[EX Q]: Article: The Dixie Chicks used to be known as the biggest-selling female group in music history. Now they are known as one of the most disputed . In 2003, Natalie Maines, the lead singer of the Dixie Chicks, was in the news. During a concert in London, she criticized President Bush for his political actions. She spoke less than two weeks before the invasion of Iraq. The Chicks did not realize the effect of those words. They soon lost their fans. They even received death threats. The comment changed the direction of their lives, music, and beliefs. Now, their new album Taking the Long Way shows their new musical direction. It is about acting and thinking freely. Maines openly sings about criticizing the president. She says she learned about herself by expressing her beliefs. The album also represents the Chicks' new musical style. In the past, they only sang songs influenced by country music. They did not always write their own music. Now, they are adding some rock sounds to their song collection, and they wrote every song on the album. Taking the Long Way quickly became the top-selling album in the country when it was released at the end of May. But many country music radio stations will not play music by the Dixie Chicks. Many people in the country music industry now oppose the band for criticizing the president. However, the Dixie Chicks continue to stress the importance of standing firmly and bravely for what they believe in --no matter what people may think or say.

[EX Q]: Article: Graham and his friends preferred to shoot up in their arms, necks and legs. A dealer once said Graham was the type who would never be able to turn back and that he expected him to die from the drug. Wendy feared the same, but didn't know how to save her son. " Once, after he'd disappeared for more than a month, I found him at a friend's house with a bunch of other users," she said, "I got down on my hands and knees, begging him to come home. He did, but the next morning he was gone. I don't know what made him do it, but I drove 20 miles to the nearest train station. Graham was headed for Seattle, his pockets full of drugs. If I hadn't gotten there in time, I would never have seen him alive again." The turning point came in 2007, after Graham was arrested yet again for possession. Wendy got a call from the Montana Drugs Project, which works with local law enforcement to keep track of youth-related crimes so it can help families in trouble. Following a counselor's advice, Wendy hired two men to come to her home in the middle of the night, tie Graham and take him to a treatment program in Thompson Falls, Montana. "I was high when they came and really angry with my mom," he said, "But if she hadn't done that, drugs would have killed me." After six months of treatment, Graham, now 19, came back to Kalispell, where he's grown close to Wendy once again. "I still have the desires every day and attend support meetings every night," he said, "But life is worth living again. My mom thinks that's a miracle. I guess she is right."
