[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: Ed Viesturs grew up in Rockford, Illinois, where the tallest thing on the horizon was the water tower. But on Thursday, Viesturs became the only American to climb to the top of the world's 14 highest mountains. His last hike was up Mount Annapurna, in Asia's snowcapped Himalayas. At 26,545 feet, its peak is the 10th highest in the world. It is the mountain that inspired him to start climbing. "It tends to be the trickiest, the most dangerous," said Viesturs. "There's no simple way to climb it. There are threatening avalanches and ice falls that protect the mountain." In high school, Viesturs read French climber Maurice Herzog's tale of climbing the icy Annapurna. Herzog's story was of frostbite and difficulty and near-death experiences. Viesturs was right away. Viesturs got his start on Washington's Mount Rainier in 1977, guiding hikes in the summer. Fifteen years ago, he set out to walk up to the world's highest peaks. Finally, he's done. The pioneering climber talks about mountains as if they were living creatures that should be treated with respect. "You have to use all of your senses, all of your abilities to see if the mountain will let you climb it," said Viesturs. "If we have the patience and the respect, and if we're here at the right time, under the right circumstances, they allow us to go up, and allow us to come down." What's next for a man who can't stop climbing? "I'm going to hug my wife and kids and kind of kick back and enjoy the summer," says Viesturs. But for a man who's climbed the world's 14 tallest mountains, he will probably soon set off on yet another adventure.
Question: What record has Ed Viesturs set?
Options: (A) He has succeeded in climbing to the world's 14th highest mountain. (B) He has been to the top of the world's 14 highest mountains. (C) He has become the first to climb to the height of 26,545feet. (D) He has become the first man to climb to the top of 14 highest mountains in the world.
