input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Most shoplifters agree that the January sales offer wonderful opportunities for the hard-working thief. With the shops so crowded and the staff so busy, it does not require any extraordinary talent to help you to take one or two little things and escape unnoticed. It is known, in the business, as "hoisting". But the hoisting game is not what it used to be. Even at the height of the sales, shoplifters today never know if they are being watched by one of those evil little balls that hang from the ceilings of so many department stores above the most desirable goods. As if that was not trouble enough for them, they can now be filmed at work and forced to attend a showing of their performance in court. Selfridges was the first big London store to install videotape equipment to watch its sales floors. In October last year the store won its first court case for shoplifting using an evidence a videotape clearly showing a couple stealing dresses. It was an important test case which encouraged other stores to install similar equipment. When the balls first make an appearance in shops, it was widely believed that their only function was to frighten shoplifters. Their somewhat ridiculous appearances, the curious holes and red lights going on and off, certainly make the theory believable. It did not take long, however, for serious shoplifters to start showing suitable respect. Soon after the equipment was in operation at Selfridges, store detective Brian Chadwick was sitting in the control room watching a woman secretly putting bottles of perfume into her bag. "As she turned to go," Chadwick recalled, "she suddenly looked up at the 'balls' and stopped. She could not possibly have seen that the camera was trained on her because it is completely hidden, but she must have had a feeling that I was looking at her." "For a moment she paused, but then she returned to counter and started putting everything back. When she had finished, she opened her bag towards the camera to show it was empty and hurried out of the store." Options: A guessed that the detective had seen her B was frightened by its shape C could see the camera filming D knew that the balls were for her Answer: A guessed that the detective had seen her Question:???
output answer: The woman stealing perfume _ .

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: IMAGINE if there was a device that could do everything for you - wake you up every morning, chat with you and type your e-mails. The piece of technology in question would be smart, able to tell you about the weather and where the nearest restaurants are. The good thing is you no longer need to wonder, because something like this already exists. And its name is Siri. Siri is a voice recognition application designed for Apple products and the concept has been around for almost a year. When Siri first came out it could only speak English, but now it has "learned" lots of new languages, including Chinese, Cantonese and Taiwanese, reported The Wall Street Journal. So, you can give it orders in your mother tongue. But how could a cell phone or a computer "hear" what you are saying and understand it? This is all because of voice recognition technology. When you speak, your voice creates vibrations in the air - a bit like waves in the water when you throw a rock into the lake. The microphone receives the vibrations and the computer changes them into digital data that is then divided into many parts. They are analyzed one by one to see what pronunciations each part stands for. The computer then puts these pronunciations together into possible words according to its built-in dictionary. But figuring out the words is far from enough; building words into meaningful sentences is the most difficult part. The computer has to compare what it hears to a large library of known phrases and sentences to determine what the user is saying. However, people don't always talk in the most standard way and sometimes make grammatical mistakes. This is why traditional voice recognition software always requires you to remember keywords and to speak in a certain way. Fortunately, Siri isn't like that. It's not just "voice recognition"; it's "natural language understanding (NLU)". You can ask it things like "Do I need an umbrella today?" and it will know that you are asking about the weather, according to ABC News. "The key thing is NLU -...
