[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."

[Q]: Article: Three key facts about rising sea levels need to be pointed out to the world's politicians and planners: sea-level rise is now unavoidable, it will happen faster than most of us thought, and it will go on for a very long time. Even greenhouse gas emissions stopped tomorrow, the oceans will continue to become larger as they get warm. The climate scientists estimate that sea-level rise may be in the range of 1 to 2 meters by 2100, with a small risk of an even greater rise. For many islands and low-lying regions, even small rises will cause disasters. But for most countries, the problem is what has been built on that land: New York, Sydney and Tokyo, to mention just a few cities. Unless something can be done, great areas of urban network will disappear under the waves. It will take a great engineering effort to protect these cities---an effort that may be beyond economies that have been brought to their knees. None of this means we should fear, and stop trying to forbid emissions. But together with these efforts, we need to start acting now and we must stop building in danger zones. Billions of dollars are being spent on constructing homes, offices and roads in _ coastal areas. For instance, the skyscrapers of Shanghai are being built on land that is merely 4 meters above sea level on average, and they are sinking under the weight of the buildings. Therefore, planning for new coastal developments is to go against reality. If we want to build a lasting heritage for our children, we should do so on the plentiful land that is in no danger from the sea. It is one of the effective ways to slow down climate change, and we should be acting on it now.
Question: Which of the following about sea-level rise is true?
Options: (A) It will be brought under control by 2100. (B) It will cause few problems to many islands. (C) It may become worse than we expected. (D) It may be caused by fast urban development.
