Question

how was francisco pizarro’s conquest of the inca empire affected by the spread of european diseases?
the spread of disease had no effect on pizarro’s conquest.
the inca empire was fully immune to european diseases.
smallpox had already weakened the inca empire, making conquest easier for pizarro.
smallpox weakened the spanish forces, delaying the conquest.

Explanation:

Historical records show that European diseases like smallpox spread rapidly among the Inca population (who had no prior exposure or immunity) before Pizarro's arrival, causing massive deaths and destabilizing the empire. This weakened state directly facilitated the Spanish conquest. The other options are incorrect: disease significantly aided conquest (not no effect), the Inca lacked immunity, and smallpox strengthened Spanish forces indirectly by weakening the Inca, not delaying conquest.

Answer:

Smallpox had already weakened the Inca Empire, making conquest easier for Pizarro.
