Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game. Why is poker so difficult? Chess and Go are "information complete" games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an "information incomplete" game. Players have to guess opponents' hands from their actions--tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars. Scientists believe it is only a matter of time before AI once again _ humans, hence our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural networks and reinforcement learning . Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better. Mr Heinrich told Sky News: "Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations." After two hours of quite defensive play, from the computer at least, we called it a draw. Options: A The new procedure of AI has some features of humans. B Computers are stronger than humans in every aspect. C Humans will beat computers at playing poker forever. D Scientists feel unhappy about the result of the poker game. Answer: A The new procedure of AI has some features of humans. Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: A four-wheeled robot,known as Rover,has been tested by a team at Sydney University.It was used to move a herd of cows from a field to a dairy . Researchers were amazed at how easily cows accepted the presence of the robot.They were not disturbed by it and the gathering process was calm and effective.Because the robot moved in a steady manner it allowed cows to move at their own speed,which was important in reducing injuries among cattle,said Dr Kendra Kerrisk,dairy researcher and associate professor. The robot was adapted from one that was already being used to monitor fruit and trees on farms.A team at Sydney University's Centre for Field Robotics improved the robot so that it could be put in a field with cows in order for the researchers to gather data on robot--cow interaction. The robot needs to be operated by a human but it's hoped that in the future a version can be developed that will be fully automated.As well as gathering cows a new version could also collect information useful for farmers. Using robots to get cows to the dairy will be better for their well-being."The research is in its very early stages but robotic technologies certainly have the potential to transform dairy farming,"said Dr.Kerrisk."When we have discussed this concept with farmers they have been extremely excited and we have had a series of calls and emails asking how they can get hold of one,"she added. The robot could also cut down the number of accidents involving humans on farms.Most dairy farmers in Australia use bikes to round up their cattle and they are one of the leading causes of injury.The team hopes that by using the robot to do the job instead,accident rates could fall. Options: A milk the cows on the field B feed the cows with food C round up cows on dairy farms D take farmers around the farm Answer: C round up cows on dairy farms Question:???
output answer: The robot Rover was mainly used to _ .

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Are people less happy or more happy the older they get ? A study found that people generally become happier and experience less worry after age 50. In fact, it found that by the age of 85, people are happier with their life than they were at 18. The finding came from a Gallup survey of more than 340,000 adults in the United States in 2008. At that time, the people were between the age of 18 an 85. Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of 22 and 25. Stress levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and those in their early seventies. But the people least likely to report feeling negative emotions were those in their seventies and eighties. The survey also found that men and women had similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men did. The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age. So why would happiness increase with age ? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences. The original goal of the study was to confirm the popular belief that aging is connected with increased sleep problems. The survey did find an increase during middle age, especially in women. But except for that , people reported that they felt their sleep quality improved as they got older. Options: A In their twenties. B In their fifties. C In their seventies. D In their eighties. Answer: A In their twenties. Question:
