Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Millions of sports lovers are still thinking about one thing----the Winter Olympics in Sochi Russia. Close to 2900 men and women competed in the 2014 Winter Games about a month ago. The Olympics brought a lot of attention to Sochi, a city on the Black Sea, which is a popular area for vacation travelers. The area is known for its mild winters. At least $50 billion was spent on the 2014 Winter Games, making it the costliest Olympics in history. Seven billion dollars was spent on the 2010 Winter Games in Vancouver, Canada. Olympic officials chose Sochi to host the 2014 games almost seven years ago. At that time, Russian President Vladimir Putin said the games would cost about $13 billion. Yet the actual expenses exceeded his estimate. So where did all the money go? Some observers say the high cost is partly the result of security measures. Brian Jenkins, a terrorism expert from the RAND Corporation, gave the following explanation. There were anywhere between 70,000 and 100, 000 policemen and military troops deployed around the city. The main threat came from separatist and Islamist groups from the North Caucasus, especially from Chechnya and Dagestan. One group claimed responsibility for two suicide bombings in Volgograd last December. The attacks killed more than 30 people. The city is only about 600 kilometers away from Sochi. Bruce Hoffman is a terrorism expert from Georgetown University in Washington DC. He says the increased security made Sochi a difficult target for terrorists. It is thought that the terrorists' intention was to make life difficult for the Russians and to create some sort of incident that would take away the enjoyment. The last Olympians from around the world on Russian soil were in 1980. That was a year after Soviet troops invaded Afghanistan. More than sixty countries didn't take part in the Moscow Summer Games to show their anger.

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Many of us are used to hearing stories of people being pickpocketed in busy places. But most of us are aware of the dangers, so we are safe - at least, we think we are. According to a BBC report, a growing number of thieves are trying to "hack our mind's weaknesses" to get their hands on our possessions. "In fact, the key requirement for a successful pickpocket isn't having quick fingers," said the report. By using psychology, some pickpockets are taking advantage of the loopholes in our brains. Our lack of ability to multitask is one of the most important loopholes used by pickpockets, the report explains. While this can often be a good trait , allowing us to focus on the most important details in our surroundings, "a good trickster can use it against you, " said neuroscientist Auzana Martinez-Conde. "It's all about directing people's attention toward something else," said James Brown, who studies the tricks of pickpocketing. Confidence, the power of suggestion, and certain hand movements such as moving your hands in an arc are all said to be things that fool us. Groups of pickpockets use a common trick designed to create a scene and confuse victims. The first gang member, a "blocker", walks in front of the victim and suddenly bumps into them. A second member of the gang then bumps into both of them from behind and stages an argument with the "blocker". In the confusion, both men steal what they can and pass it to a third thief who quickly runs off with the stolen goods. Some thieves go even further to exploit our psychology by hanging out near signs reading "beware of pickpockets". Since this is one of the last places people expect to be robbed, many check where their valuables are, giving away their location to thieves. But according to Brown, as long as we don't daydream in public, we shouldn't be worried. "A street thief will avoid like the plague " people who are demonstrating a very open awareness of their environment," he said. Options: A They think it is more thrilling to steal in those areas. B Normally there are no police officers around. C They don't know common people's psychology. D They have a better chance of locating people's valuables there. Answer: D They have a better chance of locating people's valuables there. Question:???
output answer: Why do some thieves hang out near signs saying things like "beware of pickpocketers"?

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Trees should only be pruned when there is a good and clear reason for doing so and , he number of such reasons is small . Pruning involves the cutting away of overgrown and unwanted branches , and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way . First , pruning may be done to make sure that trees have desired shape or size . The object may be to get a tree of the right height , and at the same time to help the growth of small side branches , which will thicken its appearance or give it a special shape . Secondly , pruning may be done to make the tree healthier . You may cut out diseased or dead wood , or branches that are rubbing against each other and thus cause wounds . The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air . One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal . Often there is a race between the healing and the disease as to whether the tree will live or die , so that there is a period when the tree is at risk . It should be the aim of every gardener to reduce that risk of death as far as possible . It is important to make the area , which has been pruned , smooth and clean , for healing will be slowed down by roughness . You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose . Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference from the leaves and also it is very unlikely that the cuts you make will bleed . If this does happen , it is , of course , impossible to paint them properly . Options: A To make the tree grow taller . B To improve the shape of the tree . C to get rid of the small ranches . D To make the small branches thicker . Answer: B To improve the shape of the tree . Question:
