Question

although cortes had superior weaponry, he was forced to adopt the tactics of the aztecs themselves because:
a they were afraid to demonstrate to the aztecs how firearms were used.
b the humid climate made gunpowder unpredictable.
c his men were not trained to use firearms.
d neighboring native peoples came to the defense of the aztecs.
e they were impressed by the prowess of the aztecs.

Explanation:

Cortes' men faced challenges with gunpowder due to the humid climate. Gunpowder's effectiveness is affected by moisture. In a humid environment, gunpowder could become damp, leading to inconsistent performance. This would make relying solely on firearms (which used gunpowder) unreliable. Adopting Aztec tactics (which likely didn't rely on gunpowder - dependent weapons in the same way) would be a practical solution.

• Option A: There's no historical indication of fear of demonstrating firearm use.
• Option C: Cortes' men were likely trained to some extent in using firearms they had.
• Option D: Neighboring native peoples' defense of Aztecs is not directly related to Cortes adopting Aztec tactics due to weaponry - related issues.
• Option E: Impression of Aztec prowess is too vague and not the key reason tied to weaponry functionality.

Answer:

B. the humid climate made gunpowder unpredictable.
