Choose two lines or groups of lines that support the inference. A) Leather harness was on the dogs, and leather traces attached them to a sled which dragged along behind. B) The sled was without runners. It was made of stout birch-bark, and its full surface rested on the snow. C) But there was life, abroad in the land and defiant. Down the frozen waterway toiled a string of wolfish dogs. D) It was the masterful and incommunicable wisdom of eternity laughing at the futility of life and the effort of life. E) There were other things on the sled—blankets, an axe, and a coffee-pot and frying-pan; but prominent, occupying most of the space, was the long and narrow oblong box.
