Read the following article and select the best answer. Article: There's no pizza on Mars, but scientists have found a solution to this problem for hungry astronauts: a pizza printer! NASA, the American space agency, has developed a machine that "prints" food. They showed a model of the printer in Austin, Texas last month. How does it work? Cartridges filled with powdered dough , cheese, sauce, water and oil put the ingredients layer by layer onto a printer bed. The printer bed, which gets hot from below, cooks the food as it's being printed. Since most of the ingredients are powdered, they can be sent into space and stored for many years without going bad. Water makes food go sour, so the food powders are mixed with water and oil only when they are being printed. "Long-distance space travel requires more than 15 years of shelf life for food." says Anjan Contractor, whose company developing the printer. " We take water out, and in that form, food will last maybe 30 years." In outer space, there are far fewer choices for astronauts for dinner. Most of their foods--even things like beef or shrimp--are eaten from bags as powders . Scientists hope the new food printer can be used to make more delicious food in outer space, keeping astronauts healthier and happier. But the printer is not limited to use in outer space. Scientists think it could be useful on Earth, too. It could allow personal meals to be made at the dinner table, according to each person's different needs. "Let's say someone is an athlete in the family, and he needs more protein ," says Anjan Contractor, founder of Systems and Materials Research Corp, the company developing the printer. "We can design recipes for him and print out more protein-nutritious food for him." Question: What is the best title for this passage? _ - Astronauts' Life in Outer Space - Hungry?

Q: Read the following article and select the best answer. Article: Recently a Beijing father sent in a question at an Internet forum asking what "PK" meant. "My family has been watching the 'I Am the Singer' singing competition TV programme. My little daughter asked me what 'PK' meant, but I had no idea," explained the puzzled father. To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, "PK" is short for "Player Kill", in which two players fight until one ends the life of the other. In the case of the "I Am the Singer" singing competition, "PK" was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition raking. Like this father, Chinese teachers at Middle schools have also been finding their students using _ which are difficult to understand. A teacher from Tianjin asked her students to write the compositions with simple language, but they came up with a lot of Internet jargons that she didn't understand. "My 'GG' came back this summer from college. He told me I've grown up to be a 'PLMM'. I loved to 'FB' with him together; he always took me to the 'KPM'," went one composition. "GG" means Ge Ge (Chinese pinyin for brother). "PLMM" is Piao Liang Mei Mei (beautiful girl)."FB" means Fu Bai (corruption)."KPM" is short for KFC, Pizza Hut and McDonald's. Some specialists welcome Internet jargons as a new development in language. If you do not even know what a Kong Long (dinosaur, meaning an ugly looking femal) or a Qing Wa (frog, meaning an ugly looking male ) is, you will possibly be regarded as a CaiNiao! Question: The example of the Beijing father and the Tianjin teacher are used to show that Internet jargons _ . - are used not only online - can be understood very well - are welcomed by all the people - cause trouble to our mother tongue
A: cause trouble to our mother tongue
