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.

It lost interest in progressive causes.
Before and during World War I, many people who were progressive supported the war. Woodrow Wilson, who was the president of the United States at the time, made it seem like World War I was the "war of all wars" and it would end violence around the world. This seems very contradicting, but progressives believed in what he was saying along with other citizens. All of this caused progressivism to fall after World War I, as people started to realize the cruelty and death that happened during the war and associated being progressive with wanting war.

It wanted to return to a normal lifestyle.
After World War I was over, many American citizens just wanted to return to a normal lifestyle. World War I came with many casualties, hardships, and cost the United States a lot of money. Many people were tired and wanted to return back to normal and wanted to avoid another huge conflict. This caused the debate if whether or not the United States should back away from foreign affairs and even try to ignore them.

It was very concerned with the question of isolationism or internationalism.
Although some people in the United States wanted to back away from foreign affairs, isolationism and internationalism was always a question. Isolationism is the act of ignoring and not getting involved in foreign affairs and wars, even if a friendly foreign country needed help. Some people wanted this, as they didn't want anymore American casualties and debt and wanted to always remain in a normal and comfortable lifestyle. Internationalism is the exact opposite and is the act of getting involved in everything important in outside affairs and occurrences. Many people argued that this was correct, as it was important that America evolved with the country to exert and bring peace and prevent wrong doings, harmful ideologies and some countries from becoming too powerful.
Responding to xenophobic concerns, Congress passed an emergency law restricting immigration in 1921. Among other provisions, the Act established a quota (a proportional share of a total) for nationalities on the basis of their numbers in the U.S. in 1910.
The missing detail is: a quota.
