Read the following article and select the best answer. Article: Stubbornness(,) can push a business to hold on but can also kill your business if it keeps stopping you. Because I'm stubborn. I chased my dream of creating a pet-food company that sells what it claims to sell and not some unidentifiable substance in a dressed-up bag. Originally we packed our foods in transparent bags, which became our guiding philosophy. To start the company in 2003, I visited every pet-food store in Manhattan and some outside the city. By 2006 Stella&Chewy's was sold in 250 stores, mostly in New York City. In 2007 I moved the company to Wisconsin, with our earnings reaching almost $500,000 that year.But getting my product into stores was just the beginning. We were competing against much bigger pet-food companies whose monthly marketing budgets were more than our yearly sales. So we invested in advertisements and a website and even stood on sidewalks giving our samples. With more customers came more feedback , much of which I ignored, I was also receiving complaints about ice crystals on the food, which form when the air temperature changes during transport. For this reason, most frozen foods are packaged in opaque bags or boxes. Studies have proved that ice crystals have little effect on either the quality or the taste of the food. So I ignored the complaints. After all, we were better than our competitors that wouldn't even show their products. We didn't hide anything. In 2007 our sales kept growing, but not as fast as those of our competitors. We were told that new consumers were choosing products packaged in opaque bags. When I visited the stores and forced myself to consider my products objectively, I had to degree: The ice crystals reduced the look I wanted. The food looked as if a snowstorm had hit the inside of the bag. We switched to opaque bags and tried to make ice crystals smaller. Customers responded: In 2009 Stella$Chewy's was sold in 2,500 stores across the country. Question: According to the passage, ice crystals _ . - only appear on frozen food - may make pets feel uncomfortable - won't form if the foods are transported well - almost don't affect the quality of pet foods
almost don't affect the quality of pet foods

Read the following article and select the best answer. Article: Although new laws have been passed in some American states to cut down on distracted driving, many accidents and deaths were still related with it, especially using cell phones while driving. Recently the Obama administration is considering disabling cell phones in cars, aiming to out down cell-phone-related road deaths. Transportation Secretaryy Ray LaHood, the nation's anti-distracted-driving supporter, said in an interview on November 18 that federal officials are looking at technology to disable cell phones inside cars. "I think it will be done," LaHood said."I think the technology is there and 1 think you're going to see the technology become adaptable in automobiles to disable these cell phones.We need to do a lot more if we were going to save lives." Also on Thursday, the transportation government started a new "Faces of Distracted Driving" video campaign that features people who have been killed or lost their loved ones because of inattentive drivers.The video features heartbreaking stories of children killed in crashes because of phoning or text messaging, and new videos are expected to be added every few weeks. A driver is four times more likely to crash while using a mobile phone.More than 5,500 people were killed last year by distracted drivers, and another 500,000 were injured.LaHood has said it is never safe to talk on a cell phone while driving, hands-free or not, because it can really cause distraction. Incidentally, a lot of people seem to agree with this viewpoint--a new research shows nearly two-thirds of Americans support a national ban on the use of cell phones while driving, even if the driver is using a hands-free device .But the research didn't ask how people feel about government-issued mobile phone scramblers or other disabling devices. Question: The Obama administration is considering disabling cell phones in cars because _ . - there is no national laws to prevent the use of cell phones in cars - most drivers take no notice of American laws - using phones while driving has caused many accidents - cell phone technology needs to be developed
using phones while driving has caused many accidents

Q: Read the following article and select the best answer. Article: Before you go to another country, it is a great help if you know the language and some of the customs of the country. When people meet each other for the first time in Britain, they say "How do you do?" and shake hands . Usually they do not shake hands when they just meet or say goodbye. But they shake hands after they haven't met for a long time or when they will be away from each other for a long time. Last year a group of German students went to England for a holiday. Their teacher told them that the English people hardly shake hands. So when they met their English friends at the station, they kept their hands behind their backs. The English students had learned that Germans shake hands as often as possible, so they put their hands in front and got ready to shake hands with them. It made both of them laugh. Question: It is _ if you know the language and some of the customs of the country. - not useful - not helpful - very helpful - very bad
A: very helpful

Read the following article and select the best answer. Article: President Xi Jinping announced Thursday that China will cut its military by 300,000 troops, a significant reduction in one of the largest militaries in the world and a move that the Chinese leader called a gesture of peace. "The great renewal of the Chinese nation requires efforts of one generation after another," Xi said in a speech at Tiananmen Square remembering the 70th anniversary of the end of World War II in the Pacific. "Having created an impressive civilization of over 5,000 years, the Chinese civilization will lead to an even brighter future," he said. Xi's announcement came as China staged a massive military parade in central Beijing, sending a stream of troops, tanks, and ballistic missiles down a major east-west street as fighter jets flew overhead with multicolored smoke. Xi's speech kicked off the parade. An estimated 12,000 troops--about 1,000 of whom hailed from Belarus, Cuba, Tajikistan, and other countries-marched along the 10-lane Chang'an Avenue from the commercial center wangfujing to Tiannmen Square, about 1.5 miles away. They were joined by 200 fighter jets and 500 pieces of military hardware, including tanks and ballistic missiles. Representatives from 49 countries were in attendance, including Russian leader Vladimir Putin, South Korean President Park Geun-hye and U. N. Secretary General Ban Ki-moon. Rory Medcalf, head of the national security college at Australian National University, said the Beijing may have decided to cut 300,000 troops "in the name of efficiency and cost saving." Xi conducted a "troop inspection" after his speech, riding down Chan'gan Avenue in a Chinese-made Hongqi parade car. On Thursday morning, China's popular microblogging site Sina Weibo filled up with 350 million comments related to the parade. While many users expressed their love of their country and pride, few posts were filled with criticism. "The soldiers are too serious," wrote one user. Others complained about the cloud of gray exhaust that followed a column of tanks. Question: What is mainly talked about in the passage? - China decided to cut its military forces. - World leaders attended China's military parade. - China sowed its weapons to the world. - China held a military parade in Beijing.
