Which two items common in Europe did the conquistadores introduce to the people of Mesoamerica and South America?

The answer is that the conquistadors introduced horses and guns to the people of Mesoamerica and South America.

Explanation:

In 1519, when Hernando Cortes arrived in Mexico, he had brought the first horses to the Americas. Hernando Cortes brought 16 horses with him. Other animals that the Spaniards introduced included pigs, goats, sheep, chickens, cats, cattle, donkeys, bees and new dog species.

As the conquistadors conquered and established settlements, they introduced the indigenous people to new technologies and farming methods. The people of the land learned new farming techniques using tools such as plows. The conquistadors built homes, farms, chapels and other buildings using building patterns and designs similar to those in Europe. The soldiers also brought new weapons that helped the indigenous people to fish and hunt with greater ease.
