It had a very positive impact because the 1920's was when many new technologies were introduced, one example being the the assembly line, which made many industries more productive and profitable.
Hope that helps!
Car production increased rapidly.
Henry Ford wanted to build both sturdy and cheap cars for the multitudes, and the assembly line method of production allowed him to improve his profit margin and reduce both the time of production and the cost of the vehicle to buyers. That´s how the Ford Model T became the best-selling vehicle of all time (until 1972), was the first car to reach a million sells and, by then, it accounted for half of all the cars in the world.
1- The correct option is the third one. The "brain trust" was a group of smart advisers, who would assist Roosevelt in guiding the nation forward .
Brain trust is the name given to a group of economists, lawyers, and renowned academics, who acted as advisors to President Franklin Roosevelt since before his candidacy in 1932, and also after his promotion to the Presidency in January 1933, advising in particular the administrative policies developed during the New Deal to combat the Great Depression.
2- The correct option is the first one. Fewer regulations and lower taxes helped manufacturers keep up with consumers in the 1920s.
The lack of market regulation generated a speculative bubble that ended up exploding with the Crash of 1929, giving rise to the Great Depression.
3- No options are shown to answer this question.
4- The pattern of continually purchasing goods at ever-increasing prices is called consumerism. It is the purchase or accumulation of non-essential goods and services.
5- During the Great Depression, unemployment and new banks emerged in the United States. Unemployment in the United States increased to 25%.
6- In the 1920s, new technologies in the assembly and manufacturing made car production increase rapidly.
7- In the 1920s, businesses and industries bought stocks on margin, causing the economy to slow down.
During the years prior to the Great Depression, production and demand for products increased in the United States, with a profound productive transformation dominated by technological innovation. Optimism and economic boom also involved the Stock Exchange, which experienced a prolonged increase in prices, which allowed the formation of a speculative bubble, financed by credit. Since before the summer of 1929, several macroeconomic indicators had begun to suffer a slight decline, without the economists of the time detecting it and taking appropriate preventive measures.
