  whale is killed, the blubber is stripped off and boiled down, either board the ship or on shore. It produces a great quantity of oil which __3

  can be made into food for human consumption. A few other creatures yield oil, and none so much as the whale. The livers of the cod and __4

  which has replaced the private horse-drawing carriage. __10
