In this excerpt, why does Arnot say “my mind isn’t completely recovered”?
A She has just finished a grueling exercise routine.
B She has just planned a difficult route for a future climb.
C She has just spent a long time in the thin mountain air.
D She has just written a report on her latest expedition.
The correct answer is C. She has just spent a long time in the thin mountain air.
Explanation: In high-altitude environments, the reduced oxygen levels can lead to mental fatigue and a lack of clarity, which aligns with Arnot’s statement about her mind not being completely recovered. This often happens after prolonged exposure to thin air during activities like climbing or hiking at high altitudes.
