Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Example Input: Context: Ceraunius Tholus is a volcano on Mars located in the Tharsis quadrangle at 24.25 north latitude and 262.75 east longitude, part of the Uranius group of volcanoes.
Question: On what moon or planet can Ceraunius Tholus be found?
Example Output: mars

Example Input: Context: Earth formed at the same time as the other planets. The history of Earth is part of the history of the Solar System. Earth came together (accreted) from the cloud of dust and gas known as the solar nebula nearly 4.6 billion years ago, the same time the Sun and the rest of the solar system formed. Gravity caused small bodies of rock and metal orbiting the proto-Sun to smash together to create larger bodies. Over time, the planetoids got larger and larger until they became planets. When Earth first came together it was really hot, hot enough to melt the metal elements that it contained. Earth was so hot for three reasons: Gravitational contraction: As small bodies of rock and metal accreted, the planet grew larger and more massive. Gravity within such an enormous body squeezes the material in its interior so hard that the pressure swells. As Earths internal pressure grew, its temperature also rose. Radioactive decay: Radioactive decay releases heat, and early in the planets history there were many ra- dioactive elements with short half lives. These elements long ago decayed into stable materials, but they were responsible for the release of enormous amounts of heat in the beginning. Bombardment: Ancient impact craters found on the Moon and inner planets indicate that asteroid impacts were common in the early solar system. Earth was struck so much in its first 500 million years that the heat was intense. Very few large objects have struck the planet in the past many hundreds of millions of year. When Earth was entirely molten, gravity drew denser elements to the center and lighter elements rose to the surface. The separation of Earth into layers based on density is known as differentiation. The densest material moved to the center to create the planets dense metallic core. Materials that are intermediate in density became part of the mantle (Figure 1.1). Lighter materials accumulated at the surface of the mantle to become the earliest crust. The first crust was probably basaltic, like the oceanic crust is today. Intense heat from the early core drove rapid and vigorous mantle convection so that crust quickly recycled into the mantle. The recycling of basaltic crust was so effective that no remnants of it are found today. There is not much material to let us know about the earliest days of our planet Earth. What there is comes from three sources: (1) zircon crystals, the oldest materials found on Earth, which show that the age of the earliest crust formed at least 4.4 billion years ago; (2) meteorites that date from the beginning of the solar system, to nearly 4.6 billion years ago (Figure 1.2); and (3) lunar rocks, which represent the early days of the Earth-Moon system as far back as 4.5 billion years ago.
Question: which is not a reason why earth was molten in its early days?
Example Output: the sun

Example Input: Context: The scene opens with Ellen (Sharon Stone) riding across the prairie toward a town, when an idiot digging multiple holes looking for his gold, shoots at her. She falls off her horse and knocks him out as he checks to see if she is dead. After chaining him to his wagon, she continues into town. A large, single elimination gun fighting tournament is about to begin and she is looking for revenge on the man ( Herod/Gene Hackman) who killed her father. She arrives at the bar/hotel. Ace Hanlon shows off his deck of cards with an ace for every man he has killed. Soon, the saloon comes to life as Scars who just got out of jail, comes back to settle a score. He makes a move on Ellen, and she tells him to take a bath. Scars gets angry and kicks the blind boy's peddling wagon, as he was talking to Ellen. Later at the drafting of the tournament, the saloon owner is to sign up 16 gunfighters. Among them are The Kid (Leonardo DiCaprio), Sgt. Cantrell (Kieth David), Cort, the marksman and odds on favorite (Russell Crowe) though he was signed up against his will. Cort was an outlaw who became a preacher and built a mission. Since he was one of Herod's partners in crime, Herod now wants Cort dead. Also in the contest is Ace Hanlon ( Lance Herrickson), A Swedish Champ. and of course Herod. Anyone can challenge anyone, and each fighter must accept the first challenge. Ellen is challenged by the idiot who was digging for his lost gold. But up first was the Kid and he quickly shot the Swede and the winner is the last standing.The Swede was shot twice and then threw his gun down. Also winning, were Stg. Cantrell, Scars, and Eugene the scumbag. Herod has challenged Ace(because he thinks Ace was hired to kill him) and one of Herod's men challenged Cort. After Rusty, another of Herod's men has beaten Cort up as he was chained to a fountain in the middle of the village. Herod has Cort released so that he can go to the Kid's gun store. Herod gives Cort the cheapest gun in the place. The Kid also has told everyone that Herod was his father. Herod denies that and rubs it in the Kid's face. Then Cort went out to a fight that he refused to be in. But when the clock stuck, only one bullet was fired. Herod's man fell to the ground. Many claimed to be the fastest gun in town, like the Kid, Herod, and Ace, but all knew that Cort was the fastest. Next, Ace is bragging and doing gun tricks. It is time for he and Herod to face each other. Herod proves that Ace has been lying about all of his kills. The clock strikes and Herod blows Ace's right thumb off. Then he shoots Ace's left hand. Then after mocking Ace some more, Herod's shoots him in the chest. Then Ellen wins her first fight with Cort's help. The next day, Herod invites Stg. Cantrel to his home. He tells the Sgt, that he knows that he was the hired hand and not Ace. The Sgt. does not tell him much and the challenge has been issued. Later, Herod changes the rules and now all fights are to the death. Herod takes down Cantrell, and then scolds the crowd for hiring him. Meantime, Eugene the scum bag is heard upstairs molesting a girl. He comes downstairs and brags about it. Ellen attacks him from behind and the two scream at each other until the challenge is made. though it is pouring outside, The two come out firing and Eugene gets his manhood shot off. The rules have changed and the winner is the last alive. Ellen couldn't finish him off, so she returned to the bar. Eugene comes in and shoots her glass. Then Ellen empties her gun into him.Though Herod tells the Kid to quit, that he has proven his point, the Kid stays in and takes
