Explanation:

In Jack London's To Build a Fire, the experienced old-timer from Sulphur Creek warns the inexperienced man about the extreme dangers of the Yukon winter. His key advice is that traveling alone when the temperature drops below fifty degrees below zero is reckless and dangerous, as the harsh conditions leave no room for error without a companion to help. The other options are either actions the man takes on his own or not the core warning from the old-timer.
