B. the cultivation of tobacco
I think the correct answer from the choices listed above is the third option. The key belief or practice in the aztec religion would be noblemen sacrificed their first-born sons at the temple. Hope this answers the question. Have a nice day. Feel free to ask more questions.
You could start off with the news report about how Soviet and U.S almost started another war due to a missile crisis with Cuba or how soviet's government is different from ours. Basically compare and contract Soviet and U.S.
Hopefully this can get you a head start
Have a great day :)
