I'm taking a test and have to guess the right answer to the question after the article. Article: How "Kangaroo" Became an Animal's Name Early in the 18th century, Captain Cook, a famous explorer of Australia, unexpectedly saw an unusual animal during his first visit to Australia. The animal had a large mouth-like head and jumped along on its large legs. To his surprise, the unusual animal carried its baby in a special pocket of flesh. Captain Cook pointed to the animal which was eating grass in the distance and asked his local guide what that animal was. The guide seemed not to know what he was pointing at and finally said Kang-a-roo. Cook carefully wrote down Kang-a-roo as the animal's name in his word book. The Europeans who later got to Australia were anxious to see the unusual animal "Kang-a-roo", but their requests met with puzzled looks of the local people. Before long they got to discover that the local guide who made the answer to Cook's question really meant, "I don't know what you are pointing at." Funny enough, the name "Kang-a-roo" stuck and it is still in use today. Question: Which of the following sentences best expresses the main idea? Options: A: Captain Cook's guide had a sense of humor. B: Local Australians could speak English in Cook's time. C: Some words have very funny origins. D: Captain Cook loved wild animals.

I'm taking a test and have to guess the right answer to the question after the article. Article: Since the Internet came into homes, the daily life has never been the same again. But the thing that worries most of us is that we can get viruses from the Internet. But can we catch viruses on our cell phones? A new study in the journal Science says yes, but the spread of such mobile software that can bring harm to our cell phones won't reach dangerous levels until more cell phones are on the same operating system. Computers are easily attacked by viruses because they share data, especially over the Internet. Of course, nowadays, more people are using their cell phones more and more frequently. They use them for emailing, text messaging and downloading troublesome ring tones, etc.,so it is obvious that cell phone viruses are a threat as well. Scientists used nameless call data from more than six million cell phone users to help model a possible outbreak. And they concluded that viruses that spread from phone to phone by Bluetooth are not much concerned, because users have to be in close physical relation for their phones to "see" one another. However, viruses that spread through multimedia messaging services can move much faster, because they can come in disguise , such as a cool tune sent by a friend. The good news is that to be effective, these viruses need their victims to all use the same operating system, which not enough of us do. Because there is no Microsoft operating system for mobile phones, yet. Thank goodness. Question: What can we infer about Bluetooth according to the scientists? Options: A: It can increase the chances of cell phone viruses greatly. B: It can help us to stop the spreading of cell phone viruses. C: It won't possibly cause the outbreak of cell phone viruses. D: It can make users have close physical relation with one another.

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: There are many things we can do in our daily life to reduce the amount of greenhouse gas sent out. Probably the most important is to share what you have learned with your family and friends. Use the family car less. Walk or cycle whenever possible. Take a bus. Try ride sharing. Use less energy in the house by turning down the heat when you are away or sleeping and turning off lights and electrical equipment you aren't using. If your family needs a car, make sure to buy a fuel-efficient one. An average car sends out nearly 60 tons of carbon dioxide during its lifetime, compared to between 22 and 30 tons from a fuel-efficient car. Encourage your family to use the car more efficiently : for example, check the air in the tires. Underinflated tires can increase fuel use by 8%. Turn the car off instead of letting it run when it is stopped. Idling uses more gas and sets free carbon dioxide into the air, Reuse, recycle and compost (... ) your waste. It takes much less energy to reuse or recycle a product than to make a new one. Correctly composting your food and yard waste removes the methane that they would cause at the landfill site. Buying less is al- ways the best. Plant trees. Trees take in carbon dioxide, reduce pollution, provide shade, and look great. Question: A fuel-efficient car gives of _ tons of carbon dioxide during its lifetime less than an average car. Options: A: 22-30 B: 30-38 C: 60 D: 8-30
