Write a multi-choice question for the following article, with the given choices and answer: Article: Between 1996 and 2010, according to a study published in 2012, the use of computed tomography (CT) scans nearly increased by three times as much, from 52 scans per 1,000 patients to 149 scans per 1,000 patients. And those images certainly provided valuable information to help doctors diagnose hidden conditions that wouldn't have been possible without the added insight. But CT scans produce those detailed images using small amounts of radiation, and while the risk of that exposure is small, on a population level, increased reliance on the scans could drive a slight bump in cancer risk from CT. That's exactly what the latest study, published in the British Medical Journal, found. It's the largest study to date -- involving 10.9 million Australians born between 1985 and 2005. A team of researchers from Australia and Europe studied the cancer rates of Australian patients from birth to 19 years old who had CT scans in early childhood, and compared them to those who did not receive the scans. Most of the cases were followed for 10 to 17 years, and by the end of the study period, 3,150 of the 680,000 patients exposed to CT scans during childhood and young adulthood developed cancer and 57,542 of the remaining participants, who were not exposed, developed cancer. Those who were scanned had a 24% greater risk of cancer than those who did not receive them, with the risk increasing by 16% for each additional CT. The risk was highest for children who received scans before age five; they showed a 35% increased chance of developing a cancer during the study period than those who weren't scanned at this age. That research is still ongoing, however, and in the meantime, doctors and patients are left to find the delicate balance between how necessary scans are to diagnose disease, and their potential risk of causing cancer, which, most experts say, is still very small. "All parties, including patients and families, need to work together to make sure that CT scans are limited to situations where there is a definite ... Options: A They came from both Australia and Europe. B Most of them are between 10 to 17 years old. C Some of them had developed cancer at the age of 19. D About 10.22 million of them hadn't received CT scans. Answer: D About 10.22 million of them hadn't received CT scans. Question:
Ans: What can we learn about the participants of the study?

Write a multi-choice question for the following article, with the given choices and answer: Article: Much of the value mothers and fathers bring to their children is due to the fact that mothers and fathers are different.And by cooperating together and complementing each other in their differences,they provide these good things that samesex caregivers cannot provide. Mothers and Fathers Play Differently Fathers tend to play with,and mothers tend to care for,children.While both mothers and fathers are physical,fathers are physical in different ways. Fathers are rough while mothers are gentle.Fathers encourage competition;mothers encourage equity.One style encourages independence while the other encourages security. Both provide security and confidence in their own ways by communicating love and physical intimacy. Fathers Push Limits;Mothers Encourage Security Go to any playground and listen to the parents.Who is encouraging their kids to swing or climb just a little higher,ride just a little faster,throw just a little harder?Who is yelling,"Slow down,not so high,not so hard"?Of course,fathers encourage children to take chances and push limits and mothers protect children and are more cautious. Joined together,they keep each other in balance and help children remain safe while expanding their experiences and confidence. Mothers and Fathers Communicate Differently A major study found that when speaking to children,mothers and fathers are different.Mothers will simplify their words and speak on the child's level.Men are not as inclined to modify their language for the child simply. Children who do not have the chance to meet both will not learn how to understand and use both styles of conversation as they grow. These boys and girls will be at a disadvantage because they will experience these different ways of communicating in relationship with teachers,bosses and others. Mothers and Fathers Discipline Differently Educational psychologist Carol Gilligan tells us that fathers stress justice,fairness and duty,while mothers stress sympathy,care and help.Again,either of these parenting styles by themselves is not... Options: A to introduce a famous educational psychologist to readers B to report the different roles mothers and fathers play in childdevelopment C to explain the natural state of mothers and fathers D to show children's agreement on parents' differences Answer: B to report the different roles mothers and fathers play in childdevelopment Question:
Ans: The main purpose of writing the passage is .

Write a multi-choice question for the following article, with the given choices and answer: Article: New findings show that musical training affects the structure and function of different brain areas, how those areas communicate during the creation of music, and how the brain interprets and combines sensory information. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. These views suggest potential new roles for musical training including training plasticity in the brain, offering an alternative tool in education, and treating a range of learning disabilities. Today's new findings show that long-term high level musical training has a broader effect. Researchers found that musicians have a better ability to combine sensory information from hearing, touch, and sight. The age at which musical training begins influenced brain structure and its function. Beginning training before the age of seven has the greatest effect. Even older adults who took music lessons as children but haven't actively played an instrument in decades have a faster brain response to a speech sound than those who never played an instrument, according to a study appearing November 6 in the Journal of Neuroscience. The finding suggests early musical training has a lasting, positive effect on how the brain deals with sound. "Playing a musical instrument is a multi-sensory and motive experience that creates emotions and movements--from finger tapping to dancing -- and engages pleasure and reward systems in the brain. It has the potential to affect brain function and structure when done over a long period of time," said Gottfried Schlaug, MD, PhD, of Harvard Medical School, press conference speaker, also an expert on music. "As today's findings show, musical training brings about new processes within the brain, at different stages of life, and with a range of effects on creativity, cognition , and learning," he added. Options: A Older People and Musical Training B Musical Training Affects Brain Structure and Its Function C Long-term High Level Musical Training D Brain Interprets and Combines Sensory Information Answer: B Musical Training Affects Brain Structure and Its Function Question:
