The Aztecs and the Mayans were two ancient societies in Meso America. The Mayan civilization goes back to about 1800-2000 BC and was in decline when the Spaniards arrived whereas the Aztecs were a much younger civilization that was at its peak when Cortez arrived. The Aztecs were located mostly in what is now Mexico whereas the Mayans were more in what is now Guatemala and Honduras. Both the Aztecs and Mayans believed in human sacrifice but the Aztecs did this much more than the Mayans. While the Aztecs layed out their cities according to celestial observances, the Mayans were more scientific and developed a calendar very similar to our modern calendar. The Aztecs had one supreme ruler whereas the Mayans had many city states like Uxmal in Guatemala and Copan in Honduras with local rulers.

A. THE SOVIET UNION is the country that turned down U.S. offer of economics assistance in the Marshall Plan.
The Soviet Union refused the offered aid for the reason that accepting the Marshall Plan would constitute too much foreign interference in their Soviet economy.
The Marshall Plan was created as an American initiative to aid Western Europe after the World War II. This aid will be given after the fulfillment of their set conditions. The conditions were: each country must lay out a four-year plan that explains the procedures the country has to undergo for the intended economic transition; their government must also set aside "counterpart" funds subject to the spending discretion of the U.S. administrators.

Acculturation is an anthropological and sociological concept that is related to the fusion of elements belonging to two or more cultures.
It is determined by a dynamic process of social and cultural change that takes place through the contact (direct or indirect) between different social groups.
These groups are influenced by different elements, and thus, they create new structures. As an example, we can mention the fusion between Greek and Roman culture that generated Greco-Roman culture.
Remember that culture is a very broad concept that involves knowledge, values, customs, ways of doing, practices, habits, behaviors and beliefs of a specific people. It is not static and is therefore in a continuous process of change.
