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. 
 Question: Researchers did experiments on kids in order to find out _ . 
 Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness 
 Answer: B
Solution is here: Yes
Explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. Hence, B is the correct answer and output is Yes.

Now, solve this: Article: SYDNEY--Australia's economic boom is encouraging a steady stream of unexpected visitors looking for work: Americans. U.S. citizens are heading to Australia in small but growing numbers as near-10% unemployment at home drives more to look for jobs Down Under, where China's thirst for iron ore   and energy is transforming the Pacific nation into an economic powerhouse. A bricklaying student from Silver Trowel, a leading provider of quality education and training in the building and construction industry, apprentices   on a building project in Western Australia, where workers are in short supply. Daniel Davila, a 23-year-old floorer from Camarillo, California made the 14-hour move across the Pacific two years ago. He had been forced to take a job stocking shelves at a local grocery store for $8.90 an hour when he couldn't get work fixing floors. On a good day in Australia, he now makes as much as 50 Australian dollars (US$50.21) an hour--about twice the amount for a typical flooring job in the U.S. He plans to start his own flooring business.  "I can make what I did in a week in the U.S. in less than a day here," said Mr. Davila, who lives near a mining boom town in Western Australia. Australian government figures show just under 7,000 Americans currently working on long-term visas, an 80% jump over the past five years. U.S. citizens are now the third-largest group applying for so-called 457 work visas, after British and Indian nationals. Americans with degrees in areas such as accounting or mine engineering, as well as other skilled workers, can obtain a nonrenewable  permit for as much as a three-year stay. After that, they can apply for the renewable 457, which allows up to a four-year stay.  The need for workers is particularly pressing in Western Australia. The mining state's unemployment rate was 4.5% in November, below the national average of 5.2%. Drivers of heavy trucks can pull in six-figure salaries while experienced crane   operators can earn hundreds of thousands a year. Attracting skilled workers is a shift for Australia, which historically sent many of its most highly educated to the U.S. and Europe, according to migration data. 
 Question: _  , a growing number of Americans go to work in Australia. 
 Options: (A) As a result of the encouragement of Australia (B) As a result of high unemployment in the U.S. (C) Out of their ambition of finding valuable resources (D) Out of their determination to realize their dreams 
 Asnwer: A
Solution:
No
