Final answer:
Susan has a policy known as disability insurance, which is part of social insurance programs. These provide benefits to individuals who cannot work due to disability and have made contributions to the system when they were able to work.
Step-by-step explanation:
Susan receives income payments for a disability, where benefits are not based on her ability to perform work duties. This kind of policy is typically known as disability insurance and is a part of social insurance programs. These programs are designed to function as insurance for individuals who are unable to work due to disability, with regular payments having been made into the system by the individual or on their behalf when they were able to work.
The Supplemental Security Income (SSI) program is an example of such a social insurance program that provides supplemental income to adults or children with a disability. In contrast, another type of social insurance, retirement insurance, includes Social Security and Medicare, which are targeted at providing income and health care benefits to the elderly after regular contributions throughout their working life.
