#Question id: 24185

In Moby Dick, Herman Melville wrote that the whale men were “enveloped in whale lines,” that each man relied on the others during moments of danger.

#General Aptitude
  1. The small boats that pursued the whales left the whaling ship far behind; each man in a boat had to depend on the others to stay alive.
  2. Once the whale was harpooned, the whale line unraveled so fast that water had to be poured on it to keep it from smoking.
  3. The whale line was the rope, dozens of yards long, that attached to the harpoon; it was raveled under the seats of all the men metaphorically connecting each man to the next.
  4. One wrong move and the line would snap a man right out of the boat; thus, his life depended on whether the crew would cut the whale loose to save him, or leave him in the ocean during the heat of the hunt.
