In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Input: Consider Input: Article: Petroleumis a very important mineral. It gives us heat and light. It gives us power for our cars, planes, and ships. Also, it gives us power for machines of all kinds. How is petroleum formed? Scientists believe petroleum comes from the remains of plants and animals (Remains are what is left after a plant or animal has died.) What exactly is petroleum? Petroleum is a mineral that is a mixture of hydrocarbons. It is an oily liquid, which may be brown, green, or black in colors. The word "petroleum" comes from Greek. It means "rock oil". Crude (, ) oil is petroleum that comes directly from deep in the ground. It is then taken to a refinery. a refinery is a kind of factory to refine oil. At a refinery the crude oil is separated into many parts. From the refined petroleum we get important things, such as gasoline, kerosene, fertilizer, detergents and a lot of other useful things. In fact, there are thousands of such things that we can get. Petroleum really is of great value!
Answer: " Petroleum" is a German word.

Output: Which of the following is Not true?

Input: Consider Input: Article: Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness usable wind energy produced by man-made technologies. One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity. According to Pradhan's proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts of electricity could be harvested each day. Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device called T-Box that harnesses wind energy from speeding trains. T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers , which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track. A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box's design won a silver medal in last year's Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province. Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn't taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance of the device. We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.
Answer: It is based on Pradhan's idea.

Output: What can we learn about T-Box?

Input: Consider Input: Article: Britain's symbolic red phone boxes have become out of date in the age of the mobile, but villages across the country are stepping in to save them, with creative intelligence. Whether as a place to exhibit art, poetry, or even as a tiny library, hundreds of phone boxes have been given a new life by local communities determined to preserve a typical part of British life. In Waterperry, a small village near Oxford, the 120 residents have filled the phone box next to the old house with a pot of flowers, piles of gardening and cooking magazines, and stuck poems on the walls. They took control of the phone box when telecoms operator BT said it was going to pull it down, an announcement that caused such dissatisfaction that one local woman threatened to chain herself to the box to save it. "I'd have done it, " insisted Kendall Turner. "It would have been heartbreaking for the village. " Local councilor Tricia Hallam, who came up with the idea for the phone box's change, said quite a few people would have joined her, adding, " We couldn't let it go because it's a British symbol." Only three feet by three feet wide, and standing 2.51-meter tall, the phone boxes were designed by Giles Gilbert Scott in 1936 for the 25thanniversary of the reign of King George V. Painted in "Post Office red" to match the post boxes, they were once a typical image of England and the backdrop to millions of tourist photographs. Eight years ago there were about 17,000 across Britain, but today, in a country where almost everybody has a mobile phone, 58 percent are no longer profitable and ten percent are only used once a month. "On average, maintaining them costs PS800 a year per phone box-about PS44 million annually," said John Lumb, general manager for BT Payphones.
Answer: Because the red phone boxes may be useful for some people in emergency.
Output: Why do the villagers want to keep the red phone boxes?
