That all slaves would go free.
Marco Polo traveled during the middle ages (AP period 3), for this the communication technology was not very advanced and Western Europe didn't really know the situation of East Asia and vice versa. When Marco Polo explained his travels to the Europeans of the greatness of China many Europeans decided to go and see for themselves if this greatness was indeed true. When the Europeans arrived in China they were very impressed and a new promotion of travel to China emerged, INCREASING China's economy.
The correct option is "Andrew Jackson favored a strong nationalistic foreign policy along with the belief that states should be reponsible for internal solutions."
Andrew Jackson was an American statesman, seventh president of the United States (1829-1837). Jackson was born at the end of the colonial era somewhere on the unmarked border of North Carolina and South Carolina. He came from a newly emigrated Scottish and Irish middle-income family. During the War of Independence of the United States, he served as a messenger to the revolutionaries. At the age of 13 he was captured and mistreated by the English, which makes him the only American president who has been a prisoner of war. Later he became a lawyer. He was also elected to the congressional office, first to the House of Representatives and twice to the Senate.
As president, Jackson faced the threat of secession from South Carolina by the "Abomination Rate" law, which had been passed by the Adams administration. In contrast to several of his immediate successors, he denied the state the right to secede from the Union and the right to nullify a federal law. The nullification crisis subsided when the law was changed and Jackson threatened South Carolina with military action if the state (or any other state) tried to secede.
In anticipation of the 1832 elections, the Congress, led by Henry Clay, attempted to reauthorize the Second Bank of the United States four years before its title expired. Keeping his word to decentralize the economy, Jackson vetoed the renewal of the title, something that jeopardized his re-election. But in explaining his decision as an ombudsman against rich bankers, he could easily defeat Clay in the election that year. He could effectively dismantle the bank by the time his title was won in 1836. His struggles with Congress were embodied in the personal rivalry he had with Clay, who was of Jackson's displeasure and who ran the opposition from the newly created Whig Party. The presidency of Jackson marked the beginning of the ascendancy of the "spoil system" in American politics. He is also known for having signed the "Indian Removal Act" law that relocated a number of native tribes to the southern region of Indian territory (today, Oklahoma). Jackson supported the successful campaign of his vice president Martin Van Buren for the presidency in 1836. He worked to empower the Democratic Party and helped his friend James K. Polk to win the 1844 election.
To minimize the number of free and slave people in the United States states
A is most likely right because a lot modern European countries get their borders from cultural and linguistic boundaries after old empires like Austria-Hungary, Russia, and Germany split up. Poland, Czechoslovakia, and Slovenia, just to name a few, were ethnic groups without countries before WW1.
B: isn't true, just look at eastern Europe in the 17th century, tons of ethnic groups living in one country. Even with more immigration to the Europe, most immigrants assimilate into European cultures.
C: Although geography can influence political borders to varying degrees, European nations don't strictly follow physical geographic features to my knowledge. There are a lot of borders based off of rivers you can see have stayed the same despite the rivers moving (Serbia and Croatia's border is a prime example)
D: I don't know what 'define' means in this context, but if it means religion and geography are the main reasons Europe get's their borders is just flat out wrong. We already talked about geography, but religion doesn't effect European borders since most European countries are christians and are secular. The only example I can think off the top of my head of religion affecting borders is in Ireland when they separated the protestant north from the rest of the island which was catholic.
Hope this helped you out :)
