Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: "Eat local." It's one way to reduce human effect on the planet.Eating local means to try to buy and consume foods that are grown in places close to home.However, most of the food sold at supermarkets is not locally grown or produced.Trucks and planes deliver these foods from hundreds or thousands of miles away.During the transportation, greenhouse gases are produced, causing global warming.So the shorter the distance your foods must travel, the less the harm is done to the environment. But how do you get local food if you live in a large city, hundreds of miles away from farms?Environmental health scientist Dickson Despommier and his students came up with the idea of a "vertical farm". A vertical farm is a glass-walled structure that could be built as tall as a skyscraper.Since the garden is built upwards, rather than outwards, it requires much less space than an ordinary farm.The world is quickly running out of room for ordinary farming.Vertical farms could be a key to this situation.Despommier imagines a 30-story building with a greenhouse on every floor.The walls of the building would be clear, to allow crops to get as much sunlight as possible.Depending on a city's water resources, Despommier thinks hydroponic farming is another method for the vertical farm which needs no soil to grow plants. Despommier says the hydroponic greenhouses would use a system that would use a city's waste water and fill it with nutrition to make the crops grow.If this method works, it would provide food to a city and save millions of tons of water. The idea of a vertical farm has attracted the attention of government officials around the world.Scott Stringer, a government official from New York City, thinks the city is suitable for the vertical farming."Obviously we don't have much land left for us," Stringer said, "But the sky is the limit in Manhattan." Despommier admits that there is still a lot of work to do to make vertical farms a reality."But I think vertical farming is an idea that can work in a big way." he says. Options: A It produces healthier food. B It does less harm to the cities. C It consumes more energy of the city. D It requires less transport costs. Answer: D It requires less transport costs.

The answer is:
Which is one of the vertical farm's benefits when compared with ordinary farming?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Smart home applications can share all kinds of helpful information with homeowners. There appears a new housing platform which can detect the stress on electricity -- and the stress on the heart. "There is a growing population of elderly people, and there are statistics to show that more and more of them are going to live alone in the home," said Johann Siau, a senior lecturer at the University of Hertfordshire in the U.K., who was leading the InterHome project. The system was originally designed to provide remote access to a house so owners could be more energy-efficient. In a small type of the system, set-in controller devices connect securely to the Internet. The owner can then monitor them with a cell phone or computer. User feedback helps the system adapt to routines, saving on electricity. While thinking about responding to user behavior and an increasingly elderly population, the researchers decided to add wristband technology that senses important organs of the body such as body temperature and pulse, Siau said. "If someone were to fall, it would detect the fall and it would immediately start the monitor of the pulse to see if the person has gone into shock ," he said. The wristband communicates with the home system wirelessly. Data from the band can be securely transmitted to the home network and accessed by authorized users. "We're working on trying to reduce it to a level where it could potentially be a wrist-sized product," Siau said. But he warned that the technology presented new challenges. "When you start using that on a larger scale, you have issues of privacy or security," he said. Siau said the InterHome home system isn't intended to invade privacy. "We're thinking about the elderly people who are living alone with no one looking after them," he said. "Hopefully this will be able to decrease some concerns and possibly save a few lives." Options: A sense important organs of a person B keep an old man from falling C get the medical information of a sick person D record a person's daily activities Answer: A sense important organs of a person Question:???
output answer: The wristband technology is used in the system to _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a highprotein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet. Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it's possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans. It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds----and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. "The studies are generally far too short to tell effect," Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, "It makes no real difference which of the weight-loss ways one chooses." Options: A fat B carbohydrates C protein D calories Answer: C protein Question:
----
Answer: According to Wycherley's analysis, dieters should take in more _ .

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Scores on a national test released on November 1 show that students in the U.S.A. have improved in math over the last two years, but mostly stayed the same in reading. This year, 422,000 fourth graders and 343,000 eighth graders took the exams between January and March. Students were asked to read grade-appropriate materials and answer questions for the reading test. For the math test, students answered questions about geometry, algebra, number properties, measurement and other topics. The U.S Department of Education released the scores in a report called The Nation's Report Card (NAEP). This year, students earned the highest scores ever recorded on the math exam, which has been given since 1990.Fourth graders scored an average of 241.That is a one-point increase from 2009and a 28-point increase from 1990. Eighth graders made similar progress. Then average score this year was 284,up one point from 2009 and 21 points from 1990. In reading, fourth graders scored an average of 221 points, the same average score since 2007.That score is four points above those from 1992, when the first reading test was given. Eighth graders scored an average of 265 points, up one point from 2009 and five points from 1992. Education experts say reading is a harder subject to improve in the classroom than math. While math is largely learned in classrooms, reading results depend on how much kids read outside of school and how much they read in other subjects, such as history and science. On the NAEP, math scores were the highest among students who have limited use of calculators during math lessons, compared with students who have unlimited use or no use. Reading scores were the highest among students who said they read for fun on their own time almost every day. Options: A 238 B 240 C 213 D 220 Answer: C 213 Question:

Answer:
In 1990, the fourth graders' average score on the math exam was about _
