Q: 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.

Q: Article: Surface Exploration. Robots make great explorers on planets,moons,and other landing areas. Aside from earth,just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient for humans to breathe,making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand .Plus there would be complications with radiation,weather,and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions. Data Collection. Robots are designed for collecting scientific data. Robots are also able to perform many tasks at a time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals,analyzing ground samples,and finding water are all performed much quicker and more accurately by robots. Cost Effective. The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans,but also enough food and water to keep them alive for the duration of the trip. Moreover,robots have no problems working for hours on end. Robots never complain,they don't require food or water,and they never need a bathroom break. Space Travel. Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are the Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.
Question: According to the passage,which of the following is NOT true?
Options: (A) The use of robots in space exploration costs more than the use of humans. (B) It may be dangerous for humans to explore the solar system except the earth. (C) Both the Spirit and Opportunity have found the evidence of water in the Mars. (D) Many different types of robots have explored the space successfully.

Q: Article: With the new year coming, a new website was set up to offer ringtones of the sounds of dozens of rare and endangered species from around the globe. The Center for Biological Diversity started offering free wildlife ringtones for cellphones a year ago to educate people about the _ of the animals, and the campaign enjoyed such success that the environmental group has collected more ringtones and added them to its website for this year. The group plans to release a kind of new ringtones each month, including the sounds of the African elephant and the emperor penguin of the Antarctic, said Peter Galvin, the group's conservation director. "We've hit the 100,000th download in over 150 countries," Galvin said Wednesday in a telephone interview. "It's pretty interesting. We didn't realize how much of an international hit it would become." The response, he said, reinforces the worldwide movement to save endangered and rare species. Available ringtones include the howl of an endangered Mexican gray wolf, the bellows of an Arctic beluga whale and the calls of dozens of other mammals, birds and reptiles. Website visitors can also get cellphone wallpaper and facts for each of the species. And later this year, the website will be available in Spanish and more ringtones from species in Latin America will be added, Galvin said.
Question: The new ringtones mentioned in the passage are used to _ .
Options: (A) raise people' s awareness of wildlife protection (B) develop a new website (C) add fun to the new year (D) develop the cellphone industry
