input: Please answer the following: Write a multi-choice question for the following article: Article: There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century. In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India.In order to reduce fraud , he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay.This finding inspired him to begin investigating fingerprints.In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system.Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist . Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system--the first existence. Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system.In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, _ matched Rojas' exactly.She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy . It's still used in many Spanish-speaking countries. Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In...

Please answer this: Write a multi-choice question for the following article: Article: Have you ever seen a 250-mile-wide bath sponge? Well, take a look at Hyperion, one of Saturn's moons. Recent photos of the hamburger-shaped moon reveal a strange world covered with large and small craters . The photos were taken by high-tech cameras aboard the spacecraft Cassini, which has been exploring Saturn and its moons since 2004. Scientists studying the photos have recently identified something surprising: dark and reddish material on Hyperion's surface. They believe that the substance may be organic material, including combinations of the chemical elements hydrogen and carbon. That's important because all life, including human life, is built from organic building blocks. "Organic material is the key to understanding life in the solar system. When we try to understand how life formed on Earth and whether life could form on other planets, this is one of the things we look at," says Dr. Amanda Hendrix. She is a planetary scientist who works on the Cassini project. So how did such material get on a lifeless moon circling Saturn? Scientists suspect it was deposited by meteors . "Craters on Hyperion are the result of meteoroid impact," said Dr. Hendrix. "A meteoroid is the leftover material from the formation of planets." The largest crater on Hyperion is 75 miles across and 6 miles deep! But even though Hyperion looks like a sponge, it most likely doesn't feel like one. Cassini has found that the moon is made mainly of ice. Cassini may give scientists many more surprises. It is scheduled to orbit Saturn until next year, but NASA scientists also hope to extend the spacecraft's mission until 2010. Unlike Earth, which has only one moon, Saturn has 48 moons. The extra two years will give scientists an opportunity to learn more about Saturn's many moons. "This mission not only has given us a lot of answers but also has posed a lot of new questions," says Hendrix.

Problem: Write a multi-choice question for the following article: Article: CANBERRA (Reuters Life!) - Think twice before eating those dropped crumbs off your computer keyboard -- you might as well be eating off a toilet seat, according to a new study on the amount of germs on keyboards. A study by British "Which? Computing" asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle. Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat. "Most people don't give much thought to the grime that builds up on their PC, but if you don't clean your computer, you might as well eat your lunch off the toilet," said Sarah Kidner, the consumer magazine editor of "Which? Computing" in a statement. The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria. Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards. But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse. Almost half -- or 46 per cent -- cleaned their keyboard less than once a month. To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them.

A: Question: What do you think the expression "Think twice before eating those dropped crumbs off your computer keyboard" stands for?Options:A Think several times before eating beside your computerB Don't drop foods onto the computer keyboard.C Don't eat foods dropped onto the computer keyboard.D Be careful when you are eating by the computer.Answer:C

input question: Write a multi-choice question for the following article: Article: Since 1984, Philadelphia has been cleaning up its act. One by one, graffiti-covered walls are being changed into outdoor art. So far, more than 1,800 murals have been painted. Philadelphia now has more murals than any other American city. The walls that were once ugly with graffiti are now covered with beautiful pictures of historical heroes and modern art, thanks to the Mural Arts Program (MAP). Its work makes schools and public places attractive, and its citizens very proud. The program began as part of Philadelphia's Anti-Graffiti Network. Jane Golden is the MAP's artistic director. "When people ask me what our program is about," she says, "I answer them with one word: hope." Each year, the MAP offers youth art programs and workshops. Some one-time graffiti writers even help paint MAP murals. The MAP's work, says Golden, is all about developing a sense of community . When a neighborhood requests a mural, the MAP works with the people there to develop a message. Some messages have been "Safe Streets," "Love and Care," and "Peace Walk." The MAP receives up to 50 requests for murals each week. Last year, the workers painted 140 murals. "The making of a mural enters people's collective memory as an extraordinary, pleasant moment in neighborhood history" says Golden, who began as a muralist in Los Angeles.???
