Which statement about aging is supported by the notes?

• A. Age is predetermined by genetics
• B. Lifestyle choices determine aging rate
• C. Aging cannot be influenced by behavior
• D. External mood affects lifespan but not aging

Answer: (B)

The main idea here is that aging is influenced by what you do, not something you can’t change. Lifestyle choices shape how quickly the body shows signs of aging by affecting cardiovascular health, metabolism, inflammation, and the risk of chronic diseases. Regular exercise, a balanced diet, adequate sleep, avoiding smoking, and effective stress management can slow the rate at which aging takes hold, even though genetics set a starting point. This is why the statement about lifestyle choices determining aging rate fits best—it recognizes that behavior can modify how fast aging processes unfold. The other ideas imply aging is fixed or entirely immune to behavior, which isn’t supported by what the notes indicate about how our actions influence aging over time.
