Input: (CNN) -- Jo-Wilfried Tsonga ended Roger Federer's hopes of winning a record-equaling seventh Wimbledon title on Wednesday as the French 12th seed staged a stunning fightback to reach the semifinals. Federer appeared to be cruising into the last four after winning the first two sets, but Tsonga inflicted the Swiss world No. 3's first defeat from that vantage point in 179 grand slam matches. It was only the third time in the 29-year-old's glittering career that the 16-time grand slam champion had surrendered a two-set lead. Tsonga, ranked 19th in the world, triumphed 3-6 6-7 (3-7) 6-4 6-4 6-4 on Centre Court, serving out to love as he earned a clash with second seed Novak Djokovic. The Serbian, who beat Tsonga in the 2008 Australian Open final, ended the dream run of Australian 18-year-old Bernard Tomic. Tsonga defeated Federer for just the second time in six meetings, their first on grass. "It was amazing. I played unbelievable. It's never easy to come back against Roger. I'm so happy, it's crazy," the 26-year-old told reporters after reaching the semifinals at Wimbledon for the first time. "He's the biggest champion in the sport. He has achieved so much and is the best player in the world. To be two sets down and come back was unbelievable. I served really well. Against Djokovic I will have to come out and do the same again." Federer has now lost in the quarterfinals two years in a row, being beaten by eventual runner-up Tomas Berdych in 2010. "Jo played great. Really from start to finish I don't remember seeing a break point after I broke him in the first game," Federer said.

Input: "The impact of her interest and work on the provision of legal services in the state of California is immeasurable," said Patricia Philips, senior of-counsel for Los Angeles' Morrison & Foerster. "Its value is felt every day by someone who would otherwise be floundering around in the legal system yet dealing with very serious problems." Zelon's public-interest work has not gone unnoticed. Several organizations that share her commitment to public service - including the National Legal Aid & Defender Association and the State Bar of California - have honored her. Two years ago, Zelon received the Laurie D. Zelon Pro Bono Award, which had been named for her one year earlier by the Law Firm Pro Bono Project, which she'd helped found. "I didn't find out until I was standing in the great hall of the Supreme Court, surrounded by 300 people who were there, that the award had been named for me and was thereafter going to be given in my name. It's very hard to believe, for anyone who knows me well, but I was actually speechless for a period," Zelon said. Zelon faced one of the greatest challenges of her legal career, she said, when her appointment to the bench forced her to switch gears from civil litigation to criminal law. "It was a steep learning curve for me," she said. "It's a whole different set of processes. The rules are different. The case law is a whole body unto itself." Attorneys praise Zelon for her thorough understanding of the law. "She's extremely well-versed in the law," Leon said. "She's very thorough in her research," Wong said. Of course, not all attorneys concur with every decision Zelon makes in court. Some city attorneys disagree with her interpretation of evidentiary statutes when Zelon puts limits on their use of hearsay testimony. But lawyers who have appeared before her say that they appreciate her intelligent interpretation of the law.

Input: The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste.

Does the response "Water is absorbed and food is eliminated as waste" correctly answer the question "What happens to the food and water in the large intestine?"?
