Final answer:
Chinese immigrants followed more formal marriage practices compared to other groups such as colonists in the Middle Colonies, Europeans, and Mexican Americans. In the context of Texas, American settlers differed from tejanos mainly in being slave owners and being religiously distinct, not in advocating for popular sovereignty for all including women.
Step-by-step explanation:
Informal Marriage Among Various Groups
When examining the groups among which informal marriage was common in history, we find that colonists in the Middle Colonies, Europeans, and Mexican Americans all had instances of such informal unions. However, it is well documented that Chinese immigrants adhered to more formal and traditional practices related to marriage and family. This pattern can be attributed to strong cultural traditions that the Chinese maintained, even when arriving in the United States during the late 19th and early 20th centuries.
Tejanos versus American Settlers in Texas
The American settlers in the Mexican province of Texas were typically unlike tejanos in that many were slave owners and they remained religiously distinct from the Roman Catholic tejanos. These differences created a distinct divide between Tejanos, who were residents of Spanish or Mexican descent, and the incoming Anglo-American settlers. It is important to note that these settlers did not typically advocate for popular sovereignty including women, so the correct answer to this question is option d, A and B.
