Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: "Track!" said my master.

I served with the police years ago. We would never have thought of using a tracker-dog to find a car thief. Impossible. Everyone knows that dogs are useless in such matters. In a sense he was right. I'm sure there's no need to tell you that, just as a dog's hearing is much better than a human being's, so his sense of smell tells one thing from another far better than a great detective.
