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.
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.

Problem: Article: Many kids don't drink enough water daily, according to a new study. The study's lead author, Erica Kenney, at first planned to look into the amount of sugary drinks kids were drinking in schools. However, during her research she found that many kids were simply not drinking enough water. Kenney and her team examined data from a group of 4,000 children, aged 6 to19, between the years of 2009 and 2012. The data was taken from the National Health and Nutrition Survey,a study on the health of children in the United States conducted each year by the Center for Disease Control and Prevention.. While looking through the survey results, she noticed that more than half of the kids who took part in the study were dehydrated  . Of' that group, boys were 76% more likely than girls not to have enough water in their system. Nearly one quarter of the kids in the survey reported drinking no plain water at all. "These findings highlight  a possible health issue that wasn't given a lot of attention in the past," Kenney said in a statement. "Even though for most of these kids this is not an immediate and great health threat, this is an issue that could really be reducing quality of life and well-being for many children and youth." The United States-National Agriculture Library says average kids need between 10 to 14 cups of water every day. This water can come from a mix of drinks and foods that contain high amounts of water, such as celery, melons or tomatoes. It is also recommended that fluids come from water instead of sugary drinks that are high in calories and can lead to weight problems. 
 Question: What was Erica Kenney's purpose in doing the study? 
 Options: (A) To study if kids drink enough water daily : (B) To prove that sugary drinks are harmful to kids (C) To show what kind of sugary drinks kids love. (D) To find out how many sugary drinks kids drink at school. 
 Asnwer: D

Solution: Yes
