Read the excerpt from an adaptation of "To Build a Fire."

This would delay him an hour, for he would have to
build a fire and dry out his foot-gear. At seventy-five
below zero, a man can run along the trail for half a
mile and restore his circulation if his feet are dry; but
the circulation of wet and freezing feet cannot be
restored by running when the temperature is that low.

1- The man is internally motivated by the desire to
stop and rest.

exercise.

3- The man is externally motivated by the need to dry
his feet.

outsiders.
