Final answer:
The claims about Texas land grants made by Mexico being primarily in east and central Texas, the cultural and economic differences between American settlers and Tejanos, the territorial loss for Mexico from the Treaty of Guadalupe Hidalgo, and the motivation behind early U.S. Indian policy centering on land acquisition are all true statements supported by historical evidence.
Step-by-step explanation:
The information provided in the question suggests that the statement about Texas land grants made by Mexico is true. The 1833 map mentioned indicates that nearly all land grants to American settlers were indeed located in the eastern portion of Texas, closer to the United States, which was a strategic move by Mexican officials who wanted to settle areas adjacent to the U.S. to fortify the region and counterbalance the influence of nearby American territories.
Regarding the differences between American settlers and Tejanos in Texas, the correct answer is D. A and B. American settlers were typically unlike Tejanos in that they were often slave owners and they remained religiously distinct from the Roman Catholic Tejanos. This cultural and economic division contributed to tensions leading up to the Texas Revolution.
Concerning the Treaty of Guadalupe Hidalgo, the statement that Mexico lost more than half of its territorial land mass as a result of the treaty is true. This significant land cession included regions that would become part of the present-day southwestern United States.
Lastly, the statement regarding early U.S. Indian policy suggests that the acquisition of land was the most important motivating factor, which is true. The drive to acquire more land for settlement and expansion greatly influenced policies impacting Native American peoples.
