Answer 1

any choices?

Answer 2

A)pyramid structures to show religious figures
B)the Nahuatl language for formal communication
C)a written calendar with religious observances
D)a numerical system organized by tens

Answer 3

The entire span of territory from the U.S. Great Basin
south to Tenochtitlan (The Aztec capital that became Mexico City) was populated
by speakers of Uto-Aztecan languages and dialects. The Spanish always
traveled with Indigenous servants and slaves who spoke many languages. Also,
the time period between the establishment of the Aztec state and the arrival of
the Spaniards spans only a few hundred years, not a long time when it comes to
language change.

So I think the answer is B
