nyad was ______.

• determined
• humble
• imaginative
• mischievous

Explanation:

To determine the correct adjective for Nyad, we analyze her actions: she set an athletic goal in her twenties and made a fifth attempt in her sixties to swim from Cuba to Florida (a treacherous route with previous setbacks like jellyfish stings and breathing issues). "Determined" means having firm resolve to achieve a goal, which matches her persistent attempts. "Humble" (modest) doesn't relate to her perseverance. "Imaginative" (creative) is irrelevant. "Mischievous" (playfully naughty) doesn't fit. So the best choice is "determined".

Answer:

A. determined
