Read the excerpt from “Husky-The Wolf Dog of the North.” In the summer-time, when the snow and ice are gone and man travels by canoe and poling-boat, the huskies are thrown upon their own resources. They do not work; wherefore should they be fed? Hence they become splendid scavengers and perform prodigies of benevolence in the matter of sanitation. Nothing escapes them. Not a bone but is cracked for its marrow; not a tin can but shines clean and bright on the inside.

Which is the best summary of the excerpt?

During the summer, men do not use huskies to pull dog sleds because the snow has melted and they can travel by water.
Huskies are resourceful and able to take care of themselves during the summer when men do not use them to pull dog sleds.
I think huskies are probably the best scavengers in the animal kingdom, and they are also the most responsible for leaving little mess behind.
Huskies are splendid scavengers and perform prodigies of benevolence in the matter of sanitation.
