The machine looks similar to an ordinary printer and can print a "statue" in about 90 minutes after scanning anything, including a person. The printer prints layer by layer. For example, if we want to print a 30-cm-tall statue, the computer will calculate* the layers and print 460 layers in total*. It can also print people and clothes. You can stand for scanning for just about three minutes, and a statue will be finished about two hours. The cost for a statue of a man is about 1000yuan. The printer, which costs about 500,000yuan, is from the USA. "We want to introduce this technology to people, and find more chances here." said an engineer, "There is a company in USA that offers 3D printing services to people. Many people come to design their own thing. It is very cool. We hope that the printer will encourage more Chinese people to be more creative." Question: A 3D printer _ . Answer:

Question: Read the following article and answer the question. Article: What do you do if you're stranded on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane. Body signals Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side. Smoke signals The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke. Ground-to-air signals It's a good idea to build some signals, too. Use large pieces of wood to make the symbols . If you can't find any wood, use earth. Some useful symbols are: F "I need food and water." II "I need medicine." I "I am badly hurt." X" I am unable to move from here." Pilots' replies If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.) However, there is no signal which means "message not received". Why not? Question: What is the passage mainly about? Answer:
OPTIONS:
- The explanation of building signals on an island.
- The importance of making signals on an island.
- Ways of sending out signals on a lonely island.
- Ways of receiving signals from a lonely island
