Step-by-step explanation:
The question pertains to the length of time a person is expected to be disabled in order to qualify for Social Security disability benefits. According to Social Security disability criteria, in order to be eligible for benefits, workers must demonstrate that the injury or incapacity is expected to last at least twelve months. This duration threshold ensures that the benefits assist those with long-term disabilities, contributing to the aim of the Social Security program to provide economic protection to individuals who are unable to work due to a significant health-related issue.
