Final answer:
War bonds raised money by selling bonds to the public, providing a secure investment with guaranteed repayment and interest. The revenue from these bonds helped finance the war effort and stimulated post-war economic recovery.
Step-by-step explanation:
The way war bonds raised money during wartime involved selling bonds to the public. These bonds were a form of loan that individuals could purchase to support the war effort. The revenue from these bond sales helped finance the war and provided a way for ordinary citizens to contribute financially.
War bonds were considered a secure investment because they provided guaranteed repayment with interest. The interest earned on these bonds would be used to help many families purchase more goods once the war was over and ensure that civilian production would resume.
