I'm taking a test and have to guess the right answer to the question after the article. Article: Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a physical object. This is now possible with the help of 3D printers. Such machines were once used just by universities and big companies, but now, stores with 3D printing services are appearing around the United States. Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The store is filled with tools like a laser cutter, an industrial sewing machine and 3D printers. The Jaycoxs offer 3D printing classes and services for anyone who is interested. "I think 3D printing is going to be huge. It's going to have a huge effect on society as a whole." One of the students in a recent class was KiChong Tran. He plans to open a 3D printing business in Cambodia. 3D printing services are becoming available for American consumers. The UPS Store is a nationwide retailer ( ) that provides shipping, copying and other services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke Jones owns one of the stores in San Diego. "The demand has been amazing. It's been much more than I would have imagined." The UPS Store plans to add 3D printers in three more stores. At The UPS Store, the cost of the object depends on the amount of materials used. The store charges up to $95 an hour to design the object with computer software that creates a digital file to guide the printer. Mr. Jaycox predicts that within five years, 3D printing technology could become more popular. But KiChong Tran says even current technology can make a difference in a developing country like Cambodia. "With 3D printing, you can give them tools; you put it in their hands so they are responsible more for their own development and they learn skills beyond just learning English and becoming a tour guide or something like that or working at a bank; you can actually create things that give value to the world." He says it's not just in Cambodia but anywhere where there is a 3D printer that it can turn a good idea... Question: The attitude of KiChong Tran towards the development of 3D printing technology is _ Options: A: positive B: objective C: uncertain D: critical

I'm taking a test and have to guess the right answer to the question after the article. Article: Robert Spring, a 19th century forger , was as good at his profession that he was able to make his living for 15 years by selling false signatures of famous Americans. Spring was born in England in 1813 and arrived in Philadelphia in 1858 to open a bookstore. At first he make some money by selling his small but genuine of early U.S. autographs . Discovering his ability at copying handwriting, he began imitating signatures of George Washington and Ban Franklin and writing them on the title pages of old books. To make less the chance of detection , he sent his forgeries to England and Canada for sale and circulation . Forgers have a hard time selling their products. A forger can't approach a respectable buyer but must deal with people who don't have much knowledge in the field. Forgers have many ways to make their work look real. For example, they buy old books to use the aged paper of the title page, and they can treat paper and ink with chemicals. In Spring's time, right after the Civil War, Britain was still fond of the Southern states, so Spring invented a respectable maiden lady known as Miss Fanny Jackson, the only daughter of General "Stonewall" Jackson. For several years Miss Fanny's economic problems forced her to sell a great number of letters and manuscripts belonging to her famous father. Spring had to work very hard to satisfy the demand. All this activity did not prevent Spring from dying in poverty, leaving sharp-eye experts the difficult task of separating this forgeries from the originals. Question: According to the passage, forgeries are usually sold to _ . Options: A: sharp-eyed experts B: persons who aren't experts C: book dealers D: owner of the old books

I'm taking a test and have to guess the right answer to the question after the article. Article: The days of Europeans relaxing in the cafe with a newspaper and a seemingly endless cup of coffee appear to be numbered.A new English expression is popular in Europe these days:"coffee to go." "Five or ten years ago it was much more normal to sit in a cafe for several hours than it is nowadays,"says Joann,who works in a central Berlin coffee bar owned by the Canadian coffee and bakery chain Tim's. "There is a trend towards a more fast-paced life.But people still act surprised when you ask if the coffee is'to go'.You mean I can take it with me? they ask.." "Europe is often five or eight years behind trends in America,"says Joann."In the States.'coffee to go'is part of everyday life." Owing in part to Starbucks,it appears to be very much part of everyday life in many other countries too. The Seattle-based group compete with a growing number of global chains in attempting to reshape coffee drinking cultures in regions including Asia and the Middle East. The US is the model for continental Europe's new"coffee to go"culture:Each of the new cafe bars offers bagels,muffins,brownies and cookies to go with the coffee. But then,"coffee to go''might sound a little odd to English ears used to the words "takeaway"or take one. It does sum up the brisker pace of life since the city resumed its status as the German capital following the fall of the Berlin wall in 1989. As one more sign of the changing times,one of Berlin's most venerable coffee houses,cafe Einstein,has followed the trend by opening a small chain of coffee shops across the city. Taking coffee,slowly and in decorous surroundings,has been a feature of European coffee houses,particularly in German speaking countries,for decades. For the elderly citzens of Vienna it amounts to a ritual when they gather in coffee houses around the city for a cup of their favovrite drink and a piece of rich,creamy cake. Question: Every new cafe bar offers some_to go with the coffee Options: A: food B: newspaper C: drink D: music
