Final answer:
Group life insurance covers many individuals under a single contract, providing each person with proof of coverage through a certificate of insurance.
Step-by-step explanation:
Group life insures a group of people under a single contract. This type of insurance is common among employers who offer it to their employees. By having one policy cover many individuals, this simplifies the administration and often results in lower premiums compared to individual life insurance policies. Certificates of insurance are then provided to each insured individual as proof of coverage under this master policy.
