input question: Write a multi-choice question for the following article: Article: Crime in the city of prefix = st1 /Cliohit a 30-year low last year. "This is ly wonderful for our citizens, our businesses, and our visitors," said Police Chief Louis Gates. Clio has a population of 28,000, but it has at least 30 gangs . The gangs make most of their money from dealing drugs and offering "protection." They also commit violent crimes, such as stealing, robbery or even murder. There were 1,486 thefts last year. Most of the thefts involved cars. Thieves also robbed the people at gunpoint or pick pocketed them. They broke .into houses and businesses at the alarming rate of two a day two years ago, but that rate was down to only one a day last year. "That's a 50-percent decrease in one year," said Gates. "I think the police officers deserve a big pat on the back. Even better, maybe they'll get that 10-percent raise that they are all hoping for. " With an example of how the police force has helped reduce crime, Gates talked about bicycle thefts. "For years and years, kids were locking up their bikes at bike stands in front of schools, libraries, and shopping mails. About 10 percent of the time, the kids would come out of the school or wherever and discover that their bike was no longer there. We wracked our brains( ) trying to find a solution to this problem. Finally, at the beginning of last year, when we simply removed most of the bike stands, then the bicycle theft rate came down quickly. Most cities in the state have similar problems. They all involve too many people, too much crime, too few police, and too little money. These problems go along with civilization everywhere. They might reduce, but they will probably never disappear. All people can do is hope for the best and prepare for the worst.???
output answer: Question: The police force has helped reduce the bicycle theft rate by _ .Options:A removing most of the bike standsB asking kids to lock up their bikesC setting up more public bike standsD asking kids to park their bikes in front of schoolsAnswer:A

Write a multi-choice question for the following article: Article: For a long time, people who fish have had to rely on luck to catch fish. Even big fishing ships, fitted out with radar and modern equipment, have their share of bad days. Wouldn't it be nice if fish could be trained to come at the call of a whistle the way some days are trained? Well, the days of "fish whistle" may be just _ . Japanese companies are working on methods that will train fish to return to harvest areas at the sound of an underwater whistle. The method works like this: First, fish eggs are hatched in a laboratory. Whenever feeding time arrives, a whistle sounds. The young fish learn to return to their feeding areas at the sound of the whistle. Later, the fish are set free at sea, near special-made under water "barns". There, the whistle-plus-feeding program continues. Being well fed and sheltered, the fish continue to live around the barn. So when fishing time arrives, all the harvesters need to do is to sound the whistle, drop their nets, and draw in a lot of fish. Many countries have closed their offshore fishing waters to ships from other countries. With fish whistle and barns, Japan hopes to become less dependent on importing fish from other countries.

Q: Write a multi-choice question for the following article: Article: A mother had two daughters. She loved them very much, but two girls would fight with each other from their earliest years. As they grew older, they became total strangers. They had no contact with each other when they were adults. This caused the mother great pain. Then, later, she had an idea. She decided to write a letter to them. In this letter, she told them how much she loved them, and how she wanted them to love each other in this way. She also gave them news of herself and some guidance on how to live happier lives. When the letter was ready, she wrote out one copy for each daughter, but these copies were special. Each copy contained only every second sentence of the original letter: the copy for one daughter had only the even sentences, and the other daughter's copy contained only the odd sentences. Neither contained the fullness of the mother's message. When the two daughters received their letters, they were puzzled. To understand the half-letter, they would have to put the two letters together and read them as one, which meant they must approach one another again in love and respect. But they each blamed the other for not helping them when trying to read the half-letter. For a long time, the mother waited in vain. Then one day, when the mother had almost given up hope, there was a knock at the door. There they stood, together. "We've come home," they said at the same time. "We've finally put our letters together, and we've come to say how much we love you, Mum." Then she hugged them both, tears of joy streaming down her cheeks, and welcomed them back home.
A: Question: The mother gave her daughters incomplete letters mainly to _ .Options:A win their heartsB offer them adviceC tell them her newsD mend their relationsAnswer:D

Problem: Given the question: Write a multi-choice question for the following article: Article: Everyone has those nights-you lie in your bed for hours, tossing and turning, totally unable to fall asleep. You wish you could just turn your brain off as if it were a light. That would make things much easier, wouldn't it? Now it looks like you are one step closer to this wild dream of yours-scientists from Oxford University, UK have just discovered the "switch" that tells the brain to go to sleep, reported Forbes. To understand the study, you first need to know that there are two mechanisms that regulate sleep. There's one that we're already familiar with --our body clock, which works in a 24-hour cycle based on the light changes throughout the day. The other one is what scientists call the sleep "homeostat ". This mechanism has nothing to do with daylight. Instead, it keeps track of the brain's waking hours and urges it to rest if it has been awake for a long time. "It is similar to the thermostat in your home. A thermostat measures temperature and switches on the heating if it's too cold," Professor Gero Miesenbock, who led the study, told The Telegraph. Our bodies use both of the mechanisms to regulate sleep. "The body clock says it's the right time, and the sleep thermostat has built up pressure during a long waking day," explained Miesenbock. There is no way that scientists can trick the body clock. But with the sleep homeostat, there might be something they can do. The researchers found that the sleep homeostat works by activating a specific group of nerve cells, or neurons, in the brain. They tested their theory on fruit flies by removing the neurons from the insects' brains. And as expected, they found that the flies without the homeostat neurons did not keep a regular sleep pattern anymore. Now that scientists have pinpointed the exact place in the brain-- or, the "switch"--that regulates sleep, they can begin investigating how to activate these cells at any given time so that people can be sent to sleep instantly. More importantly, figuring out how sleep mechanisms work may also help us to one...

Question: What can we conclude from the article?Options:A Generally, the sleep homeostat has less effect on people during the day than at night.B There is little scientists can do to affect the way the sleep homeostat works.C What makes us go to sleep at night is probably a combination of the two mechanisms.D The more homeostat neurons there are in one's brain, the more easily one can fall asleep.Answer:C
