Which disease is commonly known as the flu?

• A. Hypercapnia
• B. Mesothelioma
• C. Olfaction
• D. Influenza

Answer: (D)

The main idea here is recognizing common language for diseases. The flu is the everyday name for influenza, a contagious viral infection of the respiratory tract. People with influenza typically have fever, chills, body aches, cough, sore throat, and fatigue. The other options refer to different things: hypercapnia is high carbon dioxide in the blood, mesothelioma is a type of cancer linked to asbestos, and olfaction is the sense of smell. So influenza is the correct, widely used term for the illness known as the flu.
