I'm taking a test and have to guess the right answer to the question after the article. Article: The first day our professor challenged us to get to know someone we didn't know. I looked around when a gentle hand touched my shoulder. I turned around to find a wrinkled, little old lady smiling at me. She said, "Hi, handsome. My name is Rose. I'm 87. Can I give you a hug?" I laughed, "Of course you may!" and she gave me a giant squeeze. "Why are you in college at such a young, innocent age?" I asked. She jokingly replied, "I'm here to meet a rich husband, get married, and have a couple of children." "No seriously," I said. "I want to realize my dream!" she told me. Over the course of the year, Rose became a campus icon and everyone liked to listen to this "time machine". At the end of the semester we invited Rose to speak at our football banquet and I'll never forget what she taught us. "There is a huge difference between growing older and growing up. If you are 19 and lie in bed for one full year and don't do one productive thing, you will turn 20. If I am 87 and stay in bed for a year and never do anything I will turn 88. We have less time to live on. Anybody can grow older. That doesn't take any talent or ability. The idea is to grow up by always finding opportunity in change. The elderly usually don't have regrets for what we did, but rather for things we did not do." At the year's end, Rose finished the college degree she had dreamed about all those years. One week after graduation Rose died peacefully in her sleep. Over 2,000 students attended her funeral honoring the wonderful woman who taught us such an important message. Question: According to Rose, growing up is different from growing older because   _  . Options: A: growing up doesn't need as much effort or talent as growing older B: growing up means young people have enough time to waste C: there is no need for one to worry about death D: growing up means one has more chances or time to choose what one likes

I'm taking a test and have to guess the right answer to the question after the article. Article: Digital wallets have been called the future of real-world payment technology. With major players like Alipay, WecChat and Apple Pay becoming popular, it seems to be a safe bet that a change in consumer payment technology is coming soon. A recent study by Citi Retail Services found that a growing number of people are embracing digital wallets, due in large part to their convenience and ease of use , "There's no question 2016 will be an important year as digital wallets gain more acceptance.", Leslie MeNamara, managing director of partner management, Citi Retail Services, noted. Last month, CNN reporter Will Ripley experience a day in Beijing without his wallet. "In China's largest cities, you can definitely survive without carrying a pocket full of cash and credit cards- as long as you've got your smartphone," he wrote. "A huge number of businesses in Beijing accept mobile payments." He paid for breakfast by scanning a QR code on the window of a hole-in-the -wall restaurant. All he had to do was enter a password and the transaction  was completed. Then he also used his phone to pay for movies tickets, buy takeout food, order goods for delivery. In fact, he was not the only one to enjoy this convenience. His assistant Shen Lu also paid her household water bill with her mobile phone. In seconds, she was able to transfer funds( ) from one of several linked accounts. Unlike the situations in the US and other countries, "China doesn't have a really money-making credit card system". Gu Yu, co-founder of the new payment app Mileslife, told CNN. "So Chinese people just skipped credit cards and wet straight to mobile payments." Gu also pointed out the advantages of mobile payments. "No coins or bills that can be lost or stolen, electronic receipts, the ease of keeping track of spending and of course, no wallet taking up space." he said Question: What is the article mainly about? Options: A: How to survive with no cash or credit cards at hand in China. B: Differences between mobile payments and traditional cash payments. C: The increasing popularity of digital wallets in China and the reasons behind it. D: Differences in payments between America and China.

I'm taking a test and have to guess the right answer to the question after the article. Article: A car that runs on coffee is unveiled(shown to the public for the first time)today but at between 25 and 50 times the cost of running a car on petrol, the invention won't please any motor industry accountants. Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for PS400 and it was chosen because it looked like the time-traveling DeLorean in the movieBack To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules  .It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles. The team calculates the Car-puccino will do three miles per kilo of ground coffee   -- about 56 cups of espressos   per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between PS13 and PS26 a kilo depending on brand and quality, will cost between PS910 and PS1,820, or between 25 and 50 times the PS36 cost of petrol for the journey.In total, the trip will cost 11,760 espressos, and the team will have to take 'coffee breaks' roughly every 30 to 45 miles to pour in more granules.They will also have to stop about every 60 miles to clean out the 'coffee filters' to rid them of the soot and tar which is also generated by the process.So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours. Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty's Revenue and Custom haven't yet worked out how much. Nick Watson, producer of Bang Goes The Theory, said, "Coffee, like wood or coal, has some carbon content so you can use it as a fuel.The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns.The brand doesn't matter." He said the same technology could be used to power a car on other unusual... Question: The Car-puccino has its disadvantages EXCEPT that   _  . Options: A: it makes a lot of noise B: it runs at a very high cost C: it has to stop to be refueled very often D: it's not good enough for long-distance journey
