the aztec's were well known for their irrgation systems in farming along with their unique way of farming known as three-sister's farming. This allowed maize, beans, and squash to be grown at the same time increasing the number of calories for their people (like a symboitic relatioship). They were into sacrificing people for they believed in a sun god and if they didn't sacrfice someone the sun wouldn't return. They used slaves, traitors, theifs, or stole people from other tribes. They had their own language, but as far as mathmatics that didn't really come till later in the greeks time and Europe when that really took off. However, they did create stone tools, arrows, and baskets to help them in their farming and hunting. They had stone arrow heads for maximum force. But new tools and such didn't really come until the columbian exchane with other europeans. They were the strongest empire in the New World and were well-known as hunters and gathers.

Answer:
The United States attempted to halt the communist revolution in Cuba by <u>weakening its economy to force cooperation.</u>
Explanation:
Before the emergence of Fidel Castro and his Communist regime in Cuba, the South American nation had good relations with the United States. Many Americans traveled to Cuba for holidays and even stayed there for years, and there were many other developments and good relations between the two.
But with Castro in power and the Communist revolution, the relationship deteriorated. Cuba was adamant to be a communist country, prohibiting American power or government to interfere in its affairs. But rather than just give up and ignore Cuba, the US decided to attack from non-military angles (for America had been defeated by the Cuban army in the Bay of Pigs invasion). America began restricting its citizens from doing any business with Cuba, prohibiting economic transactions which weakened the economy. This led Cuba to co-operate as there were no other options.
Thus, the correct answer is the first option.
