Question: Read the following article and answer the question. Article: Cooks at the Qingfeng Steamed Bun Shop in west Beijing can't make the pork and scallion baozi (buns) fast enough since Xi Jinping visited for some traditional workers' food and ate it among the workers. The Chinese president's visit late last month went down a treat, while web commentators were enthusiastic in their praise for Xi's easy populism, after he left the government headquarters in nearby Zhongnanhai and ordered six steamed buns filled with pork and scallions, a bowl of stewed pig liver and a plate of green vegetables. The bill came to 21 yuan, about EUR2.50, and he sat and finished it at one of the restaurant tables, just like any other working Joe. While Xi is known as "President Xi" abroad, in China he is known as "Chairman Xi", in the same way as the country's late founding father Mao Zedong is known as "chairman Mao". The Chinese government is keen for its leaders to have the president title abroad, as it sounds, well, more presidential. But in Qingfeng, it's all about the chairman. "Since Chairman Xi came here, the restaurant has had queues like this every day. We didn't know the chairman was coming beforehand. We only recognized him when he was at the window picking up his food because he also waited in the line," says a waitress. Xi is building up a reputation as a more approachable kind of leader, a man of the people - something people in Ireland got a taste of when they saw how he handled a hurley in Croke Park during his visit. There were rumours last year that Xi even took a taxi to ask the driver what was really going on in Beijing, although that may have been a _ . While his predecessor Hu Jintao was seen as a theorist, Xi's public profile is high. Question: Which of the following statements is TRUE? _ Answer:
OPTIONS:
- Xi's arrival was arranged ahead of time.
- "President" and "chairman" are the same titles overseas.
- Chairman Mao queued in the same restaurant.
- Present Xi was good at food in Ireland during his visit.
Answer: "President" and "chairman" are the same titles overseas.

Question: Read the following article and answer the question. Article: This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu oil mixed with 80% conventional jet fuel. What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions from airplanes. there are a lot of hurdles that still need to be overcome. First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet'A'fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same. The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter - the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up. However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae produced in sewage treatment plants, not from food sources. Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project. While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen! Question: .Why does Virgin Airlines try to replace normal fuel with biofuel? Answer:
OPTIONS:
- To cut down the flight cost of the company.
- To remove some hurdles for the biofuel to work.
- To reduce CO2 emissions from airplanes.
- To test plane engines on biofuel.
Answer: To reduce CO2 emissions from airplanes.

Question: Read the following article and answer the question. Article: One in 400 children in the United States has diabetes . And the most difficult thing for the young diabetic patients is that many of them don't have a clear idea when they need to take insulin(a drug used in treating diabetes).The parents of one Long Island boy found the perfect solution--Hero, a specially trained dog that can discover when a diabetic is in trouble and find help.

Hero's trainer, said the dog could discover the slightest changes in blood sugar by her sense of smell."Humans have 5 million smell receptors ; dogs have 5 billion smell receptors,"she said. When the dog discovers something's wrong, she'll rub her head against Johnny's legs. If he doesn't answer her, Hero knows to look for Johnny's mom and dad. Hero even could ring up 911. On their first night, Johnny's was comfortably sleeping in his own bed with Hero and not with his parents for the first time.
