Read the following article and select the best answer. Article: You may not be aware, but digital currency is a big part of the Internet world. QQ Coins can buy you accessories for your QQ images. More importantly, a new digital currency, Bitcoin, is bringing the world's commerce online. If you're traveling, you can spend Bitcoins at restaurants and hotels listed at BitcoinTravel.com. In China, Bitcoins can be used to buy goods at about 134 online shops on Taobao. And at a cafe named 2nd Place in Beijing, you can even buy fresh coffee with Bitcoins. So what makes Bitcoin so attractive to investors? First of all, the Bitcoin system is not controlled by anyone. One central authority cannot make policies to change the value of Bitcoins. The fixed amount of Bitcoins also means they cannot lose value through inflation , as all forms of paper money have done over time. In addition, accounts in the Bitcoin system are anonymous and transparent. Users can set up an account easily and track every Bitcoin. All of these features seem to make Bitcoins immune from loss, but that is not entirely true. "The value of Bitcoins can vary wildly as no central government makes the price of them steady. If the value drops suddenly, investors cannot get any compensation ," Zhao Qingming, a senior researcher at China Construction Bank, told China Economic Weekly. And Bitcoins, unlike company shares, are not backed by any tangible funds, which also adds to their risk. While China will not recognize the digital currency anytime soon, Xinhua said, lawmakers and officials at a hearing on Nov. 18 in the US made positive comments about Bitcoin. Ben Bernanke, outgoing chairman of the Federal Reserve, told the Washington Post that "these types of creations, such as Bitcoin... may hold long-term promise, particularly if its system promotes a faster, more secure and more efficient payment system." Question: We can use Bitcoin to buy the following things except _ . - online goods - goods at 134 online shops on Taobao - books in physical shops - coffee at a cafe named 2nd Place
books in physical shops

Ques: Read the following article and select the best answer. Article: prefix = st1 /Britainis facing a sharp rise in its rat population as growing numbers of people leave fast food scraps in the street , an environment group warned . Keep Britain Tidy said the rodents were stopping their traditional hunts underground and were roaming the streets ,tempted by discarded burgers ,pizzas and crisps. "The rat population is on the rise and soon it'll be as common to see a rodent on our street as it is to see a dog or a cat," said group Director ,Sue Nelson. The practice of dumping fast food litter and scraps on the street rather than in the trash-with young men the worst offenders-was behind the rise. According to the National Rodent Survey in 2005, Britain's rat population has grown by nearly one quarter since 2000 and is now estimated at 60 million , two million more than the human population. On average a rat can give birth every 24--28 days and just a single pair of rats can produce a colony of 2,000 a year. Around 200 people a year get Weil's Disease----an infection which can lead to liver or kidney failure and eventually death and which is arrived in rat's waste. To highlight the issue , Keep Britain Tidy launched a cinema ad entitled "How close do you want them to get?" The advertisement gave a shocking image of a young woman sleeping in a bed of rots, echoing the nightmare scene from James Herbert's classic horror tale The Rats, in which mutant rodents begin to prey on humans. Question: By writing the passage, the author tries to _ . - close some of the burger and pizza restaurants - draw the public attention to the problem of rats - prevent the rats from growing up - make advertisement for the classic horror film The Rats
Ans: draw the public attention to the problem of rats
