Question

1. what was the danger of americans buying stocks on margin?

they sold more stocks.
they went into debt to buy stocks.
they bought stocks that were hot.
they avoided the risks of the market.

Explanation:

Buying stocks on margin means borrowing funds from a broker to purchase stocks. The core danger is that investors take on debt to invest, and if stock prices drop, they still owe the borrowed amount, often leading to significant financial losses. The other options are incorrect: selling more stocks is not a danger of buying on margin, buying "hot" stocks is a separate investment choice, and buying on margin increases (not avoids) market risk.

Answer:

They went into debt to buy stocks.
