What new disaster happened when the sun came up?

• A. Mosquitos were killing him.
• B. A rescue plane appeared.
• C. It started to rain heavily.
• D. A pack of wolves attacked.

Answer: (A)

When the sun comes up, a new immediate threat from the environment appears: a swarm of mosquitoes. The scene shows morning heat drawing them in, and Brian is suddenly overwhelmed by relentless bites all over his body. This turn of events creates fresh, intense discomfort and peril that he must endure right at the start of the day, illustrating how survival in the wild can hinge on adapting to changing conditions. The option about a rescue plane would change the situation to a potential escape rather than a disaster. The rain or wolves aren’t the specific challenge described at that moment, so they don’t fit as the new disaster introduced with sunrise.
