difficult terrain in some areas: The terrain in Assam is also challenging. The state is located on the eastern edge of the Himalayas, and is crisscrossed by rivers and mountains. This makes it difficult to access many areas, and has hampered archaeological research.
- Lack of written records: In addition, there is a lack of written records from Assam’s prehistory. The earliest written records from the state date from the 7th century AD, and are written in Sanskrit and Assamese. These records provide some information about the state’s history, but they do not provide a complete picture of its prehistory.
