I think it’s The first one!!
<span>They were veterans of World War I, had been promised a bonus for their service but the Government failed to fulfill this promise.
This led to the movement known as the Bonus MArches, where around 43,000 people marched together and occupied washington monument to demand the bonuses that promised to them.</span>
<span>Automobiles were luxury items owned by a few until the idea of interchangeable parts came along which helped with the formation of an assembly line. This made making cars faster, which means there were more of them and were easier for less rich people to get.
Hope this helps :)
