The message and the events at the Alamo primarily inspired Texans to fight for their independence. Therefore, the appropriate responses from the options given are:
- It encouraged Texans to plead with the United States for support.
- It inspired Texans to fight the Mexicans for their independence.
The first option regarding discouragement does not apply, as the rallying cry from Travis was meant to inspire and uphold the fight, rather than demoralize. The option regarding enslaved people's desire for freedom, while relevant to broader themes of liberty, is not directly reflected in Travis's message.
