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 Input: Article: Does it drive you crazy that your cell phone needs to be frequently charged for hours? A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode made of many carbon-based graphene sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available within five years, the researchers said.

Example Input: Article: JANUARY 15, 2014 KYOTO -- A father froze to death while sheltering his eight years old daughter from severe weekend snowstorms that swept northern Japan. Fujita Makoto, one of at least nine people killed as snowstorms swept across Hokkaido , died as he tried to protect his only child Yumi against winds of up to 113 kilometers per hour in Hokkaido, as temperatures fell sharply to minus 6 degrees centigrade. Makoto's body was uncovered by rescuers looking for the pair after s raised the alarm. Yumi was wearing her father's jacket and was wrapped in his arms. The pair had last been heard from at 4 p. m. on Saturday, after fisherman Makoto picked his daughter up from a school where she was being looked after while he was at work. Makoto called his s to say his truck had become stuck in the driving snow, which was several meters deep in places. He told them he and Yumi would walk the remaining kilometers. The two were found just 300 meters from the truck at 7 a.m. on Sunday. Makoto had his body bent over his daughter, gently holding her in his arms and apparently using his body and a warehouse wall to provide shelter. The small girl was taken to hospital, where she was found to have no serious injuries. Her father was officially pronounced dead by doctors at the same hospital. The newspaper Yomiuri said Yumi's mother had died of illness two years earlier. The paper quoted neighbors as saying Makoto had been an extremely caring father who would often delay the start of his working day to enjoy breakfast with his daughter. His death came as families all over Japan celebrated Girls' Day, a festival in which they gather at home and decorate houses with dolls. "He reserved a cake for his only daughter and was looking forward to celebrating Dolls' Festival together," a neighbor told the Yomiuri.

Asnwer: B
Example Output: Yes

Example Input: Article: Depressed people can be very difficult to be around,and yet they need more than the usual amount of support and understanding from their friends and family. The anger and lack of concern that a depressed person may have for people close to him or her can be very disturbing to someone who's trying to help.At such times,the sincerity of a friend or a family member is questioned when the depressed person doesn't feel worthy of someone's friendship.Withdrawal from others can make it nearly impossible to encourage a depressed person to enter into activities that may help pull him or her out of the depression. It is frequently difficult for a depressed person to carry on a conversation.Attempts to help may be met with defensiveness and verbal attacks.While being supportive and understanding,the friend of a family member must be careful not to do too many things for the depressed person.There is a very thin line between being supportive and being overly protective.Too much"doing for" can be a disservice . You can best help a friend or relative who is depressed by considering the following points: *Do not moralize.Don't pressure him or her to "put on a happy face," or to "snap out of it." Often the person will feel even worse after hearing such words. *When you are alone with your depressed friend,you might say something like,"I've noticed lately that you seem down.I care about you and would like to listen to what you're thinking about." Then be a good listener. *Don't say,"I know exactly how you feel." You probably don't.But if you've had similar experiences,sharing those may help.Say things like,"This happened to me.It might help you." Or "I know some of what you must be feeling." *Urge him or her to get professional help if necessary.Offer to accompany your friend on the first visit if it will be easier for the person.
