Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. The photograph shows a tall, blond young man holding what looks like a musical score. His eyes scared, his shoulders rounded and slightly turned away, he appeared to avoid contact with the camera. Found several weeks ago on a windy road beside the sea on the Isle of Sheppey in Kent, England, he was dripping wet and apparently very disturbed. He would not answer questions or speak with anyone. He was wearing a black suit and a white shirt, but since all the labels had been mysteriously cut out from his clothes, authorities had no way of even identifying his nationality. Since then he has continued to remain silent, refusing or unable to give information about who he is or where he comes from. He was taken to the accident and emergency department at the Medway Maritime Hospital in Gillingham, but later was moved fo the psychiatric clinic in Dartford, where he continues to baffle doctors. A spokesman for the hospital says that the first clue to his identity came when someone in the hospital had the idea of leaving him with a piece of paper and pencils and he drew a detailed sketch of a grand piano. Hospital staff then took him to the hospital’s chapel, which contains a piano. He sat appearing calm and relaxed for the first time since he had been found. According to reports from the hospital, he is also a good musician and a pleasure to listen to, even if he tends to play rather melancholy music. One staff member identified a piece from Tchaikovsky’s Swan Lake, but acknowledged that she was not an expert in classical music. According to a social worker assigned to the case, the young man is shy in the extreme and avoids any kind of social interaction. Though interpreters in various northern and central European languages have been called to the hospital to visit him, he has failed to respond to any of them. His photograph has been circulated in newspapers around the world. prompting hundreds of phone calls to the Missing Persons Bureau. However, none of these has provided useful information about his identity. There is, of course, the delicate question of whether the man is really in need of psychiatric care or just pretending to be ill. Doctors at the hospital say that they have no reason not to take him seriously and they have a duty to care for him as long as he needs it. Trả lời câu hỏi dưới đây:What can we say about the doctors?
