Problem: Given the question: Write a multi-choice question for the following article: Article: If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language? According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles. The study also found the effect is greater the younger people learn a second language. A team led by Dr Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early _ " who had learnt a second language before the age of five, as well as a number of later learners. Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference. " _ "said the scientists. It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and math skills. "Having two languages gives you two windows on the world and makes the brain more flexible ," he said. "You are actually going beyond language and have a better understanding of different ideas." The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and 34. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. "Studying a language means you get an entrance to another world," explained the scientists.

input question: Write a multi-choice question for the following article: Article: Thirteen vehicles lined up last March to race across the Mojave Desert , seeking a million in prize money . To win , they had to finish the 142-mile race in less than 10 hours . Teams and watchers knew there might be no winner at all , because these vehicles were missinge a key part drivers . DARPA , the Defense Advanced Research Projects Agency , organized the race as part of a push to develop robotic vehicles for future battlefields . But the Grand Challenge , as it was called , just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance . One had its brake lock up in the starting area . Another began by throwing itself onto a wall . Another got tied up by bushes near the road after 1.9 miles . One turned upside down . One took off in entirely the wrong direction and had to be disabled by remote control . One went a little more than a mile and rushed into a fence ; another managed to go for six miles but stuck on a rock . The "winner," if there was any , reached 7.8 miles before it ran into a long , narrow hole , and the front wheels caught on fire . "You get a lot of respect for natural abilities of the living things," says Reinhold Behringer , who helped design two of the car-size vehicles for a company called Sci-Autonics . "Even ants can do all these tasks effortlessly . It's very hard for us to put these abilities into our machines ." The robotic vehicles , though with necessary modern equipment such as advanced computers and GPS guidance , had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately , Sure , that very young child, who has just only learned to walk , may not think to wipe apple juice off her face , but she already knows that when there's a cookie in the kitchen she has to climb up the table , and that when she gets to the cookie it will taste good . She is more advanced , even months old , than any machine humans have designed .???
output answer: Question: In the race , the greatest distance one robotic vehicle covered was_.Options:A about eight milesB six milesC almost two milesD about one mileAnswer:A

Please answer this: Write a multi-choice question for the following article: Article: I was 230 pounds this spring and I decided to get down to a healthier 200.In a house full of food,including snacks bought for my 7yearold sons,I had a hard time cutting calories. Then I noticed my neighbors were having diet meals .I decided to do the same,knowing I would never be able to stick to a diet if I had to do the buying and cooking myself. I was looking for food that I could afford but I might take a diet more seriously if it hurt me in the wallet. After online searches,I decided to compare the offerings of four companies:Zone Manhattan,Chefs Diet,NuKitchen and eDiets. All four would send the meals to my door. Three send food daily,while eDiets sends a large package once a week. There were dozens of companies I could have chosen.Research suggests that the economic crisis has made diet programs less _ .Consumers prefer doityourself diets with foods bought from the supermarket. NuKitchen regards itself as the "personal chef".I ordered the fiveday plan ($230.53) and the taste was disappointing. I neither lost nor gained weight on the food. eDiets promises "healthy,delicious meals sent to your door".I ordered five breakfasts,five lunches and five dinners. My total cost was $119.70,or less than $25 a day. Overall,the food from eDiets was better than that from NuKitchen. Chefs Diet charged $380.99 for seven days,making it the most expensive of the four services.I never tasted anything terrible,but I never tasted anything that made me want to renew for a second week. Zone Manhattan charged $349.80,with tax,for a week's supply of food,or about $50 a day.I liked the food so much that I lost six pounds in the first four days on the diet.
