Which of the following is a pure risk that an insurer would generally be willing to cover?

解析

Pure risk involves only the chance of loss or no loss, with no possibility of gain, and it is the only kind of risk insurers cover. Premature death is a classic pure risk. Investing, gambling, and starting a business are all speculative risks, which carry a chance of profit as well as loss. Insurers avoid speculative risk because it is not accidental in the same way and would invite people to seek gain rather than protection against loss.
