Example Input: (CNN) -- A federal court jury in Florida convicted seven people of participating in a global child pornography trafficking enterprise, according to the Department of Justice. Jurors convicted the seven Wednesday of multiple counts of child exploitation, pornography and obstruction of justice. Members of the organization used Internet news groups to swap and share "illegal images and videos depicting prepubescent children, including toddlers, engaged in various sexual and sadistic acts," prosecutors said. An indictment filed in the case detailed interactions between group members as they swapped and commented on images. "My thanks to you and all the others that together make this the greatest group of pedos to ever gather in one place," Freeman wrote in response to one posting, according to the indictment. And a posting from Castleman, cited in the indictment, read, "Thanks to all for the wonderful material that has been posted." An Australian constable who infiltrated the group in August 2006 was among 50 witnesses testifying at trial. He told the jury that the group traded more than 400,000 images and videos of child sexual abuse before being dismantled by law enforcement, according to the Justice Department statement. Each defendant faces a sentence of 20 years to life in prison, fines and the possibility of supervised release for the rest of their lives, authorities said. The seven will be sentenced April 14. During the six-day trial, evidence showed the seven participated in what prosecutors called a "well-organized criminal enterprise whose purpose was to proliferate child sex abuse images to its membership during a two-year period." "This was a wide-scale, high-volume, international trafficking enterprise that used sophisticated computer encryption technology and file-sharing techniques," Matthew Friedrich, acting assistant attorney general, said in the statement. The seven defendants were James Freeman of Santa Rosa Beach, Florida; Gary Lakey of Anderson, Indiana; Marvin Lambert of Indianapolis, Indiana; Neville McGarity of Medina, Texas; Warren Mumpower of Spokane, Washington; Daniel Castleman of Lubbock, Texas; and Ronald White of Burlington, North Carolina, according to the Department of Justice. <sep>Who told the jury that the group traded more than 400,000 images and videos of child sexual abuse?<sep>The Australian constable

Example Input: Speed is an important aspect of motion. It is a measure of how fast or slow something moves. To determine speed you must know two things. First, you must know how far something travels. Second, you need to know how long it takes to travel that far. Speed can be calculated using this formula: speed = distance time A familiar example is the speed of a car. In the U.S., this is usually expressed in miles per hour. Think about a trip you and your family made in the car. Maybe the trip covered 120 miles and it took 3 hours. What was the cars speed? speed = 120 mi = 40 mi/h 3h The speed of a car may also be expressed in kilometers per hour (km/h). The SI unit for speed is meters per second (m/s). This is the unit of measure a scientist would use. <sep>How is speed calculated?<sep>Speed = time motion

Example Input: My parents, Kelly and Kelley, said that it was that time of year to take a family vacation. We've been to big ride parks that have hotels with large pools. This year my parents wanted to do something different. They wanted to take us all to Elk River Castle. After lots of planning we hit the road for our trip. My Brother Kelsey and I enjoyed the long car ride there. Once we arrive, the castle looked much bigger than we had imagined. There was so much to see and so much to do. There was a swimming pool, movie theater and an elevator to take us from floor to floor. What a magical place! I was so excited because we had the whole place to our family! We spent our vacation playing around the huge castle and finding small mysterious places. There was even a tiny room in the back of one of the closets. My brother, Kelsey, and I played hide and go seek for hours, watched movies and swam until the sun went down. It was sad when our vacation finally came to an end but we made some amazing memories. We'll never forget our trip to Elk River Castle! <sep>Whose idea was it to go to Elk River Castle?<sep>The narrator's
