They are a mixture of black, yellow, and white in such a wide variety of patterns that no two individuals look exactly alike. African wild dogs are widely distributed across the African plains but they do not live in jungle areas. They are social animals, living in groups of usually from 2 to 45 individuals. A hierarchy exists within the group, but the animals are friendly to one another. The young and the infirm are given special privileges within the group. African wild dogs use their sense of sight, not smell, to find their prey. They can run up to 55 km/h for several kilometers. In eastern Africa, they mostly hunt Thomson's gazelles, but they will also attack calves, warthogs, zebras, impalas, and the young of large antelopes such as the gnu. Growing human populations have decreased or degraded the African wild dog's habitat and also diminished their available prey. Road kill and human persecution have also had a negative impact on African wild dog populations. This species is also _ to a variety of diseases such as distemper, which is controlled in domestic .dogs. Conservation of the African wild dog's natural habitat must have the highest priority, as these dogs suffer in habitats modified by human intrusion . Question: From the passage we can conclude that _ . - African wild dogs are completely different from domestic dogs in size, weight - African wild dogs are living in groups - African wild dogs use their eyes mostly when sleeping to guard - African wild dogs use their noses to find their food in most cases

Q: Read the following article and select the best answer. Article: The long, lonely voyage of the Japanese ghost ship is over. A US Coast Guard cutter poured cannon fire into an abandoned Japanese ghost ship that had been drifting since last year's tsunami , sinking the vessel into waters more than 305 meters deep in the Gulf of Alaska and removing the danger it posed to shipping and the coastline on Thursday. The cutter's guns tore holes in the 164-foot Ryou-Un Maru, and then it began to take on water and lean to one side. In about four hours, the ship disappeared into the sea, said Chief Petty Officer Kip Wadlow. The ship had no lights or communications system, and its tank was able to carry more than 7,570 liters of diesel fuel. Officials, however, didn't know exactly how much fuel was aboard. "It's less risky than it would be running into shore or running into other ships," coast guard spokesman Paul Webb said. The US National Oceanic and Atmospheric Administration and the Environmental Protection Agency studied the problem and decided it is safer to sink the ship than let the fuel evaporate and pollute the sea environment. Ryou-Un Maru was probably among the first wave of the 1.5 million tons of garbage of refrigerators, washing machines, televisions, roofs and fishing nets heading toward North America since last March when a magnitude-9.0 earthquake struck Japan. As the coast guard was ready to fire on the vessel, a Canadian fishing vessel, the 19-meter Bernice C, claimed the rights to save the ghost ship in international waters. Plans to sink it were paused so the Canadian crew could have a chance to take the stricken ship. A Canadian official with knowledge of the situation told the Associated Press that the Bernice C was unable to drag it. Then the Canadian boat left, and once it was about 10 kilometers from the Japanese vessel, the Coast Guard began to fire, first with 25 mm shells, then a few hours later with ammunition twice that size. State officials have been working to test the danger of garbage including materials affected by a damaged nuclear power plant,... Question: Which of the following could be the best title for the passage? - Japanese ghost ship arriving at US - Tsunami garbage heading to US - Japanese ghost ship polluting the Pacific - Cannon fire sinking Japanese ghost ship
A: Cannon fire sinking Japanese ghost ship

Q: Read the following article and select the best answer. Article: Albert was an ordinary worker in an oil company in America. His workmates gave a nickname "Four dollars a bucket " to him, for he was always used to leaving an advertisement of his company "Four dollars a bucket of oil" below his name whenever and wherever he wrote down his name. As time went by, people forgot his real name. Later, when Rockefeller, the board chairman of the oil company, heard of it, he was very surprised, so he invited Albert to come to his office. "Some people give you a nickname for 'Four dollars a bucket'. Why aren't you angry?" asked Rockefeller with some puzzlement in his eyes. "Oh! Mr. Rockefeller! I like this nickname very much, because 'Four dollars a bucket' is our company's advertisement. As long as someone calls me 'Four dollars a bucket' once, I think it's a free advertisement for our company. I have no reason to get angry. Don't you think so, Mr. Rockefeller?" "Oh! What a fantastic man!" Rockefeller said excitedly when hearing Albert's words. "Young man, work harder! You must succeed in the future! I believe in you!" Five years later, Albert became the second board chairman after Rockefeller. Later Albert said in one of his reports, "I don't think we should feel frustrated when we have no way to do the world-shaking things. We should treat every thing actively because maybe our future success will begin from a small thing!" Question: Why wasn't Albert angry at his nickname? - He could become famous. - He liked to have a nickname. - It could make his workmates happy. - It could advertise for his company for free.
A: It could advertise for his company for free.

Q: Read the following article and select the best answer. Article: Today, when a man steps on to the moon, or something new and important happens, the world learns about it immediately. What did the newspapers say about that first flight in 1903? Strangely enough, they said hardly anything about it at all. There are only a few reports about it in the papers. These reports said very little. Some of the things they said were not even correct. In 1904 the Wrights built a second machine. They called it " _ No. Two". They invited some reporters to a field near Dayton to watch them fly. Unfortunately, there was some mechanical trouble with the plane and it did not fly at all that day. The newspapermen went away. They were disappointed and did not come back. The Wrights went on with their work. In 1905, they built an even better machine, "Flyer No Three". They were able to stay upon the air for half an hour and more in the machine. Farmers and travelers on the road around the Dayton often saw them flying, but when three people told newspapermen about it, they refused to believe them. The Wrights offered "Flyer No. Three" to the United States government. The government was not interested. They seemed to think the Wrights wanted money in order to build a plane. They did not understand the Wrights had already done this, and flown it as well. Experts were still saying that mechanical flight was impossible. At the end of 1905, the two brothers took their planes to pieces. The parts were put into a huge wooden box. It seemed nobody was interested. Question: The U.S. government could not understand that _ . - the Wrights had already built a machine that could fly - experts still thought flight was impossible - the Wrights wanted more money to build an airplane - "Flyer No. Three" was now in a wooden case
A: the Wrights had already built a machine that could fly
