Write a multi-choice question for the following article: Article: "Track!" said my master. Like any good tracker-dog who has received the command he most loves, I gave a bark of excitement, put my nose down to the ground and sniffed. The ground was rich with smells. Even in the high-class housing area where we were working, the stones held traces of many sole and confusing scents (smells). As I searched for the scent that would give me a clue to the tail of the guilty man, my tail wagged slowly, thoughtfully, delightedly. Work was like play to me; I enjoyed it. A small group of people gathered behind us. Among these onlookers was the old caretaker of the building next door to ours. He spoke in a scornful voice, "You actually think your dog might catch a thief three days after the event?" My master said nothing, but I'm sure he must have smiled. I did not turn to look. I knew he would not speak unless it was to give me a new command. I needed to concentrate. My task was difficult. I had to pick out one scent among the many that lay about and then tracked it to its source. "You're wasting your time," said the caretaker. I looked at him without raising my head. He was running his hand over his fat stomach. His rough palm and smooth shirt combined to make a slight noise. It was part of my training to be aware--often it is only a little whisper of a noise that alerts you to be drawing of a weapon. But of course the aging caretaker was going to do no such thing. There was no smell of fear or nervousness about him. He was merely being clever and talkative. "I've seen many tracker-dogs in my time," said the caretaker to the onlookers. 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.

Write a multi-choice question for the following article: Article: The English language is different from any other language. Yet English words do not stay the same. The language is always changing. We need new words for new inventions and new ideas. Different words come into use, or older words are used in a new way. English can change by borrowing words from other languages. Tomato was borrowed from Mexico and pajamas from Indian. The word coffee came from Turkey, and tea came from China. Now new space and science words are being borrowed from other countries, too. New words are also made by adding two words together. Strawberry, popcorn, and grandfather are words made up of two parts. Sometimes new words are shorter forms of older words. The word photo was made from photograph by cutting off the end of the longer word. Plane was made by cutting off the front part of airplane. Smog was made by using only the first two and last two letters from the words smoke and fog. The names of people and products can become new words. Our sandwich was named after a man named Sandwich. Scotch Tape, Band-aid and Jello were names made up by the companies that first made the products. ,.
