[Q]: Write a multi-choice question for the following article: Article: People should be warned against using mobile phones outdoors in stormy weather because they may"be struck by lightning",according to doctors. Three experts have described how a teenage girl was struck by lightning while using her phone in a large London park.The girl,aged 15,recovered,but a year later was still wheelchair-bound and found to be suffering complex physical and emotional problems. The girl also had a perforate eardrum on the side where she had been holding the mobile phone.She was having general recovery in Northwick Park Hospital,Middlesex. Swinda Esprit,a senior house officer, said that while the brain and muscle damage was similar to that of many lightning victims--who can experience heart attacks on being struck--the ear problems were not. She said that the damages were particularly relevant for people who might be involved in less serious lightning incidents,who might otherwise recover, but would never get their full hearing back if struck while on the phone. "We were shocked by the damage,which is why we wanted to draw attention to it,"Dr Esprit said."A year on and she still was suffering these difficult hearing." They added that three other cases had been reported in newspapers in China,South Korea,and Malaysia.In the Malaysian case,a sales executive was killed by lightning while talking on his phone during a thunderstorm near Kuala Lumpur. "All these events resulted in death,"the doctors wrote."This rare phenomenon is a public health issue,and education is necessary to stress the risk." The Australian Lightning Protection Standard recommends that metallic objects,including cordless or mobile phones,should not be carried outdoors during thunderstorms.However, "the United States National Weather Service says on its website that both are safe to use "because there is no direct path between you and the lightening". Paul Taylor, of "the Met Office'',said the ear injuries were a consequence of mobile phones being metal,and not related to radio waves. Mr. Taylor said that mobile phones should be...

input: Please answer the following: Write a multi-choice question for the following article: Article: Alex stared through the cabin window at the darkness. Soon his dad would call him. And he didn't want to go. He wished he hadn't come to the lake for the weekend. "We're ready," Dad said as he came in from the porch. " Grab your rod." Alex turned away from the window and slowly picked up his fishing rod. "Have fun!" Mom said. "Sure," said Alex, trying to make his voice bright. "We should have done this before." Dad said. "Let's catch a big one!" Dad picked up his tackle box, rod, and bait can from the porch. He clicked on the flashlight. They walked down the hill toward the lake in the narrow beam of light. The only thing Alex could see was the circle of weeds and rocks at their feet, lit by the flashlight. Insect voices filled his ears---clicks, hums, buzzes, whines. Hundreds of bugs waited in the darkness to attack. "Ow!" he blurted as he felt a sting on his arm. "Mosquitoes," Dad said. "I have brought some spray to keep them off." When they reached the boat, Alex stumbled as he climbed over the side. "I don't like this much," he said. "It's so dark." Dad squeezed his shoulder. "Don't worry. It's not as dark as you think. After a while your eyes will get used to the night." Suddenly something rushed past Alex's head. He gasped. "What was that?" "Probably a bat," Dad said. How could Dad act as if it were nothing! "Will bats be flying around our heads the whole time?" "This is their time to be out catching insects," Dad explained. "They won't hurt you. They're too busy grabbing dinner." He pushed the boat off the gravel and jumped in. Alex gazed back at the cabin. A square of light from the window glowed in the darkness. Dad rowed to the middle of the lake and stopped. "We'll just let the boat drift. Keep the flashlight in the bottom of the boat. The fish won't bite if they see light flashing around. When we've done baiting our hooks , we'll turn the light off." Leaning down to get closer to the light, Alex tried to thread a worm on his hook, but he couldn't seem to work his fingers right. So...

Problem: Write a multi-choice question for the following article: Article: What will power your house in the future? Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves -- but artificial ones. Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis . Now researchers have found a way to imitate this seemingly simple process. The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts . Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell, which uses those two materials to produce electricity, located either on top of a house or beside the house. Though the leaf is only about the shape of a poker card, scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. "One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology," said Nocera at a conference of the American Chemical Society. The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf, by contrast, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf prototype could operate continuously for at least 45 hours without a drop in activity. The wonderful improvements come from Nocera's recent discovery of several powerful, new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available; that is, it doesn't need pure water. This is important for some countries that don't have access to pure water. With the goal to "make...

A:
Question: The purpose of the scientists at MIT in developing the new artificial leaf is to _ .Options:A offer people in developing countries access to pure waterB provide cheaper energy for developing countriesC gain a deeper understanding of the photosynthesis processD build up more power stations in the worldAnswer:B
