Question

Explanation:

U.S. Social Security provides disability income replacement, survivor benefits for dependents, and retirement income replacement. It does not replace the need for private health or life insurance; Medicare (a separate program) covers some health needs for retirees, but Social Security itself does not substitute for health/life insurance.

Answer:

It replaces the need for health and life insurance
