Final answer:
One of the requirements for Anglos immigrating to Texas was to convert to Catholicism, a part of Mexico's integration effort, even as many maintained their Protestant faith. They also differed significantly from the Tejanos on the issue of slavery, bringing many slaves into a region where the practice had been largely abandoned. The correct option is b).
Step-by-step explanation:
Among the requirements Anglos had to agree to when immigrating to Texas, one crucial condition was to convert to Catholicism. This was a part of the Mexican government's effort to integrate American settlers into Mexican society.
However, many settlers, while not openly defying this requirement, maintained their Protestant faith and remained religiously distinct from the Roman Catholic Tejanos. The other significant difference between American settlers and Tejanos was in the matter of slavery.
While slavery had become virtually non-existent in Mexico, the American immigrants brought with them hundreds of slaves, taking advantage of Mexican laws that looked the other way to encourage settlement.
The settlement terms were generous, as male colonists were allowed extensive land grants, including additional acreage for their wives, children, and even slaves. The underlying issue of slavery would eventually become a point of contention leading to further political tensions. Option b) is the correct one.
