Which statement about Grandpa's health claim in Coconut Grove is true?

• A. He is the healthiest 73-year-old in Coconut Grove.
• B. He is the healthiest 70-year-old in Coconut Grove.
• C. He is not healthy at all.
• D. He is the oldest 90-year-old.

Answer: (A)

The main idea tested here is understanding a precise, age-based health claim within a specific place. The true statement is that Grandpa is the healthiest person who is 73 years old in Coconut Grove. This phrasing combines three details the text likely emphasizes: his age (73), his relative health status (the healthiest), and the location (Coconut Grove). The other options introduce different ages or imply health or status that aren’t supported by what Grandpa claims in the scene, so they don’t fit the described claim.
