Which organization researches new and important lifesaving techniques regarding CPR?

• A. The Science Academy in Paris
• B. The Red Cross
• C. The American Heart Association
• D. McDonald's

Answer: (C)

The main idea is identifying which organization conducts research on new lifesaving CPR techniques. The American Heart Association stands out because it funds and reviews scientific research on CPR and publishes the official guidelines that shape how CPR is taught and performed worldwide. They continually update recommendations for chest compression rate and depth, minimize interruptions, and coordinate with international groups to base guidance on the latest evidence. The Red Cross provides CPR training and emergency response services, but the primary source for CPR research and guideline development is the American Heart Association. The Science Academy in Paris isn’t a recognized CPR research authority, and McDonald’s has no role in CPR research.
