A. pastoral nomadic
The Mongols were a nomadic tribe, who lived in gers in the steppes of what is now Mongolia. A nomadic pastoral lifestyle is when nomadic peoples travel with livestock, which helps them graze the land, on where these livestock would live. These live stocks are usually herded. Since the steppes of Mongolia are barely arable, pastoral nomadic lifestyle is key, as it is a search for land which is able to feed the people and the livestock. Forty percent of the population in Mongolia still lives a nomadic lifestyle.
