According to the writings of Vitruvius, the Greek mathematician Archimedes created a primitive elevator in 236 B.C. that was operated by hoisting ropes wound around a drum and rotated by manpower applied to a capstan. In ancient Rome, a subterranean complex of rooms, animal pens and tunnels stood beneath the Colosseum. At various intervals, elevators powered by hundreds of men using winches and counterweights brought gladiators and large animals up through vertical shafts into the arena for battle.
In 1743, Louis XV had what was referred to as a “flying chair” built to allow one of his mistresses to access her quarters on the third floor of the Palace of Versailles. Similarly, a “flying table” in his retreat château de Choisy allowed the king and his private guests to dine without intrusion from the servants. At the sound of a bell, a table would rise from the kitchen below into the dining room with an elaborate meal, including all of the necessary accoutrements.
By the mid-19th century, elevators powered by steam or water were available for sale, but the ropes they relied upon could be worn out or destroyed and were not, therefore, generally trusted for passenger travel. However, in 1852, Elisha Graves Otis invented a safety break that revolutionized the vertical transport industry. In the event that an elevator’s hoisting rope broke, a spring would operate pawls on the car, forcing them into position with racks at the sides of the shaft and suspending the car in place. Installed in a five-story department store in New York City in 1857, Otis’ first commercial passenger elevator soon changed the world’s skyline, making skyscrapers a practical reality and turning the most valuable real estate on its head—from the first floor to the penthouse.

<em>Declining political participation as a result of the Enlightenment</em> is wrong because democracy was broadened in early 1800, till then only Kentucky and Tennessee could elect and only white men and wealthy could vote, around 1820 eight states were participating in elections and other groups as free-men could vote, later with the ratification of the U.S. Constitution and the 15th Amendment African-Americans and women were also allowed to vote.
This answer is wrong<em> Significant increase in protections for American Indians through new treaties</em>. Around this period many American Indians went to war to protect their land from the white invasions and expansion, many Indians were killed by the whites. Even there were around 368 treats between US government and American Indians from 1776-1886 most of the treaties were about land, but these treaties required the Indians to cede their lands, others to give an annuity for the territory loss, by the time Indians could not purchase American lands so the treaties did not protect the Indians.
The option <em>Rapid decline of political factions in light of an improving economy</em> is wrong because around 1829-1850 there was great grown with the Market Revolution, the improving of economy was not declined.
