The 2 ideas that thinkers in the US thought were contained in the US Constitution are:
- 1) "Limiting the Powers of State Governments": The state should have legitimate power, in other words, a power that is representative and consented by the people to whom this state governs. People are free to do whatever is not prohibited by the law.
- 4) "Linking Governments and Citizens through a social contract": The <em>"Theory of the Social Contract"</em> is based makes a distinction between <em>civil society</em> and <em>state</em>. The state´s authority is based on the power consented by the people who are governed, which confirm the civil society. A person enters into civil society to protect their rights by contacting an unbiased authority such as appealing to a court.
B) Sam Houston
Sam Houston (1793-1863), as an American soldier and politician, was the one in charge of leading the Texas militia to the battle of San Jacinto (April 21, 1836) and gaining the victory, even though their army was almost half the size of the Mexican's army led by General Antonio Lopez de Santa Anna. The Texans took as prisoners hundreds of Mexicans including, Santa Ana, which in exchange of his freedom, he signed a treaty recognizing Texas’ independence.
After the triumph, Houston was elected as the first President of Texas.
I'm not sure 100% what exactly this question is asking, but I know World War 1 was the first war to include Gas masks and Chemical warfare, so that is more than likely the answer.
