Question: Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it. <sep>The force magnets put on certain materials is called what?<sep>Magnets do not put force on certain materials

Answer: No


Question: In Colombia, the drug-financed guerrillas trying to seize the country and destroy democracy include M-19, which Castro has clearly backed. Robert Merkel, a former U.S. attorney handling drug indictments in Florida, doesn't think for a minute that Castro's much publicized trials of high officials engaged in the drug trade mean he has broken off with the Medellin drug cartel. "If the cartel succeeds in blackmailing the Colombian authorities into negotiations, the cartel will be in control and Fidel can exploit his past relationships with them," he told the Journal's David Asman recently. The struggle against the drug lords in Colombia will be a near thing. This week, the government arrested Jose Abello Silva, said to be the fourth-ranking cartel leader. He will probably be extradited to the U.S. for trial under an extradition treaty President Virgilia Barco has revived. Later, another high-ranking trafficker, Leonidas Vargas, was arrested and 1,000 pounds of dynamite seized. Mr. Barco has refused U.S. troops or advisers but has accepted U.S. military aid. President Bush has agreed to meet within 90 days with Mr. Barco, President Alan Garcia of Peru and President Jaime Paz Zamora of Bolivia to discuss the drug problem. It might not be a bad idea to do that sooner, rather than later. After the Panama fiasco, they will need some reassurance. Certainly, the Colombian press is much in need of that. <sep>Who is going to be extradited to the U.S?<sep>Alan Garcia

Answer: No


Question: (CNN) -- Shain Gandee, one of the stars of the MTV reality show "Buckwild," has been found dead along with two other people in Kanawha County, West Virginia, authorities said Monday. "This is a very sad and tragic event," Kanawha County Commissioner Kent Carper said. "We live in a very small community. Our thoughts and prayers are with the Gandee family." Gandee, 21, was found dead in a vehicle along with his uncle, David Dwight Gandee, 48, and Donald Robert Myers, 27, authorities said. 'Buckwild' producer talks about the show "Earlier this day after releasing information Shain Gandee was missing, the Kanawha County Sheriff's Office received word of a disabled vehicle in a wooded area near Thaxton Hollow, Sissonville, Kanawha County WV," said a statement from the Sheriff's Office. "Deputies and members of the Sissonville Volunteer Fire Department used all terrain vehicles to access that vehicle, a 1984 Ford Bronco belonging to the Gandee family. The vehicle was in a muddy area along a worn path. Inside were the bodies of three people." In a subsequent release, the Sheriff's Office said the vehicle was partially submerged in mud. It was uneven but upright; its muffler was below the surface. Mud covered the lower part of the Bronco's passenger side door, but the driver's side, where the younger Gandee sat, was free, the Sheriff's Office said. Gandee was happy with life before death He was one of the nine cast members of "Buckwild." The show follows a group of young adults trying to have fun in Sissonville, West Virginia, pulling stunts such as turning a dump truck into a swimming pool or just riding around the woods on their all-terrain vehicles. Gandee was billed as a former high school prom king who had done "every job from coal mining to being a garbage man." <sep>How many days was Shain Gandee missing before his death?<sep>It happened the same day
