**Megalithic People and their Lifestyle**

**Introduction:**
The Megalithic people, also known as the megalithic builders, were prehistoric communities that lived during the Neolithic and Bronze Ages. They are best known for their construction of megalithic monuments, such as stone circles, tombs, and standing stones. These structures are found in various parts of the world, including Europe, Africa, Asia, and the Pacific Islands.

**Nomadic Lifestyle:**
The correct answer to the question is option 'a' - Nomadic. Megalithic people were primarily nomadic, meaning they did not have a settled or sedentary lifestyle. They did not establish permanent settlements but instead moved from one place to another in search of resources, including food, water, and grazing lands for their livestock.

**Reasons for Nomadic Lifestyle:**
1. **Hunting and Gathering:** The megalithic people relied on hunting and gathering as their primary means of subsistence. They followed the migration patterns of animals and the seasonal availability of edible plants, which required them to move frequently.
2. **Limited Agricultural Practices:** Unlike later civilizations that developed advanced agricultural practices, the megalithic people had limited knowledge and technology for farming. They practiced a rudimentary form of agriculture, which involved shifting cultivation or slash-and-burn farming. This method required them to clear land, cultivate crops for a few years, and then move on to new areas when the soil became infertile.
3. **Semi-Nomadic Pastoralism:** Some megalithic communities practiced semi-nomadic pastoralism, where they herded animals like cattle, sheep, and goats. They moved their herds from one grazing area to another, following seasonal patterns and the availability of grass and water.
4. **Resource Exploitation:** Nomadic lifestyle allowed the megalithic people to exploit a wide range of resources across different regions. They could access diverse landscapes, including forests, rivers, mountains, and coastlines, which provided them with a variety of food sources, raw materials, and trade opportunities.

**Conclusion:**
The megalithic people lived a nomadic lifestyle due to their reliance on hunting and gathering, limited agricultural practices, semi-nomadic pastoralism, and the need to exploit diverse resources. Their mobility allowed them to adapt to changing environmental conditions and maximize their chances of survival in prehistoric times.

Because they were the people living in Mesolithic period... and they were the people who lived by travelling from one place to other...
