The reading passage is two anecdotes written by an old man called Clancy. They are about the days when Clancy was a whaler and hunted whales on the southeastern coast of Australia at the beginning of the 20th century. It was a time when the killer whales, or “killers” as they were then called, helped the whalers catch the baleen whales that were on their annual migration.
