In this task, you will be shown an extract from a movie plot and a question. You need to provide the correct answer for it. Short answers containing words that are present in the passage are preferred.

The scientific team of Dr. David Conway (William Leslie), Dr. Ellis Morton (Tristram Coffin) and Laura Hutchinson (Kathryn Grant) has built a machine that can predict earthquakes. After predicting one will hit California within the next 24 hours to a uniformly skeptical Gov. Cheney (Raymond Greenleaf) and state-level political and civil defense officials, the earthquake does materialize and does immense damage to northern parts of the state. Now with the support and funding necessary from the reformed skeptics, the team works on further predictions and comes to the conclusion that a wave of earthquakes are pending in and around the southwestern United States. They trace the epicenter of the pending disaster to an area beneath the Carlsbad Caverns and descend to a hitherto unexplored level.Here they find a strange ore which, when removed from contact with water, becomes highly explosive, and realize that this element, somehow working its way from deep in the Earth, is responsible for the earthquakes. Although the material is not analyzed for specific atomic traits, it is named Element 112 just because so far, 111 chemical elements had been discovered. A computer determines that in approximately one month, enough of Element 112 will emerge from the deep earth to cause the entire planet to explode. A desperate operation ensues worldwide to blast and trench the ground to let water in and cover Element 112, keeping it from drying out and expanding., Question: In the movie, what does the machine do that Dr. David Conway and his colleagues built?
Answer: predict earthquakes

(March 2016) (Learn how and when to remove this template message)Prior to Christmas break, an unnamed female student (Emily Blunt) at a Pennsylvania university uses the campus ride share board to find a ride home to Wilmington, Delaware on 23 December. She finds a ride, which turns out to be a male student (Ashton Holmes), also unnamed ("the guy" in the credits), who is also driving to his home in Wilmington. His car is old and in poor condition, with the trunk full of his possessions (he tells her he is being kicked out of his apartment). It soon becomes apparent that she is somewhat arrogant and anti-social and his attempts to start a conversation go nowhere. It also becomes apparent that he knows quite a lot about her and possibly that he does not actually live in Wilmington as he claims. He tells her that they have a philosophy class together, although she has never noticed him.The pair stop at a rather insalubrious gas station, where the girl goes to the bathroom and is temporarily locked in when the door handle sticks and then comes off in her hand. After managing to escape, she berates her companion for not hearing her shouting for help. She becomes even more suspicious when she hears him asking the clerk for directions, although he claims he has driven the route many times. Soon after setting off again, he turns off the main highway down Route 606, a lonely snow-covered road through a wooded ravine which he claims is a short cut. She tells him to return to the main highway, but he refuses. Crosses, apparently on graves, can be seen on the slopes on either side of the road.As night falls, while approaching a bridge, the pair see headlights coming towards them in the middle of the road. The oncoming driver does not slow down, causing the guy to swerve. Their car ends up half buried in a snow drift and they are unable to budge it. The guy observes that the oncoming car, which did not stop, has left no tire tracks in the snow. A radio news report warns that an incoming storm will bring snow and temperatures down to 30 degrees below zero.The guy heads back up the road to try to reach the gas station. The girl, staying in the car, sees a muffled figure staggering down the road past the car. She follows it and calls out, but it ignores her. Soon afterwards, the guy returns, saying the gas station is closed. She does not think he has been gone long enough to get there and back. The two huddle back in the car, where the guy finally reveals that he has been watching the girl for some time and has a crush on her. He actually only lives ten minutes' drive from campus, but was sitting behind her in class and saw her texting about getting a ride share. He immediately put up the notice on the board offering a ride to Wilmington and she took the bait. He says he's not really stalking her, but just wanted to be alone with her as he likes her. She apparently believes him.They notice a number of black-clad figures walking past the car and call after them, but they do not stop. Their faces are white and dead-looking. The guy follows them up the slope into a ruined building where they disappear. He finds frozen corpses half buried in the snow inside and also a newspaper, which he brings back to the car. Meanwhile, the girl sees the staggering figure again and runs after it. She gets close enough to touch it, burning her hand, and it turns round, revealing a bloated corpse. An eel falls from its mouth and slithers away.They think help has arrived when a Pennsylvania Highway Patrol officer (Martin Donovan) knocks on their window. Oddly, he doesn't seem to understand their predicament, choosing instead to believe they were parking. Taking the girl from the car, he tries to get her into the back of his patrol car, which is clearly not a modern vehicle. When it becomes clear to her that he means her harm, she struggles to get away, but cannot. The guy appears behind the officer and hits him across the head with a tire iron. They awaken, wondering whether it was all a dream, to find that the guy has the tire iron frozen to his hands, which are frostbitten. It becomes apparent that he was badly injured in the crash, and he admits that he did not get far when he went for help before he started spitting up blood, but claimed he had got to the gas station and back in order not to worry her. The girl reads the headline on the newspaper he found in the ruined building. It is dated 23 December 1953 and tells of an accident in which a young couple and a police officer were killed when their cars crashed into a ravine on this road. Priests from a nearby home for retired Catholic priests gave them the last rites. They accept that the police officer is a ghost and the black-clad figures they have seen are the ghosts of the priests.The police officer appears again several times, always heralded by Brenda Lee's "Rockin' Around the Christmas Tree" coming onto the car radio. Other ghosts also appear. The girl drifts in and out of consciousness, becoming in her dreams people the cop has killed. She realizes that she can call for help from the junction box at the top of a nearby telephone pole, as the phone from the guy's apartment is in the car. She does so, watched by the ghosts, although luckily the cop, apparently the only malevolent spirit, does not appear. She gets through on 911, but the line is bad and she is not sure that they have received her message. Dispirited, she returns to the car, only to find that the guy has died of his injuries.Some time later, there is again a knock at the car window. Expecting it to be the ghostly cop, she instead finds that it is a snow-plow driver (Ned Bellamy), who appears to be real. He puts her into his truck and the guy's body on the back and calls in that he has found the reported accident using his radio. As they drive off, he tells her the story of the road. In the 1950s, a corrupt cop murdered people on this stretch of road and their bodies were never found. In 1953 he was drunk and ran a young couple off the road, but he also lost control and plunged into the ravine. Frequently, at around this time of year, people are found dead on this road. In 1963, the priests who had given the accident victims the last rites were found frozen to death in their beds. Then the pair see headlights approaching. The driver thinks it is more help arriving, but it is of course the ghostly police car, which runs them off the road and disappears. The truck is not stuck, but, despite the girl's pleas not to, the driver gets out to help the driver of the other car, which he assumes has gone down the ravine. The girl follows him and the pair see two burning cars down the slope. The cop is trapped in his burning car. As they watch, the priests come down the slope, but instead of helping him they pull the microphone from his radio, preventing him from calling for help. They leave again as he burns to death. His burned body crawls from the car and touches the snow plow driver, who freezes to death as the girl watches. She tries to start the truck, but the policeman appears again. The ghost of the guy also appears and once again hits him with a tire iron, saving her.As dawn rises, she awakes back in the car, with the guy's body next to her. There is no sign of the truck. The guy's ghost appears and leads her up the hill, through the ruined priests' home and finally to the gas station on the highway, where he disappears. She calls the emergency services., Question: What is the officer hit with?
Answer: A tire iron.

On August 12, 2011, large masses thought to be meteors land in the oceans near several major coastal cities. The objects are discovered to be spacecraft containing hostile extraterrestrial life. Marines from Camp Pendleton arrive in Los Angeles, including SSgt. Michael Nantz (Eckhart), an Iraq War veteran. Nantz was to begin retirement, but because of the attack, he is made the acting platoon sergeant for 1st Platoon, Echo Company, of the 2nd Battalion 5th Marines.[5]Under the command of 2ndLt William Martinez (RodrÃ­guez), the platoon arrives at Santa Monica Airport, now a Forward Operating Base. The alien ground forces have no apparent air support, so the Air Force prepares to carpet bomb the Santa Monica area, and the platoon is tasked with rescuing civilians from an LAPD police station in West Los Angeles before the bombing. As they advance through the city, they are ambushed and suffer multiple casualties, namely Grayston, Guerrero and Lenihan in the firefight. Nantz takes Imlay and Harris to look for Lenihan, who is missing from the group after having been wounded. After fighting off a hostile alien, they manage to regroup and team up with a group of Army National Guard soldiers from the 40th Infantry Division, and an Air Force intelligence TSgt, Elena Santos (Michelle Rodriguez). At the police station, the platoon finds five civilians: veterinarian Michele (Moynahan), children Hector Rincon (Cass), Kirsten (King) Amy (Gould), and Hector's father Joe (PeÃ±a). A helicopter arrives to evacuate the wounded Marines, but cannot rescue the civilians due to weight restrictions. As the helicopter takes off, it is destroyed by alien air forces, killing Grayston, Guerrero, Lenihan and Simmons.[5]The Marines commandeer a city bus for evacuation. They also vivisect a wounded alien with the help of Santos and find a vulnerable spot in its torso, as well as learning that the alien aircraft are drones that track down humans through radio transmissions. Santos reveals that her original mission was to locate the aliens' central command center, believing that its destruction would deactivate the drones. On the I-10 freeway, the bus comes under attack. Because the off-ramp is destroyed, the Marines are forced to rappel the civilians off the freeway. Marines Stavrou (Pesi) and Mottola (Liao) and the National Guard soldiers are killed, while Joe and Lieutenant Martinez are wounded. Martinez detonates explosives inside the bus, killing himself and the aliens, leaving Nantz in command. The surviving Marines Nantz, Santos, Imlay, Kerns, Lockett, Harris, Adukwu and the civilians escape the bombing zone. A news report speculates that the aliens are seeking Earth's water for fuel while attempting to colonize the planet and eradicate humans. The team prepares for the bombing, but nothing happens. Returning to the FOB, the Marines find that it is destroyed and the military is retreating from Los Angeles. The Marines plan to escort the civilians to an alternate extraction point. Joe dies from his wounds and Lockett confronts Nantz over his brother, Cpl Dwayne G. Lockett and the others who were killed in Nantz's last tour. They come to peace when Nantz explains that he thinks of them every day, and recites each person's name, rank and serial number. Nantz then says that the surviving Marines should move forward united to honor their fallen comrades, including Joe. They successfully reach the extraction point and evacuate through a helicopter.[5]In mid-air, the chopper experiences a brief loss of power. Nantz theorizes that they are hovering over a location occupied by the alien command center as it relays radio energy to its drones. He decides to recon the area alone, but his team insists on accompanying him. Searching underground, the Marines confirm the presence of a large alien vessel. Kerns radios in to request for missiles, which Nantz manually directs using a laser designator while the others defend his position. Despite Kerns being killed when a Drone spots his signals, the Marines succeed in routing a missile to the command module, which is destroyed. The alien ground forces retreat as their uncontrolled drones crash, just as reinforcements for the Marines arrive. At a Temporary Operating Base in the Mojave Desert, Nantz, Imlay, Lockett, Harris, and Adukwu, the six survivors of the original platoon along with Santos, are greeted as heroes. Despite orders to rest, they re- arm themselves and join the rest of the Marines in retaking Los Angeles as other countries wage similar military operations against the hostile species.[5], Question: what does the news report speculates?

Answer: that the aliens are seeking Earth's water for fuel
