Write a multi-choice question for the following article: Article: Fahad Azad, an engineer in India, invented a robot named DuctBot.The toy-car sized DuctBot measured 23 centimeters in length, 19 centimeters in width and 9 centimeters in height and weighs just two kilograms. The robot is designed to snake through dark, narrow air conditioning ducts and clean them.A pair of LEDs fitted on the robot light up the dirty scenery, so _ can be captured by a camera. In order to control it more easily, Mr. Azad chooses to fix DuctBot on wheels.The robot can clean off lots of dirt, as well as dead pigeons and insects.Keeping indoor air in good quality and monitoring carbon-dioxide levels in buildings with central air conditioning is a challenge.It is important in some places where clean air can mean a difference between life and death, such as hospitals.Dirty air has a bad influence on people's health. EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad's invention in a national newspaper after he had won an international robotics competition.EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work.Across India, for example, the task still falls to children.They are small enough to go through those ducts. In 2005, Mr. Azad who was still at university decided to do something about it.Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners. Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage pipes.Their biggest challenge is to make the robots user-friendly enough.Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers.There will be lots of difficulties they need to overcome in the future.
Ans: Question: What can the Ductbot do for us?Options:A Clean off the dirt in the ducts.B Control the central conditioning.C Reduce carbon-dioxide in buildings.D Protect more animals in city.Answer:A

Write a multi-choice question for the following article: Article: I have some work in Glasgow today. I was on a really tight schedule, which meant I would have no time for myself all day. I was having one of those days, the train was completely packed out and the conversation going on around me seemed to be particularly meaningless. On top of all that, I had a bit a headache. Walking quickly across the hall, I fished some change from my pocket. There was usually someone at the exit selling The Big Issue(a magazine that helps homeless folk earn a living). As the crowd parted ways at the bottom of the hall, I saw someone selling the Big Issue. You had to be homeless to sell the Big Issue. She really looked like she'd been sleeping rough. Her clothes were ragged and she was also rocking from side to side. At first I thought maybe she was trying to keep warm against the biting wind, But she wasn't ,she was moving in time to a tune. I couldn't hear her, but I could see her lips moving. As I got closer, I saw a white cane hanging from her elbow and noticed that she had sunken( ) eyes. She was blind, dirty and living on the streets. I came closer and through the noise of the traffic I heard her sing the immortal line, "--and I think to myself, what a wonderful world!" I bought her last magazine for twice what I'd originally intended. She thanked me, then she picked up her stuff and went tapping off along the pavement--still singing! So, I have my happy memory for the day. And I think it will stay with me a long ,long time. Feel free to borrow it if you like.
Ans: Question: What's the best title for the passage?Options:A A happy memory to lift you up.B An unforgettable day I experienced.C The roses in her hand, the flavor I have.D A bird in the hand is worth than two in the bush.Answer:A
