input: Please answer the following: Write a multi-choice question for the following article: Article: A study made by University of Sussex found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain . The researchers said : " Simultaneously , using mobile phones , laptops and other media devices could change the structure of our brains . " Worryingly , the part of the brain that shrinks is involved in processing emotion . The finding has linked multi-tasking with a shortened attention span , depression , anxiety and lower grades at school . The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology . This could mean sending a text message while listening to music and checking email , or speaking on the phone while watching TV and surfing the web . The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex ( ACC ) . The findings held even when differences in personality were taken into account . The study , published in the journal PLOS ONE , is the first to make a link between multi-tasking and the structure of the brain . Researcher KepKeeLoh said : " Media multi-tasking is become more popular in our lives today and there is growing concern about its impacts on our cognition and social-emotional well-being . " He added that more researches are needed to prove that multi-tasking shrinks the brain . This is because it is also possible that people with less grey matter in the ACC are more likely to use lots of devices simultaneously . Scientists have previously described brain structure can be altered on prolonged exposure to new environments and experience . Other studies have shown that training - such as learning magic or taxi drivers learning the map of London - can increase grey matter densities in certain parts .

Please answer this: Write a multi-choice question for the following article: Article: Parents at one Connecticut elementary school say they are angry over the use of so-called "scream rooms" to discipline special needs students. The two rooms at Farm Hill Elementary School in Middletown, Conn., came under fire after several students complained about the sounds of children yelling coming from the rooms, while building keepers reported having to clean up blood and urine from their floors and walls. Tricia Belin, whose two children attend the school, described the rooms as 6-by-4-foot space with concrete walls used to isolate special needs students who are disruptive in the classroom. "Closet is pretty much what it is," Belin said and her children are regularly subjected to "screaming"coming from inside the rooms. Belin said she complained to the school's principal when she first learned about them last October, and was told they were considered and "alternative learning environment," but he did not say whether students were placed in them alone or with a teacher. Shawn Archer, whose 10-year-old daughter also attends the school, said parents were never notified about the rooms and claims his child and others are fearful of them. Board of Education Chairman Gene Nocera acknowledged in an interview that the reports about the rooms were "disturbing" and said school officials were investigating their use. "We understand the parents' concerns and we take their concerns very seriously," Nocera said. "We want to be sure our students are being treated safely." He stressed that under school policy, no child is to be left alone at any time. He said the school district is looking to give more resources to the school, including hiring full-time psychologists and providing more training to all the teachers.

input question: Write a multi-choice question for the following article: Article: For the kids in Matt Marciano's sixth-grade social studies class, Thanks-giving is a time for great ideas. "We look at different foods that people eat around the world," says Marciano. "The lesson," he explains, "teaches students to admit that some people are unlucky. And it also gets them thinking about Thanksgiving, about their lives, and about their biggest homework of the year--to find a way they can change the world." Last year, 12-year-old Christian D. taught basic soccer skills to 63 kids with cancer. Christian's classmate Brianna used the money she had raised to buy 56 teddy bears. She donated them to a woman's shelter. Both students say the experience taught them something they'll never forget: When we give something to others, we're really giving thanks. And giving thanks feels good. "Helping the woman smile, if just for a day, made me feel like I could make a difference," Brianna says. "And it taught me that I should always be thankful for what I have." Brianna's happiness is something Jeffrey Froh knows about. Froh studies how gratitude affects a person's mind and attitudes. Those who are thankful are more likely to help others. Grateful people and kids in particular are healthier and happier than those who are not. "Grateful kids tend to be happier and more satisfied with their lives," Froh says. "Kids who give thanks are happier with school, their families and their friends. Grateful children also feel less envy toward others, are less likely to be depressed and even do better in school." "To experience gratitude," says Froh, "a couple of things have to happen. First you have to notice that there is goodness in your life. Then you have to admit that the reason for that goodness lies partially outside of yourself."???
