Almost all Americans over age 65 are eligible for Medicare.

Option A is incorrect as Medicare does not pay for all medical bills. Option C is incorrect as Medicaid, not Medicare, provides free healthcare for poor children. Option D is incorrect as not all persons with incomes below the poverty line are eligible for Medicaid. Option E is incorrect as Medicaid is a government-run program, not run by Blue Cross.
