Explanation:

Question 3

The first Americans (Paleo - Americans) are generally believed to have arrived in North America approximately 12 - 20 thousand years ago. The option of 400 - 800 thousand years ago is incorrect as human presence in the Americas is not that old. 1 - 2 million years ago is too early as there is no evidence of human habitation in the Americas at that time, and 3 - 9 thousand years ago is also incorrect as the initial migration was earlier.

Smallpox was a crucial factor in the Spanish conquest of the Aztecs. The disease, brought by the Spaniards, decimated the Aztec population, including their leaders and warriors, weakening their ability to resist. Native dissension also played a role as some native groups allied with the Spanish against the Aztecs. Persuasion (or luck) in terms of forming alliances and taking advantage of the situation was also important. Inferior Spanish military technology is incorrect as Spanish technology (like guns, horses) was superior. The blessings of God is a non - historical, religiously - framed explanation without historical evidence.

Answer:

A....12 - 20 thousand years ago.
