Challenges in studying Meghalaya’s prehistory include:

Limited archeological excavations
Difficult terrain and dense forests
Degradation of artifacts due to climate
All of the above

The correct answer is: d) All of the above.

Meghalaya is a state in northeastern India. It is known for its beautiful scenery, including its many hills and forests. However, the terrain in Meghalaya is also very difficult to access, which makes it challenging to conduct archaeological research. In addition, the climate in Meghalaya is very humid, which can cause artifacts to degrade quickly. As a result, there are many challenges in studying Meghalaya’s prehistory.

Here are some additional details about each of the challenges mentioned in the question:

  • Limited archeological excavations: Meghalaya is a large state, and only a small portion of it has been excavated by archaeologists. This is due in part to the difficult terrain, which makes it difficult to access many areas of the state. In addition, the state government has not always been supportive of archaeological research, which has also limited the amount of excavation that has been done.
  • Difficult terrain and dense forests: The terrain in Meghalaya is very rugged, with many hills and valleys. This makes it difficult to access many areas of the state, and it also makes it difficult to transport equipment and supplies. In addition, the forests in Meghalaya are very dense, which can make it difficult to find archaeological sites.
  • Degradation of artifacts due to climate: The climate in Meghalaya is very humid, which can cause artifacts to degrade quickly. This is especially true for artifacts made from organic materials, such as wood and leather. In addition, the acidic soil in Meghalaya can also damage artifacts.

All of these challenges make it difficult to study Meghalaya’s prehistory. However, archaeologists have made some progress in recent years. They have discovered a number of important archaeological sites, and they have learned a great deal about the history of the state. However, there is still much that we do not know about Meghalaya’s prehistory, and archaeologists continue to work to learn more.
