Some of the lessons are; to educate women and minorities, to have a fair government, to have minimum wage, and they don't need to push all immigrant groups to be Americanized. Another thing that could help the social problems today is to still create fair and safe working conditions at every work site. </span>

1. D. Inca settlements were difficult to find and reach because they were build at high altitudes on rough terrain.
Inca civilizations were well hidden and protected from outside influences due to their location high in the Andes Mountains of South America. It took the Spanish a while to find them, though diseases reached the outlying settlements even when the Spanish did not.
2. D. infectious diseases and drought
The Maya civilization experienced a lengthy and extreme drought that led to widespread starvation, which reduced their population and influence over the region long before Europeans arrived in Mesoamerica. The Inca and the Aztec populations were wiped out by the infectious diseases the Spanish conquistadores brought with them.
