Answer:
c. Sitting in the cockpit of a commercial airplane.
Explanation:
The National Geographic magazine article "Barrington Irving, Pilot and Educator" narrates how Barrington Irving became a pilot. Irving would become the first and youngest African American to be a pilot and fly solo around the world.
Irving had never thought of becoming a pilot at first. As he admitted, <em>"I didn’t think I was smart enough"</em>, Irving never thought about his future in the aviation scene. He was just helping out his parents at their bookstore. It was there that a chance encounter, a chance question by <em>"a Jamaican-born professional pilot"</em> and the chance to sit at the cockpit of a commercial airplane that <em>"hooked"</em> Irving to flying.
Thus, the correct answer is option c.
The subject here is simple" it's just "Antarctica" .
The verb is also not compound, it's a simple verb: "has".
The compound part of the sentence is the object: it is: "a thick ice cover and the highest average elevation of all the continents"
so the correct answer is "compound subject"
