How were slaves used by the maya and the aztecs?

slaves could buy their freedom after serving for two years.
slaves could work toward owning a portion of the land.
slaves were not allowed to eat the crops they worked.
slaves were sometimes used as a sacrifice to the gods.

I believe the answer is D.Slaves were sometimes used as a sacrifice to the gods.

the catholic church withhold people's access to the bible during the middle ages.

people could go to church and listen to the teachings, but it was absolutely forbidden to own and/or read the books of both the old and new testaments. it was also prohibited to translate the books (which where originally in biblical hebrew) to any other language.

this was done so the church could remain in control of what their teachings were and to enhance their importance and power, while also being able to judge people's actions through information that was unavailable for the general public.
