question:
So what is gravity? A typical definition of gravity is that it is a force. It causes an attraction between two masses. According to this definition, anything that has mass exerts a force. Any object exerts gravity on other objects. It does not matter how small it is, it has gravity. The more matter an object has, the more gravity it has. Your pencil has a tiny bit of gravity, but far too little to notice. What about a planet? It would have a lot of gravity. An objects gravity exerts a pull on other objects. Friction only occurs between objects that are touching. Gravity can act between objects that are not touching. In fact, gravity can act over very long distances. Where else can you feel gravity? <sep>How do objects interact under gravity?<sep>gravity causes an attraction between two masses
answer:
Yes


question:
Hurlburt Field, Florida (CNN) -- An Air Force CV-22 Osprey crashed Wednesday during a routine training mission north of Navarre, Florida, injuring five crew members aboard, a military official said. The crash occurred about 6:45 p.m. at Hurlburt Field's Eglin Range, said Amy Nicholson, chief of public affairs at the airfield. The five injured crew members were taken to an area hospital, Nicholson said. The extent of their injuries was not immediately known. The cause of the accident is under investigation, she said. The Osprey was assigned to the 1st Special Operations Wing, the Air Force said. The tilt-rotor aircraft can fly like an airplane and land like a helicopter. The Army began developing the Osprey in 1982, though the program was nearly scrapped in 1989 when then-Secretary of Defense Dick Cheney sought to cancel it because of ballooning costs. Questions were raised about the safety of the Osprey after two crashes, including one in 1992 at a Marine Corps air base in Virginia that killed the crew. In late 2000, the Marine Corps grounded the Osprey fleet after two crashes -- one in Arizona that killed four crew members and 15 passengers, and another in North Carolina that killed the crew. A redesign was ordered on the Osprey, and it resumed flights in 2002. The Air Force began using Ospreys in 2008 after testing the aircraft in 2006. They were first deployed by the Marines in Iraq in 2007 after 18 years and $20 billion in development. <sep>How many people have died from the crash in Navarre, FL and in Arizona combined?<sep>19
answer:
Yes


question:
Littlefoot 's grandfather one night tells the children a story about `` The Lone Dinosaur '' , a legendary longneck who once protected the Great Valley from the most ferocious sharptooth ever to live . A fight ensued , which led to the Sharptooth 's death . However , the sharptooth left `` The Lone Dinosaur '' with a scar slashed across his right eye . Soon after the battle , a huge monolith that resembled a proud sauropod , having life-sized Sharptooth teeth arranged around his neck , came out of the ground during an earthquake . The dinosaurs called it `` Saurus Rock '' . The legend also states that if anyone damages the monolith , bad luck would descend upon the valley . A few days later when the kids are playing , Littlefoot accidentally falls off a cliff . Just before he hits the ground , a gruff Diplodocus rescues him . This longneck introduces himself only as `` Doc '' and gives no knowledge of his history . Littlefoot is intrigued by this newcomer , who is scarred across one eye and displays prior knowledge of the Great Valley 's topography . For the preceding reasons , Littlefoot assumes that Doc is the Lone Dinosaur . He tells his friends this , narrating an apparently extemporaneous legend to support his assumption . Inspired , Cera 's infant nieces , the twins Dinah and Dana , go to Saurus Rock without anyone noticing . Later when the friends are playing , they notice that Dinah and Dana are missing . Recalling their talk of the day before , they go to Saurus Rock to find them . <sep>Where Dinah and Dana go when they heard the story of The lone Dinosaur from Littlefoot?<sep>Friends

No
