Answer 1:
The correct answer is c, priests.
Step-by-step explanation:
Aztec society had two different types of school. The sons of noble lineage attended the calmecac, while sons of commoners were sent to the telpochcalli. While the education provided in the telpochcalli was focused on military training and trades, calmecac students would receive a much more comprehensive education: apart from basic military training, they would be taught how to read and write, and how to perform religious rituals. Priests were literate and tasked with writing religious texts, so they were more likely to record written texts.
Answer:
The Olmecs.
Step-by-step explanation:
Ancient Mesoamerican calendars required the use of zero for their numeral system. These calendars had a base-20 numeral system, which means they counted from 0 to 19 before they started the count over from 0. While most of these calendars are Mayan, they were not the first to use them, as base-20 calendars predate the Maya civilization. Many of the earliest ancient calendars were found within areas inhabited by the Olmec civilization, so it is generally believed the Olmecs were the first to use the zero in Mesoamerica.
