Which provision is associated with the Patient Protection and Affordable Care Act?

• A. Prohibits discrimination by pre-existing conditions.
• B. Creates a universal single-payer system.
• C. Raises Medicare eligibility age to 70.
• D. Eliminates essential health benefits.

Answer: (A)

The key idea here is that the law protects people from being denied or priced out of health coverage based on their health status, especially pre-existing conditions. The provision in question prohibits insurers from denying coverage, canceling coverage, or charging higher premiums simply because someone has a pre-existing medical condition. This change made it much harder for individuals with illnesses to be left uninsured and aligned with the goal of widening access to affordable care.

This is why the correct option fits best: it directly reflects the ACA’s consumer-protection pledge not to discriminate on the basis of health status. The other descriptions describe policies that the ACA does not implement—it's not about creating a universal single-payer system, it does not raise the age for Medicare eligibility, and it does not eliminate essential health benefits (in fact, it requires coverage of essential health benefits).
