Answer: Here's all the land pieces I know
Louisiana Purchase: Sold by Napoleon to the US in 1803
Flordia: The Adam-Onis Treaty seceded Florida the US
CA, NV, UT, AZ: Treaty of Guadalupe Hidalgo ended the Mexican-American war and these territories are called the Mexican cession.
Texas: (kinda complicated) Texas won its own independence and became the Lone Star state. Because of slave issues they did not admit Texas for a number of years. The Mexcian-American war did secure a lot of these lands
Oregon Territory: This land was previously co-ruled by Britsh and the US. They wanted this to end so they divided the land in half at the 49th parallel. President Polk tried to push for more land but was rejected.
Gadsden Purchase: Last purchase of land until Alaska or Hawaii. Bought from the Mexican government to build an easier railroad route (avoid tunning through the Rocky Mountains). This is a small portion of land below New Mexico.
You should not leave it out longer than 1/2
The correct answer is extrinsic motivation.
Extrinsic motivation refers to behavior that is driven by external rewards. In other words, the motivation to engage in a behavior arises from the outside sources because it is naturally satisfying to them. Practically, the behavior is driven by a reward given by someone or something else if the particular thing is done correctly. In this example Brenda is motivated to study more because she wants to earn an A, thus a reward for her effort of studying.
Answer:
In the theory of Karl Marx, the term proletariat designated the class of wage workers who were engaged in industrial production and whose chief source of income was derived from the sale of their labour power.
A strength of marxism is that this theory analyses power and conflict in society. It explains why there is such an uneven distribution of power and wealth between social classes.
