This man did not know cold. possibly all the generations of
his ancestry had been ignorant of cold, of real cold, of cold
one hundred and seven degrees below freezing-point. but
the dog knew; all its ancestry knew, and it had inherited the
knowledge. and it knew that it was not good to walk
abroad in such fearful cold. it was the time to lie snug in a
hole in the snow and wait for a curtain of cloud to be
drawn across the face of outer space whence this cold
came.
based on the evidence in this passage from "to build a fire," which statement
is the best example of the theme?
