Final answer:
The term 'defensive stocks' refers to stocks that maintain stable performance even in a faltering economy, and this definition is correct. A major cause of the 1929 stock market crash was risky investments with borrowed money. The market revolution led to profound socio-economic transformations in the United States.
Step-by-step explanation:
Stocks that typically perform well during a faltering economy are indeed categorized as defensive stocks. They are called this because these stocks tend to be associated with companies providing essential services or goods, such as utilities, healthcare, or consumer staples, which remain in demand regardless of economic conditions. Therefore, the statement that stocks that perform well in a faltering economy are called defensive stocks is True.
Regarding the causes of the stock market crash of 1929, one of the pivotal factors was that investors made risky investments with borrowed money, a practice known as buying on margin. It was this excessive leverage that helped to inflate stock prices and eventually led to a spectacular crash when investors could not cover margin calls.
The market revolution in the United States brought widespread social and economic changes, such as improved transportation systems, increased industrialization, and the expansion of the marketplace for goods and services. It had significant impacts on the U.S. economy and society, confirming that the statement regarding the market revolution bringing many changes is True.
