[Q]: 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.
Question: Why does the author mention "Even older adults ... a speech sound." in Para. 3?
Options: (A) To suggest how new roles for musical training work. (B) To prove early musical training affects the function of the brain. (C) To explain how the brain interprets sensory information. (D) To show how the brain areas communicate in music training.

[Q]: Article: "How did Norman know, Sister Emma?" "He overheard you and Aryan arguing. I suspect that he purposely overheard on you. Norman knew or concluded what profession Aryan practiced. He might well have followed Aryan on his explorations. Whether he did or not is beside the point. When Aryan came back yesterday afternoon, Norman certainly decided that he had made some find, for Aryan told Norman that he would be leaving for the capital to meet the detective the next morning. He probably followed Aryan to your room and overheard what passed between you. "Since you could not act against the law of man and God, he would serve a natural justice in his own way. He took the jar of poison hemlock from the chemistry shop and when Aryan asked for a drink, he supplied it. Norman did not know the precise quantity needed and so Aryan did not suffer the full effects until after the bell called the community into the dining hall for the evening meal." Abbess was following Sister Emma closely. "And then?" "Then I began my investigation, and then the detective arrived seeking Aryan for an explanation for his death." "But who killed Norman?" "Norman knew that sooner or later he would be discovered. But more importantly in his guileless mind there was also the guilt of having taken a man's life to be considered. Norman was a simple man. He decided that he should accept the punishment--the honor-price of a life. What greater honor-price for the life of Aryan could he offer than his own? He also took a draught of poison hemlock." There was a pause.
Question: What may have happened to Aryan?
Options: (A) He was killed by poison. (B) He was found missing. (C) He was poisoned but saved. (D) He went away with what he had found.
[A]: A

[Q]: Article: Women were friends, I once would have said, when they totally love and support and trust each other, and bear to each other the secrets of their souls, and run--no questions asked--to help each other, and tell _ truths to each other(No, you can't wear that dress unless you lose ten pounds first.) when these truths must be told. In other words, I once would have said that a friend is a friend all the way, but now I believe that's narrow point of view. Friendships serve many different functions,meet different needs and range from those as all-the-way as the friendship of the soul sisters mentioned above to that of the most casual playmates. Convenience friends are women with whom we'd have no particular reason to be friends: a next-door neighbor or the mother of one of our children's closest friends. They'll lend us their cups for a party. They'll drive our kids to school when we're sick. They'll take us to pick up our car when we need a lift .As we will for them. But we don't , with convenience friends, ever come too close or tell too much; we maintain our public face and emotional distance. Special-interest friends aren't intimate ,and they needn't involve kids or cats. Their value lies in some interest jointly shared .And so we may have an office friend or a tennis friend. "I've got one woman friend," says Joyce," who likes, as I do, to take music courses, which makes it nice for me and her. I'd say that what we're doing is doing together, not being together." Crossroads friends are important for what was for the friendship we shared at a crucial ,now past, time of life. A time, perhaps, when we roomed in college together or went together through pregnancy, birth and that scary first year of new motherhood. Crossroads friends develop powerful links, links strong enough to endure with not much more contact than once-a-year letters at Christmas. And out of respect for those crossroads years, for those dramas and dreams we once shared, we will always be friends. Crossroads friends seem to maintain a special kind of intimacy ----dormant but always ready to be revived ---and though we may rarely meet ,whenever we do connect, it's personal and strong. Another kind of intimacy exists in the cross-generational friendships, the friends that form across generation in what one woman calls her daughter-mother and her mother-daughter relationships. There are good friends, pretty good friends and very good friends, and these friendships are defined by their level of intimacy. We might tell a good friend, for example, that yesterday we had a fight with our husband. And we might tell a pretty good friend that this fight with our husband made us so mad that we slept on the couch. And we might tell a very good friend that the reason we got so mad in that fight that we slept on the couch had something to do with a girl who works in his office. But it's only to our very best friends that we're willing to tell all, to tell what's going on with that girl in his office.
