question:
Article: Ibrahim became disabled after contracting polio when he was three years old. At first his parents, like many other parents of disabled children in Niger, did not want to send him to school. They were worried he would be laughed at by his classmates. Despite his disability, and his parents' doubts, Ibrahim was determined to go to school. "When I was eight," Ibrahim says, "other kids of my age were going to school while I stayed at home. I did not like that. So, I pestered my parents until they finally let me go to school." Ibrahim's parents sent him to a private school nearby. Although the journey to and from school was a short one, it still wasn't easy for Ibrahim. He had to use his hands to help him move along, protecting them with plastic slippers. But at least he was getting an education. However, after only a year in school, Ibrahim's education was interrupted when his parents separated. His mother did not have the means to continue paying for his tuition. In 2007, Ibrahim received some money to be fitted with a leg brace , corrective shoes and his first pair of crutches . Now that he was more mobile than before, the most important thing for him was to find a way to go back to school. "I wanted to start school again last October," Ibrahim says. "After my mother told me she could not afford it, I went to visit some of my relatives for support. And I collected 5,000 francs CFA (US $8) to pay my tuition for half a year. I will find the rest of the money somehow." Ibrahim attends a school in which he is the only disabled student. According to his teacher, he is among the top five students in a class of 55.
Question: Why did Ibrahim's parents prefer Ibrahim to stay at home?
Options: (A) There was a lot of housework for him to do. (B) They had no money to pay for his tuition. (C) There were not enough schools in the country. (D) They were afraid the students would make fun of him.

D

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.

B
