Questions 21-25 are based on the following passage:
In the Arctic Circle, it is not that Eskimos lack ability or industry, but the surroundings restrict constructive effort to the barest necessities of existence．This retards progress to higher develpment．
Agriculture is impossible all along the thousands of miles of the north shore．The only wood is such as drifts in．other than this driftwood, the only available building materials are snow, ice, stone, and bones of animals．All of these have been used for habitations and storage, places, differing in various tribes according to the requirements and skill of the workers．The lack of necessary timbers to build walls and span wide spaces is probably one reason why they construct their houses at least partly beneath the surface of the ground．This device also makers the houses more impervious (不能渗透的) to the cold．
Most of us are inclined to think that the Eskimo lives always in an igloo or snow house．This is not entirely true．After the long cold winter, the family is very likely to move, when the weather permits, into a tent sealskin．The actual construction of such a tent is similar to that used by other, more southerly tribes and will be described later．
The snow house, however, is an interesting and unique habitation．Our summer campers will not build, with snow, but the delicate art is worth recording and some of our winter camps mountains might try to make snow houses．
