[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: You've heard of 3D printing from newspaper and TV programs. It can "print" in plastic, metal, nylon, and over a hundred other materials. 3D printing technology has been around since the 1980s, it was not widely used until the early 2010s. The first working 3D printer was created in 1984 by Chuck Hull. 3D printers use many different types of technologies, but they all share one thing in common: they create a three-dimensional object by building it layer , by continuing layer, until the whole object is completed. Imagine a baker lay down each layer one at a time until the whole cake is formed. 3D printing is somewhat similar, but just a bit stricter. How can 3D printers work so well? The most important thing-a program, a 3D printer also needs to have instructions for what to print from a computer. It needs a file as well. The file which is a Computer Aided Design (CAD) paper is created with the use of a 3D modeling program. The program creates a paper that is sent to the 3D printer. Along the way, software pieces the design into hundreds, or more likely thousands of layers. The 3D printer builds up one layer at a time, from the bottom to the top, until the object is done. 3D printings can be used for making many kinds of things such as machine parts, daily life objects, even human organs using a person's own cells. Nowadays, Marc. Dillon founds a project which deals with many world famous paintings like Leonardo da Vinci's Mona Lisa, Van Gogh's Sunflower with 3D technology. This project helps the blind people enjoy the fantastic art through touching. In order to provide a good user experience, these 3D paintings have special instruments which can tell people what they touch. Options: A 3D printers use 3 types of technologies. B 3D printers make printings from the top. C 3D printers work as a baker makes a cake. D 3D printers piece the design into a few layers. Answer: C 3D printers work as a baker makes a cake. Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Wars and traffic accidents can leave people with terrible physical and mental _ Often they appear again in dreams. Now American researchers think they are close to developing a pill , which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce , or possibly erase the effect of sad memories. In November, some scientists tested a drug on people in the US and France. The drug stops the body producing chemicals that fix memories in the brain. So far the research has suggested that only the mental effects of memories may be reduced, not that the memories are erased. The research has caused plenty of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. "Some memories can destroy people's lives. They come back to you when you don't want to have them in a dream. They usually come with very sad feeling." said Roger Pitman, a scientist of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering." But those who are against the research say that it is very dangerous to change memories because memories give us our identity . They also help us all get away from the mistakes of the past. "All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to erase those memories," said Rebecca Dresser. Options: A Some memories can destroy people's lives. B People want to get away from bad memories. C Experiencing bad events makes us different from others.
