input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Scientists are learning new things about Antarctica, the coldest place on Earth. For example, the Antarctic ice sheet is shrinking. A new study found that summer ice loss in parts of Antarctica was at its highest level in 1,000 years. The study showed that Antarctic ice was melting mostly from below ice shelves, where the water is warmer than the ice. Eric Rignot is an earth system expert at the University of California, Irvine. He also works for the American space agency, NASA. There he serves as senior research scientist at NASA's Jet Propulsion Laboratory, also in California. He says ice melting from below is responsible for 55 percent of the shelf loss from 2003 to 2008. That is a much higher rate than scientists thought earlier. Professor Rignot and his team used satellite observations, radar and computer models to measure features above the ice to learn what was going on below. The measurements show differences from one area to the next around the continent. The major ice shelves are called Ross, Filchner and Ronne. They make up two-thirds of Antarctica's ice shelves. But they are responsible for only 15 percent of the melting ice. The professor says even small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf. Sixty percent of the Earth's fresh water is held in the huge Antarctic ice sheet. Professor Rignot says the study will help experts predict how the continent reacts to warmer ocean waters and helps to cause rising sea levels around the world. The study was published in the journal Science. Options: A Ice melting from below is responsible for 35 percent of the shelf loss from 2003 to 2008. B The major ice shelves are called Ross, Filchner and Ronne, which make up one-third of Antarctica's ice shelves. C Sixty percent of the Earth's fresh water is contained in the huge Antarctic ice sheet. D Summer ice loss in Antarctica was at its highest level in 1,000 years. Answer: C Sixty percent of the Earth's fresh water is contained in the huge Antarctic ice sheet. Question:???

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Mona Lisa, the mysterious woman in Leonardo da Vinci's 16th century masterpiece, had just given birth to her second son when she sat for the painting, a French art expert said on Tuesday. The discovery was made by a team of Canadian scientists who used special infrared and three-dimensional technology to study the paint layers on the work, which now sits in the Louvre museum in Paris. Bruno Mottin of the French Museums' Center for Research and Restoration said that on very close examination of the painting it became clear that the Mona Lisa's dress was covered in a thin transparent gauze veil. "This type of gauze dress was typical of the kind worn in early 16th century Italy by women who were pregnant or who had just given birth. This is something that had never been seen up to now because the painting was always judged to be dark and difficult to examine," he told a news conference. "We can now say that this painting by Leonardo da Vinci was painted in memory of the birth of the second son of Mona Lisa, which helps us to date it more precisely to around 1503."The young woman with the ambiguous half smile has been identified as Lisa Gherardini, wife of Florentine merchant Francesco de Giocondo. She had five children. "People always wrote that Mona Lisa had allowed her hair to hang freely over her shoulders. This greatly surprised historians because letting your hair hang freely during the Renaissance was typical of young girls and women of poor virtue ," he said. The team had hoped to discover more details about Leonardo's painting techniques, which the artist used to create a hazy effect. But scientist John Taylor said the team had been disappointed by the lack of brush stroke detail on the painting. Options: A a woman of poor virtue B da Vinci's second wife C a woman who was pregnant D the wife of Florentine merchant Answer: D the wife of Florentine merchant Question:???
output answer: According to the latest research, Mona Lisa was _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: The United States is one of the few countries in the world that has an official day on which fathers are honored by their children. On the third Sunday in June, fathers all across the United States are given presents, treated to dinner or otherwise made to feel special. However, the idea for creating a day for children to honor their fathers began in Spokane, Washington. A woman by the name of Sonora Smart Dodd thought of the idea for Father's Day while listening to a Mother's Day sermon in 1909. Having been raised by her father, Henry Jackson Smart, after her mother died, Sonora wanted her father to know how special he was to her. It was her father that made all the parental sacrifices and was, in the eyes of his daughter, a selfless and loving man. Sonora's father was born in June, so she chose to hold the first Father's Day celebration in Spokane, Washington on the 19th of June, 1910. In 1924 President Calvin Coolidge declared the third Sunday in June as Father's Day. Roses are the Father's Day flowers: red to be worn for a living father and white if the father has died. When children can't visit their fathers or take them out to dinner, they send a greeting card. Traditionally, fathers prefer greeting cards that are not too sentimental(, ). Most greeting cards are too special so fathers laugh when they open them. Some give heartfelt thanks for being there whenever the child needed Dad. Options: A Sonora honored her father on her father's birthday B Sonora's birthday was June 19 C it was decided by the president at that time D her mother died on June 19 Answer: A Sonora honored her father on her father's birthday Question:???
output answer: At first, Father's Day was fixed on June 19th because _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: We're all connected. You can send an e-mail message to a friend, and your friend can pass it on to one of his or her friends, and that friend can do the same, continuing the chain. Eventually, your message could reach just about anyone in the world, and it might take only five to seven e-mails for the message to get there. Scientists recently tested that idea in a study involving 24,000 people. Participants had to try to get a message forwarded to one of 18 randomly chosen people. Each participant started by sending one e-mail to someone they knew. Recipients could then forward the e-mail once to someone they knew, and so on. Targets, who were randomly assigned by researchers from Columbia University in New York, lived in 13 countries. They included an Australian police officer, a Norwegian veterinarian, and a college professor. Out of 24,000 chains, only 384 reached their goal. The rest petered out, usually because one of the recipients was either too busy to forward the message or thought it was junk mail. The links that reached their goal made it in an average of 4.05 e-mails. Based on the lengths of the failed chains, the researchers estimated that two strangers could generally make contact in five to seven e-mails. The most successful chains relied on casual acquaintances rather than close friends. That's because your close friends know each other whereas your acquaintances tend to know people you don't know. The phenomenon, known as the strength of weak ties, explains why people tend to get jobs through people they know casually but aren't that close to. So, start networking and instant messaging now. As they say in show business: It's all about who you know. Options: A 5 to 7 B 18 C 13 D 384 Answer: A 5 to 7 Question:???
output answer:
If you want to get into touch with a stranger in the world, how many e-mails might it take for the message to reach him/her?
