Business of Healthcare and Health Policy Practice Test

The provision being tested is how the ACA expanded access to private health insurance by creating organized marketplaces where individuals can compare plans and enroll, with subsidies to make coverage more affordable. These marketplaces bring together private plans under standardized rules and provide protections like subsidies for eligible people, making it easier to obtain coverage and understand benefits.

This is the best answer because it directly reflects a major feature of the ACA design: establishing health insurance exchanges (marketplaces) to facilitate private coverage with financial assistance, rather than modifying Medicare age, eliminating Medicaid expansion, or removing preventive services. The other statements don’t align with the law’s actual provisions—Medicare eligibility age was not raised to 85; Medicaid expansion was authorized (and implemented in many states) rather than eliminated; and preventive services coverage was expanded to reduce cost-sharing, not eliminated.
