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: Experts believe that storms and severe weather in North America and Asia have disrupted bird flight paths across the world and swept huge numbers of bird species towards the British Isles. Birds flying to the other side of the Atlantic or to the Pacific to lay their eggs have been trapped in Britain and Ireland, adding their numbers to native species, and causing great excitement in the bird-watching community. Local birdwatchers have already observed a total of 442 species in the British Isles this year. The highest number ever seen in one year is 445, in 2008. "We only need four more to break our record," said Lee Evans, who runs the British Birding Association. "With three months to go I'm sure we'll do it." Last month an extremely rare Siberian Rubythroat bird was seen in Scotland, sending hundreds of birdwatchers north in the hope of catching a glimpse of this colourful Asian beauty. Another very uncommon bird, the bufflehead duck was cited in Cornwell and caused similar excitement. "I couldn't believe it," said Evans. "The poor thing was completely _ . It must have been blown to England by the storms while trying to fly from Canada to the southern United States for the winter. That's 3000 miles!" Evans said that global warming over the past decade was playing a key role in transforming bird movements across the world. In addition, melting Arctic sea ice may also be opening up bird flight paths over the North Pole, making it easier for birds from the Pacific -- such as the slaty-backed gull and tufted puffin, both of which appeared in London earlier this year -- to reach Britain. Bird-watching is becoming an increasingly popular hobby among all age groups, added Evans. "A fifth of our members are under 18. This is a round-the-year hobby that you can enjoy from the kitchen window or from a car. More and more people are bird-watching, and as a result more and more unexpected species are being spotted in the British Isles."
Question: What is the passage mainly about?
Options: (A) The results of global warming. (B) Changes in the British bird population. (C) Increasing environmental pollution. (D) Worsening British weather.
Example Output: B

Example Input: Article: Shakespeare's Sister Let us imagine, since facts are so hard to come by, what would have happened had Shakespeare had a wonderfully gifted sister, called Judith. Shakespeare himself went, very probably -- his mother was an heiress -- to the grammar school, where he may have learnt Latin -- Ovid, Virgil and Horace -- and the elements of grammar and logic. He was, it is well known, a wild boy who poached rabbits, perhaps shot a deer, and had, rather sooner than he should have done, to marry a woman in the neighborhood, who bore him a child rather quicker than was right. That escapade sent him to seek his fortune in London. He had, it seemed, a taste for the theatre; he began by holding horses at the stage door. Very soon he got work in the theatre, became a successful actor, and lived at the centre of the universe, meeting everybody, knowing everybody, practicing his art on the boards, exercising his wits in the streets, and even getting access to the palace of the queen. Meanwhile his extraordinarily gifted sister remained at home. She was as adventurous, as imaginative, as curious to see the world as he was. But she was not sent to school. She had no chance of learning grammar and logic, let alone of reading Horace and Virgil. She picked up a book now and then, one of her brother's perhaps, and read a few pages. But then her parents came in and told her to mend the stockings or mind the stew and not moon about with books and papers. They would have spoken sharply but kindly, for they were practical people who knew the conditions of life for a woman. Soon, however, before she was out of her teens, she was to be engaged to the son of a neighboring wool stapler . She cried out that marriage was hateful to her, and for that she was severely beaten by her father. Then he ceased to scold her. He begged her instead not to hurt him, not to shame him in this matter of her marriage. He would give her a chain of beads or fine dresses, he said; and there were tears in his eyes. How could she disobey him? How could she break his heart? The force of her own gift alone drove her to it. She made up a small parcel of her belongings, let herself down by a rope one summer's night and took the road to London. She was not seventeen. The birds that sang in the woods were not more musical than she was. She had the quickest fancy, a gift like her brother's, for the tune of words. Like him, she had a taste for the theatre. She stood at the stage door; she wanted to act, she said. Men laughed in her face. The manager -- a fat, loose-lipped man -- howled with laughter. He roared something about puppies dancing and women acting -- no woman, he said, could possibly be an actress. She could get no training in her craft. Could she even seek her dinner in a bar or roam the streets at midnight? Yet her genius was for fiction and lusted to feed abundantly upon the lives of men and women and the study of their ways. At last -- for she was very young, oddly like Shakespeare the poet in her face, with the same grey eyes and rounded brows -- at last Nick Greene the actor-manager took pity on her; she found herself with child by that gentleman and so -- who shall measure the heat and violence of the poet's heart when caught and confined in a woman's body? -- killed herself one winter's night and lies buried at some cross-roads where the omnibuses now stop outside the Elephant and Castle. That, more or less, is how the story would run, if a woman in Shakespeare's day had had Shakespeare's genius.
Question: What can we infer from Judith's teen life?

Example Input: Article: The International Olympic Committee named a short list of five cities as possible hosts for the 2012 Olympics. The five--London, Madrid, Moscow, New York and Paris--became official candidates, beginning a 14-month race that ended with the selection of a winning bid by the IOC's assembly in Singapore in July 2005. Havana, Leipzig, Rio de Janeiro and prefix = st1 /Istanbulwere the victims in 2004, as the field was cut down from nine applicants. Geography would appear to favor a European city after the 2008 Summer Games in Asia--Beijing and the 2010 Winter Games in North America--Vancouver. IOC president Jacques Rogge said the list could be further cut in the next month if any of the bidding cities fall short of IOC expectations. "What we have done today is retain five cities which we believe will deliver, but we will have to check if they do deliver," said Rogge. "I do not like the word 'rejection' and this in no way reflects that we do not trust these countries. " The nine original competitors launched their bids in January, 2004 with the emphasis on agreement and easily accessible venues . Favorites Paris and London promoted the attractions of their landmarks, Madrid promised an environmentally friendly Games while New Yorkcalled itself the "world city". Paris bid organizers said they would stage beach volleyball at the foot of the EiffelTowerand host many of the events at two clusters on the edge of the French capital. "Our experience with previous bids has taught us a great deal about the needs and aspirations of the IOC," Parisbid chief Philippe Baudillon said. "We firmly believe thatPariswill meet those needs." London organizers countered it by promising to hold the beach volleyball competition in Horse Guards Parade. Seventeen sports, including athletics and swimming, would be staged at a new venue in the city's deprived East End. "I am very pleased that Londonhas been named a candidate city for the 2012 Olympic Games. But I am not surprised we have cleared this most important hurdle," British Prime Minister Tony Blair said in a statement.
Question: Why is the 2012 Olympics likely to be held in a European city?

(C) Geographically speaking, it's time to hold the 2012 Games in a non-Asian and non-American country. (D) European cities turn out to be more suitable to host the 2012 Games.
