Write a multi-choice question for the following article: Article: Every electronic gadget needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts. Now, scientists in California say they have come up with a way to turn a living cell into a memory device. It can store only one tiny bit of information, but it's a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease. Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can't be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream. If normal machines won't do the trick, perhaps biology will. Scientists who work in the field of synthetic biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information. This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive. In the new experiment, the researchers turned DNA from bacteria into a switch. They "flip " a small section of DNA. Then, using the same procedure , the scientists flip the section again--returning it into its normal structure. Using these DNA switches, "We can write and erase DNA in a living cell," bioengineer, Jerome Bonnet, explained to Science News. It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory--less than what a computer uses to remember a single letter. "This was an important proof that it was doable,"...

Q: Write a multi-choice question for the following article: Article: In 1883. John Roebling was inspired by an idea to build a spectacular bridge connecting New York with the Long Island. However, bridge building experts throughout the world thought this was an impossible feat and told Roebling to forget the idea, but Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he managed to convince his son Washington, an up and coming engineer, that the bridge in fact could be built. The project started well, but when it was only a few months underway a tragic accident on the site took the life of John Roebling. Washington was injured and left with a certain amount of brain damage, which resulted in him not being able to walk or talk or even move. "We told them so." "Crazy men and their crazy dreams.'' "It's foolish to chase wild visions." Evcryone had a negative comment to make and felt that the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap, Washington was never discouraged. One day he was lying on his bed in hospital, seeing the sky and the tops of the trees outside for just a moment with the sunlight streaming through the windows, and a gentle breeze bowing the flimsy white curtains apart when an idea hit him. He decided to make the best use of the only finger he could move. Thus, he slowly developed a code of communication with his wife. He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. It seemed foolish but the project was under way again. For 13 years Washington tapped out his instructions with his finger on his wife's arm until the bridge was finally completed.
A: Question: What can we learn about Washington's wife?Options:A She could understand Washington and helped him a lot.B She cnuldn't understand him but took good care of him.C She didn't like Washington's idea about building the bridge.D She took the responsibility to continue building the bridge.Answer:A

Write a multi-choice question for the following article: Article: As Amy Hagadorn rounded the corner across the hall from her classroom, she crashed with a tall boy from the fifth grade running in the opposite direction. "Watch it, Squirt," the boy yelled, as he dodged around the little third grader. Then, with an unfriendly smile on his face, the boy took hold of his right leg and mimicked the way Amy limped when she walked. Amy closed her eyes for a moment. --Ignore him, she told herself as she headed for her classroom. But at the end of the day, Amy was still thinking about the tall boy's mean teasing. It wasn't as if he were the only one. Amy was tired of it. Sometimes, even in a classroom full of other students, the teasing about her speech or her limping made her feel all alone. Back home at the dinner table that evening Amy was quiet. That's why Patti Hagdorn was happy to havesome exciting news to share with her daughter. "There's a Christmas Wish Contest on the radio station," she announced. "Write a letter to Santa and you might win a prize. I think someone at this table with blond curly hair should enter." Amy giggled. The contest sounded like fun. She started thinking about what she wanted most for Christmas. A smile took hold of Amy when the idea first came to her. Out came pencil and paper and Amy went to work on her letter. --Dear Santa Claus, she began. While Amy worked away at her best printing, the rest of the family tried to guess what she might ask from Santa. Amy's sister, Jamie, and Amy's mom both thought a 3-foot Barbie Doll would top Amy's wish list. Amy's dad guessed a picture book. But Amy wasn't ready to reveal her secret Christmas wish just then. Here is Amy's letter to Santa, just as she wrote it that night: Dear Santa Clause, My name is Amy. I am 9 years old. I have a problem at school. Can you help me, Santa? Kids laugh at me because of the way I walk and run and talk. I have cerebral palsy . I just want one day where no one laughs at me or makes fun of me.
