Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Steve Jobs, Apple's chief executive, made his first public appearance since going on medical leave six weeks ago, taking the stage at a San Francisco media event to introduce the iPad 2, the second generation of the company's tablet computer. Thin but energetic, Mr. Jobs showed off a thinner iPad. " We've been working on this product for a while and I just didn't want to miss this day," he said. His absence has concerned investors, especially since the group has given no details of his condition. He was diagnosed with cancer in 2004 and had a liver transplant during almost six moths of medical leave in 2009. People close to him said last month his health had been changing. Apple's stock rose more than 2 percent in the minutes after Mr. Jobs began speaking, then gave up some of its gain as he detailed the iPad 2. The iPad 2 will go on sale in black and white versions in the US on March 11 and in 26 other countries, including the UK and Germany, on March 25. The table is Apple's biggest product launch since the iPhone three years ago, and is comparable to the iPhone as the most expected in Apple's history. Most of the improvements in the latest version had been expected, including front and rear-facing video, which allows video conferencing between iPads, Mac computers and the most recent iPhones and iPods, a larger speaker, a faster processor and other upgrades. The iPad 2 is one-third thinner than the original tablet and slightly lighter, with a 9.7-inch touchscreen. It can run movies, books, games and a complete range of applications. In the US it will work with AT&T and Verizon, the top two mobile carriers. The pricing will be the same to the 2010 iPad at its introduction, ranging from $499 to $829 in six models. But Apple dropped prices on the older iPad on Wednesday by $100 across the board. Apple has made the most of its year-long head start in tablets, selling 15,000,000 units of the older iPad last year and taking about 85 percent of the market. Forrester predicted that the iPad 2 would clain 80... Question: What makes Apple's tablets superior to the competing tablets of other companies? Options: A: the low price B: the Android software C: the full kinds of models D: the tens of thousands of applications

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The behavior of a building's users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions by 80 percent by 2050, part of which will be achieved by all new homes being zero carbon by 2016. But this report shows that sustainable building design on its own--though extremely important--is not enough to achieve such reductions: the behavior of the people using the building has to change too. The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency, _ instead focus on architectural and technological developments. "Technology is going to assist but it is not going to do everything,"explains Katy Janda, a UKERC senior researcher, "consumption patterns of building users can defeat the most careful design." In other words, old habits die hard, even in the best designed eco home. Another part of the problem is information. Households and bill payers don't have the knowledge they need to change their energy use habits. Without specific information, it's hard to estimate the costs and benefits of making different choices. Feedback facilities, like smart meters and energy monitors, could help bridge this information gap by helping people see how changing their behavior directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters. Social science research has added a further dimension, suggesting that individuals' behavior in the home can be personal and cannot be predicted--whether people throw open their windows rather than turn down the thermostat , for example. Janda argues that education is the key. She calls for a focused program to teach people about buildings and their own behavior in them. Question: The information gap in energy use _ . Options: A: affects the study on energy monitors B: brings about problems for smart meters C: can be bridged by feedback facilities D: will be caused by building users' old habits
A: C

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Without proper planning,tourism can cause problems.For example,too many tourists can crowd public places that are also enjoyed by the inhabitants of the country.If tourists create too much traffic,the inhabitants become annoyed and unhappy.They begin to dislike tourists and to treat them impolitely.They forget how much tourism can help the country's economy.It is important to think about the people of a destination country and how tourism affects them.Tourism should help a country keep the customs and beauty that attract tourists.Tourism should also advance the wealth and happiness of local .

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: About 400 high school students from Western Pennsylvania and the neighboring state of Ohio joined a heated discussion recently on "China: What Does the Future Hold?" "It's either going to turn out really good or really bad - who knows?" said Braveen Ragunathan, a senior from an Ohio high school. In his mind all Americans are connected to China in some way. The forum was held in Pittsburgh, once a US industrial center, now facing job-cuts because of competition brought about by globalization. The aim of the forum is to help American students learn more about the outside world. Elliott Blackwell, a junior at the Neighborhood Academy, said the forum let him know more about how China's economic development will affect America in the future. Some students, although impressed by China's economic boom, expressed uneasiness about the nation's practices and differences from the American way of doing business and politics. "China is a power coming up,so they might challenge us," Paul Amon, a junior from Oil City High School, said. "I'd hope that China can be our partner but I think that we'd clash along the way because we're too different," he added. George Riley, a teacher explained: "The view of China is usually negative and I think that's fueled by the media." However, some negative feelings are not from the media. Merri Ebel is a senior at East Allegheny High School north of Pittsburgh. Both her parents lost their jobs recently. The company they worked for said it was cheaper to produce goods in China rather than the US. "China is just this big question mark. China was just a big country with millions of people that no one really knew about because it was so far away and our class was more American history based," she said. For better or worse US teenagers are eager to know more about China, the forum shows. Question: Which of the following from the passage is true? Options: A: The view of China is usually positive. B: The forum is not necessary at all. C: The US and China would clash along the way because we are too big. D: US teenagers are eager to know more about China.
