Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Example Input: Article: Howard Dill is a giant among giant pumpkin growers. He grew world champion pumpkins for four years running,from 1979 to 1982, and missed winning the fifth year by only 5 pounds. Today, his Dill Atlantic Giant seeds are sold worldwide to more than 50 seed companies. The pumpkins grown from his Dill Atlantic Giant seeds commonly weigh in at over 1,000 pounds. "I don't have any training in genetics ; it was all trial and error," Dill says. He got his love of pumpkins from his father and has enjoyed growing them for years. Dill still grows giant pumpkins, but not for competition. In the fall, visitors come to enjoy the pumpkins on his 90-acre farm in Nova Scotia, Canada. He plants ten acres of pumpkins for Halloween and two acres of giant pumpkins. One of giant pumpkins was recently baked into 442 pumpkin pies and sold at $5 each for charity. It you want to try growing a giant pumpkin, Dill recommends starting with a soil test and then adding fertilizer as needed. Plant the giant pumpkin seed. A giant pumpkin can gain 15 to 20 pounds a day, so careful watering--every day or two--is necessary. You should wait about 130 days until the pumpkin matures and then you can harvest it. Dill's favorite pumpkin set the Guinness Book record in 1981. It weighted 493.5 pounds. "I've grown them larger since, but that one meant a lot," he remembers. "I never would have imagined ten years ago that there would be a 1,000-pounder, but there are many of them now," says Dill. The 2006 world record holder is Larry Checkon of Pennsylvania. He grew a 1,469 pounder. Dill says, "These world champions are grown from my seeds, so I feel like a winner right along with them."
Question: What can we learn about the world champion pumpkin of 1983?
Options: (A) It weighed over 1,000 pounds. (B) It was missing after the competition. (C) It was 5 pounds heavier than that of 1982. (D) It was 5 pounds heavier than Dill's biggest one that year.
Example Output: D

Example Input: Article: Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together. Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math. Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement. The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement. "Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math," said Beilock, professor in Psychology and author of Choke, a book about stress and performance. "These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way." Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math. The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end.
Question: Bedtime Math is an iPad app that _ .
Options: (A) requires parents and children to answer reading comprehension questions (B) assesses children's math achievement and parents' nervousness with math (C) teaches children how to count, recognize shapes and solve practical problems (D) encourages children together with their parents to solve math story problems
Example Output: D

Example Input: Article: Not very long ago, the question would have seemed absurd. Now it is on the lips of respected scientists; MPs are beginning to talk of "a war on sugar", and even England's chief medical officer has said sugar may have to be, like the old enemy tobacco, taxed in order to protect the nation's health. There came a time in the evolution of public attitudes to smoking, when the doctors had been shouting for long enough that the public was broadly aware of the risks and the only question left,for Government was: what should we do about it? Some believe we are now at the same point in our attitudes to sugar. Others - largely but not only representatives of the food and drink industry - say the entire debate has been skewed, by those who spread stories deliberately to make people nervous. More or less everyone agrees that eating too much sugar is bad for you. There is also no doubt obesity is a growing problem which is putting a significant, avoidable burden on the NHS by increasing the rates of diabetes, heart disease and other long-term conditions. But to what extent is sugar - rather than saturated fats, or salt, carbohydrates or proteins, or any of the other devils of modem diets - the cause of obesity and how much should we worry about it? Yesterday, hopes of achieving anything resembling clarity from the World Health Organisation (WHO) were confused once again, which, widely expected to reduce the recommended sugar intake by a half in new draft guidance, instead said it would continue to recommend that sugar make up no more than 10 per cent of the energy we consume, while adding that cutting this to five per cent would have "additional benefits". The decision will now go out to public consultation. Simon Capewell, professor of the University of Liverpool, said that he suspected "dirty work" on the part of food and drinks companies might lie behind the WHO's less than resounding message. "The food industry say Govemment has no business interfering in families, we must protect personal choice," Professor Capewell said. "We say there is no personal choice. At the moment, a mother can walk into a supermarket with a choice of four tomato soups - with three, or four, or five teaspoons of sugar in them. She has a choice of thousands of ready meals - with five, or six, or even nine teaspoons of sugar in."
Question: By referring to smoking the author indicates that
Options: (A) sugar has just turned out to be as harmful as smoking (B) it is not easy for authorities to restrict or ban something (C) it is easy for people to see bad effects of something (D) people must see the disadvantages of sugar immediately
Example Output:
B
