[EX Q]: Article: The television news feature about Ben Heckmann, an eighth grader from Farmington, Minn, was breathless in its praise. "At 14, he has accomplished something many adults can't achieve," the reporter said, "Ben is a twice-published author." But Ben's two "Velvet Black" books, describing a fictional rock band, were not picked from a pile of manuscripts by an eagle eyed publisher. They were self-published, at the cost of $400 by Ben's parents. Over the past five years, print-on-demand technology and a growing number of self publishing companies whose books can be sold online have inspired writers of all ages to avoid the traditional gatekeeping system for determining who could call himself a "published author." The mothers and fathers who foot the bill say they are simply trying to encourage their children, in the same way that other parents buy equipment for a promising baseball player. But others see self-publishing as a lost opportunity to teach children about hardship and perseverance. Mr. Robbins, a critic, thinks it is wonderful to start writing at a young age, but worries self-publishing sends the wrong message. "There are no prodigies in literature," he said. "Literature requires experience, in a way that mathematics and music do not." Alan Rinzler, a publishing industry veteran, suggested parents hire a professional editor like him to work with their child to tear a manuscript apart and help make a better. Ben's father, Ken, said Ben's ambitions "weren't to knockHarry Potteroff the list," but "to get that good feeling inside that you've done something." Ajla Dizdarevic, 12, who has self-published two books of poetry, has been on television and in local newspapers. "Being a published author," she said, "was always a dream of mine." Her new dream: three books by age 15.
Question: Which of the following is true of Ben?
Options: (A) He has achieved something unusual for his age. (B) His self-published books were well received. (C) His manuscripts were favored by the publisher. (D) He was thought little of by the public media.

[EX 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.

[EX Q]: Article: A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. Jet lag interferes with a person's normal times for sleeping and waking. People with jet lag may feel extremely tired for several days. They also may have problems thinking clearly and remembering. Kwangwook Cho is a researcher at the University of Bristol in Britain. He reported the findings of his jet lag study in the publication Nature Neuroscience. The study involved twenty young women who worked for international airlines. The women had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas. Mister Cho took some fluid from the women's mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains using magnetic resonance imaging. This is a way to measure the size of the brain's temporal lobes. It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones. Mister Cho says he believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory. Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently affect memory.
