Input: As food is pushed along, it undergoes digestion. Digestion is the process of breaking down food into nutrients. There are two types of digestion: mechanical digestion and chemical digestion. Mechanical digestion occurs when large chunks are turned into smaller chucks. Perhaps not surprisingly, this happens when you chew your food. Once you swallow the food, your stomach also does some of this work. Chemical digestion occurs when food is broken down into useful nutrients. This is a chemical process that begins as you start to chew your food. The saliva in your mouth starts this process. Once you swallow, the acid in your stomach further breaks down food. From the stomach, the foods moves into the small intestine. In the small intestines, another set of chemicals goes to work. Are you surprised? Your small intestine, and not your stomach, does most of the work!

Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.
"What is friction?" is "The force that holds things to earth"?

Input: Nine families displaced by a fire at Alamo Hills Apartments in March filed lawsuits Wednesday against the apartment complex. They allege that the complex could have done more to protect belongings they were forced to abandon in the aftermath of the blaze. Bernard Dempsey Jr., an attorney with Western Michigan Legal Services, the group that represents the tenants, said Alamo Hills gave the displaced families very limited opportunity to remove belongings. "They were given three days to get their stuff out, and if they couldn't get moved out in three days, their stuff was discarded," Dempsey said. "Alamo Hills just threw it out." Others, he said, lost possessions to looters after the March 23 blaze, which left 78 people temporarily homeless. According to the lawsuit, the tenants were prohibited from entering their apartments to retrieve possessions and were promised that the complex would provide security. A spokesperson for PM One, the company that manages Alamo Hills, could not be reached for comment. Nine separate suits were filed in 8th District Court, which handles civil claims of less than $25,000. "We're asking for the reimbursement of the value of their property and a small amount for stress -- $3,000 on top of their out-of-pocket expenses for their lost stuff," Dempsey said. "They're not looking to get rich off this. A lot of this is simply because they were treated so badly." Dempsey said most of the tenants who filed suits still live at the apartment complex, although many are trying to find homes elsewhere. "The new apartments (they were provided) were not in very good shape. That's actually one of the claims," he said.
"What did nine families claim Alamo Hills Apartments failed to protect?" is "Their belongings"?
