How long was Brian alone on the lake?

• A. Forty days.
• B. Sixty days.
• C. Fifty-four days.
• D. Thirty days.

Answer: (C)

Time on the lake is shown through a steady progression of events that anchor how long Brian has been isolated. The story gives a precise total: he is alone for fifty-four days before rescue. That duration isn’t just a rough guess; it’s tied to the sequence of survival milestones he achieves—building shelter, learning to make fire, catching food, and enduring the changing weather—leading up to the moment a passing plane finally spots his smoke signal and rescues him. So the best answer is the exact span the text provides: fifty-four days, about two months. The other options don’t fit the timeline the author lays out.
