Key difference/s between the 1929 Crash and previous stockmarket crashes was/were

A) The impact of the investor's pools
B) That many middle income people were stockholders
C) All of the choices
D) The government's intervention

I think it's all of the choices, but I'm not 100% sure.

I agree with your answer.

To determine the key difference(s) between the 1929 Crash and previous stock market crashes, let's examine each option:

A) The impact of the investor's pools: Investor pools, or investment trusts, were common during the 1920s. They allowed small investors to pool their resources and invest in stocks, which influenced the market. This was not necessarily unique to the 1929 Crash, as previous stock market crashes also involved investor speculation and pools.

B) Many middle-income people were stockholders: During the 1920s, a significant number of middle-class Americans became stockholders for the first time due to the widespread promotion of stock ownership. This increased the number of people affected by the crash. This factor can be considered a distinguishing characteristic of the 1929 Crash compared to some previous crashes when stock ownership was primarily limited to wealthy individuals.

C) All of the choices: If all the options listed (A, B, and D) are correct, then this would be the answer. It suggests that the impact of investor's pools, the presence of middle-income stockholders, and government intervention were all differentiating factors.

D) The government's intervention: Following the 1929 Crash, the U.S. government initially did not take significant measures to intervene in the stock market. The lack of government action may have contributed to the severity and duration of the ensuing Great Depression. However, it is important to note that government intervention or lack thereof has been observed in various stock market crashes throughout history.

Considering the statements above, option C ("All of the choices") seems to be the most accurate answer. It reflects the significance of investor pools, the presence of middle-income stockholders, and the government's intervention as key distinguishing factors of the 1929 Crash compared to previous stock market crashes.
