Read the passage from “to build a fire.” what idea is being conveyed? the dog was disappointed and yearned back toward the fire. 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. a. the dog is more fit for survival in this harsh environment than the man is. b. the dog understands why the man wants to leave the fire. c. our learning is more important than the instincts we are born with. d. the man’s ancestors were from the arctic and so were the dog’s.
