Answer:
b. False
Step-by-step explanation:
"Mesoamerica" (Middle America) refers to the ancient civilization of Mexico and Central America. This included the Aztecs, Mayans, Olmecs, Zapotecs, Mixtecs and Teotihuacans.
These civilizations were able to independently survive on their own by using advanced techniques. For example, the Mayans made a system of calendar known as "Maya calendars." This is because they were attracted to the cycle of time. Another example are the advanced tools made by the Aztecs. They were even able to make drills (bone and reed). Their agricultural systems were very complex.
