In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

[EX Q]: Article: Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time dreams and better memory in people who were learning a new skill. In the study,99 college students between the ages of 18 and 30 each spent an hour on a compute, trying to get through a virtual maze .The maze was different place each time they tired--making it even more difficult. They were also told to find a particular picture of a tree and remember where it was. For the first 90 minutes of a five-hour break, half of the participants stayed awake and an half were told to take a short nap .Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dreams before sleep and after sleep--and they were awakened within a minute of sleep to describe their dreams. Stickgold, a neuroscientist ,wanted to know what people were dreaming about when their eyes weren't moving during sleep. Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working ; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps. Stickgold suggests the dream itself doesn't help a person learn--it's the other way around.He suspects that the dream was caused by the brain processes associated with learning. All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn't take a nap, didn't show the same improvement.
Question: Before having a short nap, participants of the experiment were asked to _ .
Options: (A) stay in a different place in the maze (B) design a virtual maze which is difficult to get through (C) experience the experiment and try to remember something (D) get through a virtual maze on a computer from the same place
Asnwer: C
[EX A]: Yes

[EX Q]: Article: Engineers should embrace the arts, Sir John O'Reilly, a fellow of the Institution of Engineering and Technology, argued in a lecture. About 59% of engineering companies in the IET's 2014 survey feared skill shortages could threaten business. "There is nothing as creative as engineering," Sir John told the reporter. He says science, technology, engineering and mathematics - often known as "Stem" subjects, are vital for a modern knowledge economy. But there is a massive shortfall in the number of recruits - with a recent study by the Royal Academy of Engineering saying the UK needs to increase by as much as 50% the number of Stem graduates it produces. Delivering this year's Mountbatten Lecture at the Royal Institution, Sir John argued that engineers should recognise the role of the arts in their work - among other benefits; this could attract more people into the profession. The lecture, Full Steam Ahead for Growth, advocated a wider adoption -- Steam, or science, technology, engineering, arts and maths. Engineers should embrace the arts as being key to creativity and an important component of innovation , crucial to creating new products and boosting future competitiveness, he argued. "Engineering and technology is an increasingly diverse and creative field," said Sir John. Some university engineering departments already cooperated with art schools to develop understanding, he told the reporter. In particular he mentioned Cranfield University's Centre for Creative Competitive Design and Imperial College's work with the Royal College of Art. The two sets of people could work well together and more emphasis on the creative side of engineering could improve the success of products, he said. "Aesthetics is part of it," he told the reporter, adding that Apple's iPod was not the first digital media player, nor the only one that worked - but it came to dominate the market "because it was nice to have". Sir John said he was not suggesting universities started requiring A-level art from engineering applicants - the key subjects for admission would continue to be maths and the sciences. But an emphasis on creative skills would help "broaden the pool and attract more people in".
Question: According to a recent study by the Royal Academy _ .
Options: (A) skill shortages could threaten business (B) engineering graduates are not as creative as expected (C) there are not enough arts graduates produced in the UK. (D) the UK needs more graduates in science, technology, engineering and mathematics
Asnwer: D
[EX A]: Yes

[EX Q]: Article: There have been many great inventions, which have changed the way we live. The first great invention was one that is still very important today---the wheel. This made it easier to carry heavy things to travel long distances. For hundreds of years there were few inventions that have made as much effect as the wheel. There was little unknown land left in the world. People didn't have to explore much any more. They began to work to make life better instead. In the second half of the 19th century many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big part of our life today. The first part of the 20th century saw more great inventions. The helicopter in 1909. Sound movies in 1926. The computer in 1928, and jet planes in 1930. This was also a time when a new material was made. Nylon came out in 1935. It changed the kind of clothes people wear. The middle part of the 20th brought new ways to help people get over diseases. They worked very well. They made people healthier and let them live long lives. By the 1960s most people could expect to live to be at least 60. By this time most people had a very good life. Of course new inventions continued to be made. But man now had a wish to explore again. The world is known to man but the stars are not yet. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space.
