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.

Q: 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. 
 Question: What is the major problem of current rechargeable batteries? 
 Options: (A) They are not very stable. (B) They cannot hold enough silicon. (C) They have limited energy capacity. (D) The space between the graphene sheets is too big. 
 Asnwer: A

A: No

Q: Article: A lot of teachers hate doodlers during classes."Pay attention!"Teachers will often warn doodling students,sure that they must be daydreaming. However, according to a recent study, doodling while listening to a boring lecture helps  concentrate the attention: Andrade,a psychology professor in England asked participants to listen to a boring lecture. Half the participants were told to color in squares and circles freely on a piece of paper while listening to the lecture.The other half weren't given a task.After it was over, the participants were asked to retell the lecture. Those given the doodling task(color in squares and circles)remembered 29 percent more information than the non-doodlers.Andrade said. "If someone is doing a boring task,like listening to a dull conversation,they may start daydream,"said Professor Andrade. "Daydreaming distracts them from the task,resulting in poorer performance.A  simple task,like doodling,can stop them from daydreaming without affecting their performance at the task,"he said. So the next time you're doodling during a class,and you hear"pay attention",you can tell  the teacher with confidence that you've been paying attention to every word. 
 Question: Teachers hate doodlers because they thought  _  . 
 Options: (A) doodlers are not good at study (B) doodlers are doing no task (C) doodlers pay no attention in class (D) doodlers are not polite to them 
 Asnwer: D

A: No

Q: Article: Great Yarmouth is an English seaside town situated at the mouth of the River Yare, about 120 miles to the northeast of London. Around 5 million people visit Great Yarmouth every year, making it one of Britain's most popular seaside resorts. Formerly the home of one of the most profitable fishing industries, Great Yarmouth is a busy and very popular seaside resort. Undoubtedly, one of the most popular attractions is Great Yarmouth Pleasure Beach, a historic free entry pleasure park, which draws annually 1.5 million visitors. The two piers , Britannia Pier and Wellington Pier, both contain family-orientated entertainment. As well as the usual thrills one would expect on a classic British seafront, Great Yarmouth also has a quieter side, with a fascinating heritage quarter to explore. Not many people know that Great Yarmouth has the most complete city walls after York, with heritage walks to help you discover this medieval   attraction along with several museums and houses dating back to many centuries. If ghost walks are more your cup of tea, Eerie Tales and Yarmouth Yarns is the tour for you. Great Yarmouth is also a centre for the North Sea oil and gas industry and increasingly for offshore wind power. The Great Yarmouth Outer Harbour is a huge development currently taking place which can see larger ships coming to the town. The Great Yarmouth Maritime  Festival in September each year celebrates Great Yarmouth's maritime heritage. Over the past few years, Great Yarmouth has seen significant construction spending to improve and modernize the popular seafront area and to ensure it is linked to the town centre. Regent Road has a brilliant ceiling of light which is lit up in the evenings and is now a lovely street leading from the town centre to the seafront area. 
 Question: What can we infer about the tour of the heritage area? 
 Options: (A) It must be thrilling. (B) It is family-orientated. (C) You are advised to keep calm. (D) The visitors must love peace. 
 Asnwer: D

A:
Yes
