Problem: Given the question: Write a multi-choice question for the following article: Article: Some people may be born happy, while others are genetically negative, scientists have suggested in a study published late February in a British journal. Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter serotonin works within the brain. Serotonin, a hormone , passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant drugs regulate serotonin levels. Scientists had also identified three variants of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images, such as fierce animals, and a clear liking for positive ones, such as flowers. Researchers from the University of Essex in Britain showed participants a series of images, which were divided into three kinds: negative ones aimed at inspiring fear or stress such as a snake or person about to commit suicide, pleasant ones and neutral ones. The participants who had the long variant of the 5-HTTLPR gene "showed a clear dislike of negative material alongside a careful attention for positive material," the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction. In January, the Australian government organized "happiness workshops", teaching government staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren't productive staff. Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn't increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see.

input question: Write a multi-choice question for the following article: Article: Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia. The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn't become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around. But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modem road design. In the mid-1700s, a Frenchman came up with a new design of road--a base layer of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same lime, metal hubs (the central part of a wheel) came into being, followed by the pneumatic tyre in 1846. Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads . As wheel design took off, vehicles got faster and faster.???
output answer: Question: What might explain why transport wheels didn't become popular for some time?Options:A Few knew how to use transport wheels.B Humans carried farming tools just as well.C Animals were a good means of transport.D The existence of transport wheels was not known.Answer:C

Please answer this: Write a multi-choice question for the following article: Article: The triathlon promises to be one of the most popular Olympic sports.Recently it has drawn huge crowds attracted by athletes swimming 1,500m,cycling 40km,then running 10km without stopping.But what makes an attractive 17yearold girl give up everything for the doubtful pleasure it offers? Melanie Sears has not yet learnt those oftenrepeated phrases about personal satisfaction,mental challenge and higher targets that most athletes use when asked similar questions."You swim for 1,500m,then run out of the water and jump on your bike,still wet.Of course,then you freeze.When the 40km cycle ride is over,you have to run 10km,which is a long way when you're feeling exhausted.But it's great fun,and all worth it in the end," she says. Melanie entered her first triathlon at 14 and she won the junior section.Full of confidence,she entered the National Championships,and although she had the second fastest swim and the fastest run,she came nowhere."I was following this man and suddenly we came to the sea.We realised then that we had gone wrong.I ended up cycling 20 kilometres too far.I cried all the way through the running." But she did not give up and was determined that she never will."Sometimes I wish I could stop,because then the pain would be over,but I am afraid that if I let myself stop just once,I would be tempted to do it again."Such doggedness draws admiration from Steve Trew,the sport's director of coaching."I've just been testing her fitness," he says, "and she worked so hard on the running machine that it finally threw her off and into a wall.She had given it everything,and she just kept on." Melanie was top junior in this year's European Triathlon Championships,finishing 13th."I was almost as good as the top three in swimming and running,but much slower in cycling.That's why I'm working very hard at it." She is trying to talk her longsuffering parents,who will carry the PS1,300 cost of her trip to New Zealand for this year's world championships,into buying a PS2,000 bike,so she can try 25km and 100km races...
