Final answer:
The Tigua and Jumano differed from other Texas natives due to (option A) their adobe houses. American settlers in Mexican Texas also differed from tejanos because many were slave owners and were not Roman Catholic.
Step-by-step explanation:
The Tigua and the Jumano were different from the other native inhabitants of Texas because (option A) their houses were made from adobe. Adobe is a building material made from earth and organic materials, which was a common form of architecture for various indigenous groups in the American Southwest, including those in New Mexico and Arizona. Among the Pueblo peoples, multistory structures similar to modern apartment complexes were constructed from adobe, indicating a distinct architectural tradition separate from other Native American cultures in Texas that did not typically use adobe for building.
Regarding the American settlers in the Mexican province of Texas compared to tejanos, they were typically unlike tejanos in that many were slave owners and they remained religiously distinct from the Roman Catholic tejanos. This cultural and religious distinction was compounded by the practice of slavery among the settlers, marking a clear difference in societal practices and beliefs.
