V. Read the text carefully, then choose the correct answers. For 3,000 years, Mongolians have lived in the rural areas, adopting a pastoral way of life, moving in the search of new pastures. They depend largely on their livestock for a living and sustain themselves with what they can get from the land. Today, approximately half of Mongolia’s population is still roaming the vast plains living in the ger and moving their campings several timesa year. Nomadic life thrives in summer and survives in winter. When temperatures are warm, they work hard on their farms to get milk and make airag, consuming meat from their sheeps and goats. Once winter comes, temperatures dip extremely low and they stay indoors and survive on horse meat. With the rise of technology, changes in the Mongolian nomadic lifestyle are almost inevitable. While they still lead their lifestyle as pastoral herders, many use motorbikes to herd cattle and horses. To move their homes, trucks have taken the place of ox carts. Solar panels are also becoming an addition to the ger, giving them access to electricity without being confined to one place. The nomads use solar energy to power television sets and mobile phones. 1.
