1- The correct answer is A. Samuel Houston was the Texan leader who most supported the annexation to the United States. In fact, he was President of the Republic of Texas twice, and from his position he always fought for annexation, unlike others like Mirabeau Lamar. In addition, it is stated that Houston went to Texas sent by President Andrew Jackson to achieve annexation.
2- Houston argued that the annexation had to be carried out to respect the will and right of the Texan people (which were made up of American settlers) to decide the legal status of their territory. This argument is related to the right of self-determination of peoples, which I consider valid since it's theb population who has the power to decide on their future and that of the territory they inhabit and administer, not being the states able to make decisions contrary to the people and their will.
Here you don't actually need to fully solve it to know the answer, because it is multiple choice. Just ignore the fractions and subtract the whole numbers: 8 - 13 = -21. So, the answer will be -21 and then a fraction. Looking at the answer choices, A matches this. So, A is the answer
Number 9 Is: 156 And 10 Is: 15 Hours, 900 Minutes
