Problem: 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.

Question: "What are the parts of the organ where most nutrient absorption takes place?"

Answer: "Esophagus"
Answer: no

Problem: LONDON, England (CNN) -- The most eagerly anticipated animated film this year hits big screens this weekend, as "The Simpsons Movie" opens worldwide. The Screening Room spoke to creator Matt Groening and writer Al Jean in London about everyone's favorite two-dimensional yellow family. Simpsons supremo Matt Groening with his creations at the film's premiere in Springfield, Vermont Matt Groening told the Screening Room that fans had driven the demand for the movie. "We've had fans clamoring for a movie for the past 18 years," he said. The film has taken four years to come to fruition, as writer Al Jean explained. "What really held us up for a long time was to have enough people to do the show and the movie," he said. "We talked for a while about doing the movie after the show is done, but the show is never done! So it really started in earnest in 2003, when we started working on this story that became the movie." Technology has also played its part. Jean continued, "The technology to do this film really wasn't even around five years ago. For example, there was this joke I once pitched and David Silverman, the director, started drawing and as I was pitching it, it went into the film and it was cut a day later. To go from pitch to cut in two days is pretty impressive." Its creators hope that "The Simpsons Movie" will both satisfy long-term fans and bring Homer and Marge's family to a new audience. Groening told the Screening Room, "This movie is designed to both honor the people who have loved the show all this time, so there's lots of little details for them in the movie, little characters and stuff who they know and love, but we also want people who don't know the family to not be completely confused. It is a complete movie experience, but again, we have a lot of little details that only the really, true die-hard fans are going to get." And fans can expect to be entertained by plenty of cartoon mishaps. Groening said, "When you see somebody fall off the roof in a live-action film, it's funny -- we all love it. But it's not as funny as when Homer falls off the roof.

Question: "Who was quoted saying, "We've had fans clamoring for a movie for the past 18 years."?"

Answer: "Oprah"
Answer: no

Problem: Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition.

Question: "How long might it take for water to dissolve a rock?"

Answer: "Few days"
Answer:
no
