Question: Write a multi-choice question for the following article: Article: The place is England. The year is 1928. One of the founding theorists of quantum mechanics , Paul Dirac, is scratching his head because solutions to his equations have _ unexpected results. For the solutions to make sense, he reasons, there must be a particle that has the mass of an electron but the opposite charge. At the time, such a thing was not known to exist. Several years pass before American physicist Carl Anderson observes a "positive" electron, or positron that confirms Dirac's prediction. Antimatter , as the name implies, can be described as the opposite of ordinary matter. Every particle in the universe has characteristics such as mass and charge. With antimatter, the mass remains constant, but the sign of the charge is reversed. All particles have an antimatter counterpart , even the chargeless neutron . Unlike matter, antimatter is not common. Unless you're in the upper atmosphere, or inside a particle accelerator, you're not going to come across it. "Antimatter was not always so rare," Stephane Coutu, Penn State particle physicist says. There was a time when it was as prevalent as matter itself. "Right after the Big Bang ," Coutu explains, "we believe there must have been exactly the same amounts of matter and antimatter...and yet owing to some small asymmetry in the laws of particle interactions, all of the antimatter and most of the matter in the early universe was annihilated . We are left today with the resulting matter-dominated universe." Science fiction is rife with tales of high-energy particle annihilation, and indeed, antimatter weapons have appeared in current bestselling novels. This is unrealistic, Coutu says. "[It] would be very impractical owing to very great difficulties in producing and maintaining significant amounts of antimatter." Technology that uses the properties of antimatter is actually feasible outside of science fiction, however. Positron emission tomography (PET) is a medical technique that can be used to detect cancer, measure blood flow and detect coronary...

[Q]: Write a multi-choice question for the following article: Article: It never occurred to Sun Yukun that the decision he made four years ago would have an impact on his career. When the 22-year-old entered college in 2009, he decided not to change his rural residence to a students' collective one. But when he finished college and was offered a job with a state-owned enterprise in Beijing, Sun was told that he couldn't accept the offer unless he had an urban hukou (household registration record). This time, he had no choice but to change his residence status. Transferring hukou to a university became optional in 2003, and many students are confronted with the dilemma of whether to do so or not. Professionals suggest they make the decision based on their current situation and future plans. 'I regret transferring my hukou' Wang Jinbi, 20, is an accounting major at Beijing Union University. Coming from Chifeng, Inner Mongolia autonomous region, she transferred her hukou when she enrolled at university. "I didn't think it was a big deal," Wang says. "Since I'm registering under an urban hukou, it doesn't matter whether it's in Beijing or Inner Mongolia, I thought." What Wang didn't expect, however, is that she would regret her decision later. "After two years of study, I've figured out my future plans. I want to return to my hometown and make a living there," she says. That means Wang needs to transfer her hukou back again, which she worries will be a troublesome procedure. "I have a friend who graduated last year. She spent a lot of time and energy transferring her hukou back to her hometown again due to complicated paperworks," says Wang. Guidelines for transferring hukou Wang's experience is not uncommon. Many students don't know what their decision means for their future. In order to help these students, Xie Yongqiang, from the Chengdu Municipal Bureau of Justice, posted a guideline for transferring hukou on a micro blog. According to Xie, students should firstly think about where they're going to stay. "If you like the city where you're studying and are considering staying...

input: Please answer the following: Write a multi-choice question for the following article: Article: For most of my 15 years, my father usually said very little to my mother and me. He preferred reading the newspaper or watching football matches on television to talking to his family. Everything changed one morning. As soon as I came downstairs to breakfast, I could see that he wasn't his usual reserved self. "Can't wait! FIFA World Cup! Big match! Must see!" I quickly figured out what all the excitement was about: Dad is a big football fan. I had never been interested in football, but Dad's excitement that morning made me more and more curious. I had to find out why this sport was making my normally reserved father act like a five-year-old on his first trip to Disneyland. Dad decided that we should all eat at a little German restaurant so that we could watch the World Cup while eating. Secretly, I think he was hoping to turn Mum and me into football fans. The match started a few minutes after we entered the restaurant. As I was eating my meal, a loud noise came from the television. Surprised, I looked up at the TV: "Why is that man jumping up and down?" Dad patiently explained: "That's Papa Bouba Diop, my son. It's normal for them to jump up and down after they've scored." Dad explained almost everything to me. His monosyllabic answers were a thing of the past. I loved the new Dad! I watched the rest of the match, becoming more and more interested. When I told my father that I planned to watch more matches with him, he smiled and gave me a wink . At long last we had something in common. Football has really helped Dad and me get closer and form a stronger relationship with each other. Who says football is only about 22 men running after a silly ball?
