The correct answer is:
A. Smallpox weakened the aztec's ability to resist.
C. The Spanish took Moctezuma prisoner
D. The Aztecs welcomed the Spanish with gifts.
Explanation:
The Aztec Empire was conquered by the Spaniards under the leadership of Hernan Cortes from 1519 to 1521. When the Spanish first arrived to Mexican territory the Aztecs welcomed them with gifts allowing them to enter freely, seeing those splendorous gifts only awakened the interest of the Spaniards in conquering the territory.
The Spanish conquerors had better tactics and new equipment such as guns and cannons, they made alliances with the Aztec's enemies such as the Tlascalans. They were in advantage and Moctezuma was held hostage trying to escape, the Spaniards conquered Tenochtitlan, bringing new diseases like smallpox that killed more than 7 million, this weakened the Aztec population and their ability to resist the invasion.
