Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: HARTLAND, Wis. (AP) -- Lauren Panos was surprised when she walked into her ninth-grade English class in the fall and saw there were no boys. Her parents had not told her they had enrolled her in a new all-girls class at Arrowhead High School in Hartland. Panos still isn't sold on the idea. "All the girls there, they can talk out of turn," the 14-year-old said. "We are bored of tasks and it's really upsetting." More public school systems are looking at separating boys and girls, whether for certain classes or by total schools, after the federal government opened the door last fall. Supporters say separating students by sex helps them learn better and allows boys and girls to explore subjects they may not otherwise take. "Boys just make a bigger trouble in the class," Panos' classmate, Alyson Douglas, 15, said "I likes not worrying about boys causing _ ." Presently, nationwide, at least 253 public schools offer single-sex classes and 51 schools are entirely single sex, according to the National Association for Single Sex Public Education. In1995, just three public schools offered single-sex classes. Critics of same-sex classrooms argue that proven methods of improving education should be carried out instead of one that divides boys and girls. "Too many schools feel they can carry out a social experiment with students' education with really the weakest of theories," said Emily Martin, deputy director of the American Civil Liberties Union's Women's Rights Project. Single-sex schools are an "illusionary silver bullet," said Lisa Maatz, director of public policy and government relations for the American Association of University Women. They distract from real problems and do not offer proven solutions such as lower class sizes and enough funding, she said. "I would suggest that for many of our kids and families, especially in Milwaukee, it's a question of choice," Spence said. "We have a series of choices in Milwaukee and I just think this should be one additional choice." Options: A Panos thinks that the idea is very good for they can talk freely. B Panos doesn't accept the fact that girls in her class have to finish many tasks. C Panos doesn't like the idea that boys and girls are in separate classes. D Panos prefers to study in a class in which there are only boys. Answer: C Panos doesn't like the idea that boys and girls are in separate classes. Question:

The answer is:
From what Panos said we can learn that _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: More than 2.25 billion cups of coffee are drunk throughout the world each day, and it's likely that many taste bitter. Now, a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups. Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes biter was true. They used 36 volunteers and three different colored cups---blue, white and transparent glass--- to examine the claim. In one experiment, the white cup increased the intensity of the coffee taste relative to the transparent cup. Then, in a second experiment, coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups, while the blue cup made the coffee taste the sweetest. The scientists believe that the color brown may be associated with bitterness, and coffee in a white cup appears the brownest. "Our study clearly shows that the color of a cup does influence our sense of the coffee taste," leading author Dr George Doorn, wrote in an article for The Conversation. "The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups," he said. "The potential effects may spell the difference between a one-time purchase and a return customer." Actually, the idea that color can change the food and drink taste came out many years ago. A study published last year reported that red, strawberry-flavored cake served on a white plate was rated as 10 percent sweeter than the same food presented on a black plate. Options: A the popularity of sweet coffee. B an experiment made in Oxford. C the effect of cup color on coffee's taste D useful tips on how to make coffee. Answer: C the effect of cup color on coffee's taste Question:???
output answer: The passage is mainly about _ .

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Japanese professor Yoji Kimura believes laughter is a weapon that in healthy doses can end the world's wars. To measure it, the expert on communications has invented a machine to chart out laughter--and a new unit of "aH" to calculate it. "We have found that children laugh more freely, releasing 10 aH per second, which is about twice as much as an adult," Kimura, a professor at Kansai University in the western city of Osaka, told reporters. "Adults tend to calculate whether it's appropriate to laugh and under those restraints they eventually forget how," he said. "Laughing is like a restart function on a computer. Laughing freely is very important in the course of human development," he said. Kimura, who believes in "a change from a century of wars to a century of humor and tolerance," has studied the science of laughter for decades in Osaka. In his theory, human laughter is produced in four emotional stages. "I believe there is a circuit in the human brain that creates laughter," Kimura said confidently. To measure laughter, he attaches sensors on the skin of a tested people's stomach, particularly the diaphragm , and detects muscle movements. "I have a theory that humor detected in the brain gets directly released through the movement of diaphragm," he said. By checking the movement of the diaphragm and other parts of the body, it will be possible to see if a person is only pretending to laugh while also telling different types of laughter, Kimura said. Kimura wants to make the measuring device as small as a mobile phone and possibly market it as a health and amusement device. Kimura said he planned to present his findings this summer to the US-based International Society for Humor Studies, adding that he looked forward to looking at differences in laughter internationally. Options: A Because they are busy with their work. B Because they are affected by some factors. C Because they use computers too often. D Because they don't think it good to laugh much. Answer: B Because they are affected by some factors. Question:
