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.
One example: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Now, solve this: Article: They once seemed more at home on the busy streets of Asia like Delhi, Calcutta and Bangkok but cycle powered rickshaws   can now be seen taking people across town in many European cities. Many people believe that rickshaws are a good way of experiencing a city close-up, while also cutting down on traffic jams and pollution. In Berlin, one of the first cities to introduce this new model of transport, more than 200 bike-taxis go along at 15km per hour, past many tourist attractions and city parks. "It is completely environmentally friendly; we have new models with an engine to help the driver up the hills but they use renewable energy." said a spokesman for VELOTAXI, the leading rickshaw company which has carried a quarter of a million people this year. While the city still has 7,000 motor-taxis, rickshaw company officials say their taxis' green ideas, speed and safety make them more than just a tourist attraction. While now increasingly out of fashion in Delhi, Berlin people have eagerly accepted the new fleet since their launch in 1997. "It's better than a taxi, better than a bus, better than the train," said ULF Lehman, 36, as he leapt out of a rickshaw near the world famous Brandenburg gate. "It feels so free." " _ ," said another traveler. In Amsterdam, driver Peter Jancso said people like to be driven around in his bright yellow rickshaw and pretend to be a queen in a golden carriage. "I like my passengers to feel important," he said as he dropped off another passenger. Another visitor noted how cheap it was compared with a normal taxi. Although increasingly popular in Europe, it is the opposite in India, where hand-pulled rickshaws are considered inhuman and a symbol of India's backward past. Nearly 500 bike-rickshaws are running in London and are not required to pay the city's road tax but things may change as other taxi drivers complain of unfair treatment. 
 Question: Where are rickshaws becoming more popular? 
 Options: (A) Delhi, Berlin, Paris. (B) Berlin, Amsterdam, London. (C) Athens, London, Berlin. (D) Amsterdam, Bangkok, Delhi. 
 Asnwer: B
