A judge was working in his room one day when a neighbour ran in and said, "If one man's cow kills another's, is the owner of the first cow responsible?" "It depends," answered the judge. "Well," said the man, your cow has killed mine. "Oh," answered the judge. "Everyone knows that a cow cannot think like a man, so a cow is not responsible, and that means that its owner is not responsible either." "I am sorry, Judge," said the man. "I made a mistake. I meant that my cow killed yours." The judge thought for a few seconds and then said," When I think about it more carefully, this case is not as easy as I thought at first. "And then he turned to his clerk and said, "Please bring me that big black book from the shelf behind you." The neighbour asked the judge  _  .
whether the first cow was responsible whether the owner of the first cow was responsible whether both cows were responsible whether both the owners were responsible
