Farming is a common economic activity around two important rivers in South Asia, the INDUS and the GANGES
Explanation:
Ganges and Indus are two of the major rivers flowing in South Asia. They came into existence a long time ago. These rivers along with the Brahmaputra are known to be the backbone of South Asia in terms of culture and economy. The three rivers have contributed to the rise of the earliest civilizations in history.
Farming is the major economic activity in which these rivers have contributed and still contributing to the present as the soil present around them is very fertile and is ideal for various crops such as Wheat, Rice,Cotton,Sugarcane and Maize. The fertility of the soil is replenished when the rivers are flooded making it ready for next cultivation.
The correct answer is - carving terraced farmlands.
The Incas revolutionized the agriculture in South America by starting to use the carved terraces for production. With this technique, the Incas managed to maximize the arable land area, and to perform farming on places where naturally will be impossible. This method is widely used nowadays, and since the amount of arable land is reducing in the lowlands, it is of great benefit for food production in places that are not suitable for building.
Answer:
A nation-state is a state where the vast majority of the population is comprised of a single ethnic group which also serves as a motivation and reason for the formation of the state.
Explanation:
A nation-state is a term used for the nations where the vast majority of the population is comprised of a single ethnic group, usually over 90%. There are multiple examples of such states around the world, some of which are fully recognized, while some function in practice as such but are not officially recognized by the United Nations. In the first category, we have the likes of Mongolia, Iceland, and numerous island nations in the Pacific, while in the second one we have the likes of Kosovo and South Ossetia.
These nations are often formed on the basis of the distribution of an ethnic group, thus determining the boundary in accordance with where the particular ethnic group is found without interruptions. An interesting case was the recent referendum for independence in Scotland as if it was successful it would have meant the creation of another nation-state. This was carefully monitored by many ethnic groups in the world because they saw it as an opportunity to create their own nation-states.
