which of the following contributed to the defeat of Aztecs?

A. Drought

B. enslaved Africans

C. earthquakes

D. small pox ****

Yes.

It is traditionally believed that smallpox was the killer, but recently that hypothesis has been challenged and cycles of drought and rainfall leading to waves of rodents carrying indigenous fevers might be the culprit. See: http://blogs.plos.org/publichealth/2013/07/30/guest-post-what-killed-the-aztecs/

so would the question be up to date or what happen then?

The answer was smallpox so I guess I was right.

The smallpox story was standard until very recently.

To determine which of the following contributed to the defeat of the Aztecs, you should evaluate each option and the historical events surrounding the fall of the Aztec civilization.

A. Drought: Drought could have had a negative impact on agriculture, which would have caused food shortages and economic instability. However, it is unlikely to have been a primary factor in the defeat of the Aztecs.

B. Enslaved Africans: The presence of enslaved Africans did not directly contribute to the defeat of the Aztecs, as they were not involved in the conflict between the Aztecs and the Spanish conquistadors.

C. Earthquakes: While earthquakes could cause widespread destruction and impact daily life, they were not a significant contributing factor to the fall of the Aztecs.

D. Smallpox: Smallpox had a devastating effect on the Aztec population. When the Spanish arrived, they brought diseases such as smallpox that the Aztecs had no immunity to. The spread of these diseases contributed greatly to the population decline and weakened the Aztec military and society.

Based on the historical events, option D, smallpox, was a major factor in the defeat of the Aztecs.
