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.

Article: When people who are nature lovers worldwide wish all humans to realize the importance of their natural surroundings, many Australians are turning caring for the environment into a way of life. Julie, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia's Brisbane in April, one can still watch colorful blooming flowers in Julie's little garden, as she tells that in her community,"Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden." "Gardening is the most popular club in our community," she says. "A lot of retired people don't just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year." Talking about her people's sense of caring for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog's waste. "In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass," says Julie with a smile. "Taking care of the dog's waste can also help to develop children's sense of responsibility!" As to protecting water resources, the Australian government has made strict rules for families. Julie says, "We certainly would not use tap water to water the flowers!" She says almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, including car washing and watering the garden. This year, they also asked people to connect the water tank with their toilets.
Question: Why can flowers be seen all year round in Julie's community?
Options: (A) Families are taught how to take care of their gardens. (B) Gardening lessons are often given by professors. (C) The local government provides free gardening training. (D) There is enough rainwater to water the flowers regularly.

Article: The UN Security Council was created in 1945. It is made up of 10 rotating members and five permanent members, which have a veto, the power to stop a resolution . Most UN members now consider the organization's structure outdated. But any changes need the agreement of two-thirds of the 191 members, and no veto from any of the five permanent council members. Last year, Japan, Germany, Brazil and India formed a lobbying group to get permanent council seats. But North and South Korea have doubts about Japan, Italy opposes Germany for a seat, Pakistan is against India's candidacy and Mexico and Argentina Brazil. A wave of emotion swept through China last week as millions voiced their opposition to Japan's permanent membership of the United Nations (UN) Security Council. By last Friday over 22 million Chinese had signed an online petition against Japan's bid for a permanent seat on the council. According to major Chinese websites, such as sina.com, more than 170,000 overseas Chinese also signed. This is the first online activity of its kind. The petition was started by US-based Alliance for Preserving the Truth of the Sino-Japanese War . They want Japan to apologize for crimes during World War II. The group also plans to present the petition to the UN this autumn. Chinese Foreign Ministry spokesman Liu Jianchao said he didn't think the petition shows anti-Japanese feeling. He believed instead it is a request for Japan to take a responsible attitude towards history.
