The correct answer is D) All these answers are correct.
The ancient history of the Americas is not as easily understood as that of India and China because we know of the peoples from their artifacts, there were more varieties and numbers of cultures in the Americas, and written records were not kept.
The ancient civilizations of the Americas left some records in rocks and archeologists have interpreted some information through some artifacts they have found in excavations. However, most of those carved in stone representations have not been interpreted because of their difficulty. We are talking about ancient American civilization such as the Toltecs and the Olmecs in southern Mexico. There is such limited information about them that little is known about their lives.
Much more is known about Mesoamerican civilizations such as the Aztecs. But if we refer to the Mayas, most of its messages left in the Mayan stelae have not been interpreted.

Answer:
The loss of farms during the Great Depression.
Explanation:
This phenomenom known as the "Dust Bowl" was one of the worst ecologic disasters of the 20th Century. During 1930's (and up to 1932 and 1939) droughts affected the plains and meadows extending from the Gulf of Mexico to Canada. The Dust Bowl effect was produced by persistent drought conditions, favoured by years of soil manipulation that left it vulnerable to the effects of wind. Since its humidity levels were almost zero, soil was lifted up by the wind in the form of big sand and dust clouds. The Dust Bowl multiplied the effects of the Great Depression in the zone and caused the greatest displacement of population during a short period of time in United States' history. Three million inhabitants left their farms during 1930's, and more than half a million emigrated to other States, especially to the west.

Explanation:
Vietnam War also called Second War of Indochina, was a war fought between 1955 and 1975 to prevent the reunification of Vietnam under a socialist or communist government. In this war the Republic of Vietnam (South Vietnam) participated, which was against the communists, with the support of the United States and other allied nations of the United States against the local guerrillas of the National Front for the Liberation of Vietnam ( Viet Cong) and the Army of the Democratic Republic of Vietnam (North Vietnam), backed by China and the Soviet Union.
The battles that took place during the conflict occupied the entire territory of Vietnam, the main characteristic of these battles is that they occurred in an area of dense forests, full of natural elements and animals that made the operation of the army of the USA difficult. We could say that this factor greatly favored the army of North Vietnam, since they knew the battlefield perfectly.
