[Q]: Article: (PARIS) ----An English tourist who was highly praised for rescuing a three-year-old boy in Paris said he didn't think twice before diving into the freezing river. Tuesday's news said 25-year-old John Smith from England was the man who left the spot quickly after the rescue last Saturday. He lifted the little boy out of the water after he fell off the bank. He handed the child to his father, David Anderson, who had dived in after him. "I didn't think at all," John told the News. "It happened very fast. I reacted very fast." John, an engineer on vacation, was walking with his girlfriend along the pier when he saw something falling into the water. He thought it was a doll, but realized it was a child when he approached the river. Immediately, he took off his coat and jumped into the water. When he reached the child, he appeared lifeless, he said. Fortunately, when he was out of the water, he opened his eyes. Anderson said his son slipped off the bank when he was adjusting his camera. An ambulance came later for him, said John, who was handed dry clothes from onlookers. John caught a taxi with his girlfriend shortly after. The rescue happened on the day before he left for England. John said he didn't realize his story had greatly moved Paris until he was leaving the city the next morning. "I don't really think I'm a hero," said John. "Anyone would do the same thing."

Options: (A) To meet his girlfriend. (B) To visit his parents. (C) To work as an engineer. (D) To spend his vacation.

[Q]: Article: I've lived my whole life in Spanish Harlem with my mom, and I never have a father. I have friends who ended up in jail or pregnancy. But Mr.Clark wouldn't let that happen. Mr. Clark worked long hours, making sure I did my work. My grades rose. In fact ,our whole fifth-grade class's scores rose in math and reading. In sixth grade, I entered the gifted program, and Mr. Clark was the teacher. I felt so lucky to have him for a second year ! None of us were surprised when Mr.Clark was selected as Disney's 2004 Teacher of the Year. When he learned he'd won, he said he would draw three names out of a hat; those students would go with him toprefix = st1 /Los Angelesto get the award. But when it came time to draw names, Mr. Clark said, " You're all going." He got donations to fly all 37of us out to Disneyland inCaliforniaand put us at the Hilton. We were there for three days. People were amazed, but Mr. Clark really cared about us. There's no way I can imagine most teachers doing that. No way. But he saw something in us that nobody else saw. On graduation day ,there were a lot of tears. We didn't want his class to end. In 2005,he moved toAtlanta, but we always kept in touch. He started giving speeches about education and wrote a best-selling book based on his classroom rules. In 2007,Mr.Clark took some of us on a trip toSouth Africato deliver school supplies and visit orphanages. It was the most amazing experience of my life. It's now my dream to start a group of women's clubs one day, helping people from all backgrounds. I'm about to become a senior atHarlemRenaissanceHigh School. My grades are beautiful now, and I'm hoping to go to law school eventually. This fall, Mr.Clark will be opening the Ron Clark Academy inAtlanta, a school for kids who have potential but aren't reaching it, kids who are like I was -- until Mr.Clark came along.
Question: Which of the following is the best title for the passage?
Options: (A) How I Improved My Grades (B) Trips with My Teacher (C) Lucky to Have Him (D) My High School Years
[A]: C

[Q]: Article: Scientists have long understood the key role that oceans play in regulating the Earth's climate. Oceans cover 70 percent of the globe and store a thousand times more heat than the atmosphere does. What's newer is the understanding of how this key component of our climate system responds to global warming. A brake on global warming -- for now One of oceans'most important climate functions is absorbing heat and carbon dioxide (CO2), one of the gases that cause global warming. Acting as a heat sponge , oceans have absorbed huge amounts of heat and CO2in the last forty years. Fujita explains that "oceans are saving us from faster climate change -- they are a big flywheel that delays rapid overheating of the Earth, putting a brake on the climate system." "That's the good news," he adds. "The bad news is that oceans only slow the atmospheric warming. Once oceans come to balance with a greenhouse gas warmed earth, the extreme heat will remain in the atmosphere and things will get much hotter." But where and how oceans release this accumulated heat is uncertain. And as oceans store heat, fragile underwater ecosystems are struggling. The most recent scientific report from the Intergovernmental Panel on Climate Change (IPCC) also notes with concern that oceans are acidifying because of increased absorption of atmospheric CO2, and thus causing a threat for shell-forming species. Sharp increases in carbon dioxide levels will cause further acidification of oceans. Currents distributing heat Another important role oceans play is that of distributor. Oceans deliver heat and life-sustaining nutrients around the globe. Just as blood vessels bring oxygen and nutrients to cells in the human body, oceans' currents carry oxygen, nutrients and heat throughout the Earth. Oceans distribute 25 percent to 50 percent of the energy the planet receives from the sun. For example, the Gulf Stream carries heat across the Atlantic. This warm current gives northwestern Europe a milder climate than it would normally have so far north. A change to oceans' circulation patterns could throw Europe into a colder period, even as the rest of world experiences warmer temperatures.
