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.

Example Input: A mid-1950s construction worker involved in the demolition of the "J. C. Wilber Building" finds a box inside a cornerstone. He opens it to find a commemorative document dated April 16, 1892. Inside is also a singing, dancing frog, complete with top hat and cane. After the frog suddenly performs a musical number there on the spot, the man tries exploiting the frog's talents for money. However, the frog refuses to perform for any individual other than its owner, instead devolving into croaking in the presence of others. The man frantically tries to demonstrate the frog's abilities to the outside world, first by trying to get a talent agent to accept him, then by renting out a theater for it to perform in, all to no avail.After these failed attempts to profit from the frog, the man becomes destitute and is living on a park bench, where the frog still performs only for him. A policeman overhears this and approaches the man for disturbing the peace, but when the man points out the frog as having done the singing, the officer takes the man into custody. He is committed to a psychiatric hospital along with the frog, who continues serenading the hapless patient. Following his release, the haggard, broken man, carrying the frog inside the box, spies the construction site where he originally found the box, and dumps it into the cornerstone of the future "Tregoweth Brown Building" before sneaking away. The timeline then jumps to 2056 (101 years after the cartoon's debut). The Brown Building is being demolished using futuristic ray guns, and the box with the frog is discovered yet again by a 21st-century demolition man, who, after envisioning riches as well, absconds with the frog to start the process once again., Question: What two things does the construction worker find inside the box from the cornerstone of the demolished J.C. Wilber building?
Example Output: Answer: A document and a frog

Example Input: The plot focuses on a field trip by Professor Ernst Prell to investigate Yeti sightings, along with four graduate students: Keith Henshaw, Karen Hunter, Tom Nash and Lynn Kelly.The night before the trip, the professor invites Keith to dinner at a restaurant, where he samples an exotic dish named "gin sung." The rest of Dr. Prell's students attend an off-campus party where they encounter a former student, turned alcoholic groundskeeper, named Spencer St. Clair, who is there with his wife April. St. Clair proceeds to tell everyone within earshot the story of Prell's last Yeti-seeking field trip, which only he and the professor survived.After the party, Spencer continues to drink, and upon returning home fights with his wife and cuts her throat with an electric carving knife. Afterwards, he climbs into the bathtub fully clothed. He is killed by his not quite dead wife, who drags a toaster into the bathroom and dumps it into the bath, electrocuting him.In the morning, the professor travels by van with his students to Boot Island, where his friend Dr. Karl Werner lives. Werner has recently seen the Yeti on his island, and conjectures that he was marooned there by melting winter ice. He introduces the others to a mute Native American manservant named Laughing Crow. The group have dinner, which is again "gin sung," then go to sleep after one of the students, Tom, sings a song about the Yeti.The next day, the professor and his students begin their search in the woods of the island. Tom sneaks off to go hunting and is killed by the Yeti, a shaggy creature whose loud heartbeat is clearly audible. The rest of the group look for Tom the next morning. Karen finds only his rifle and his severed leg. Meanwhile, Lynn goes into Dr. Werner's greenhouse and sees something that frightens her; she runs into the woods and is also killed by the Yeti.At the house, the remaining students find that the phone is out of order. The professor decides to use Tom's leg as bait to lure the Yeti into a trap. The plan fails, however, as Prell returns to the house claiming he was knocked down by the monster, who escapes with the leg in its jaws. Prell then decides to try again, using Lynn's body as bait. Karen tries to hide the body in the greenhouse, where she discovers the rest of Tom's body, and passes out. When she awakes, Dr. Prell tells her it must have been a dream as she was asleep for quite some time. Karen doesn't believe him leading them all back to the greenhouse where they uncover Lynn's body. "I guess this proves its not Tom," Prell said.Disgusted that Dr. Prell is going to use their friends body as bait, Karen reluctantly agrees to help out by taking photos, under the condition that they leave Boot Island if they succeed or fail. Both Dr. Prell and Keith agree. Karl wishes them good luck.The professor ties Lynn's body to a tree and the trap is set. The Yeti appears and Keith chases it into the woods. He tracks it by the sound of its heartbeat, but makes the discovery that the sound is actually coming from a speaker attached to a tree. Someone knocks him out with a branch.Back at the house, Laughing Crow is shown listening to an LP record of the Yeti's heartbeat. It turns out that Dr. Prell and Werner are cannibals, using the Yeti scam as a way to lure victims, and that the Yeti is actually Dr. Werner in disguise. While Karen is asleep upstairs, Keith returns to the house and discovers Dr. Prell and Dr. Werner discussing what to do with her. Werner thinks they should just kill her, but Prell says that the code calls for no body bruises and that she must be frightened to death. Keith pulls out a rifle and orders both men to put their hands up. They ignore him. He shoots at them, finding out that the shells are blanks. He is then knocked unconscious by Laughing Crow. Still asleep upstairs, Karen wakes to a growling noise. She looks out the window and finds the Yeti running full speed at the house. Karen flees through the house and ends up trapped in a bathroom. She opens a cabinet to find Laughing Crow holding a knife, and dies of fear. While setting up for their big breakfast, Keith wakes up and manages to sneak away. He tries to escape in the van,but it gets stuck in the mud while trying to hide from the party guests funeral procession. Keith then hoofs it down to the bridge where he manages to flag down a cop who takes him back to the house. At the breakfast, Prell and Werner salute the party guests and hosts, toasting the previous schemes which have provided victims. Keith returns with a local policeman, only to find out that he too is a cannibal. Prell and Werener explain that the "gin sung" Keith has eaten is actually human flesh, and they invite him to join their cannibalistic society. They bring in Karen's body, and Laughing Crow, brandishing an electric carving knife, speaks for the first time, saying "Mr. Henshaw white meat or dark?" Keith drools. The film ends., Question: When Keith tries to escape, what happens to his escape vehicle?
Example Output: Answer: It gets stuck in the mud.

Example Input: The rocketship MR-1 (for "Mars Rocket 1"), returns to Earth after the first manned flight to Mars. At first thought to have been lost in space, the rocket reappears but mission control cannot raise the crew by radio. The ground crew land the rocket successfully by remote control. Two survivors are found aboard: Dr. Iris Ryan (Naura Hayden) and Col. Tom O'Bannion (Gerald Mohr), the latter's arm covered by a strange alien growth. The mission report is recounted by Dr. Ryan as she attempts to find a cure for Col. O'Bannion's arm.While exploring Mars, Ryan is attacked by a carnivorous plant, which is killed using a freeze ray (nicknamed "Cleo") fired by Chief Warrant Officer Sam Jacobs. They also discover an immense bat-rat-spider creature, after mistaking its legs for trees, and the monster is repelled, again by Jacobs. When they return to their ship, the crew find that their radio signals are being blocked and the MR-1 is grounded by a force field. O'Bannion leads the crew to a Martian lake with a city visible on the other side. They cross in an inflatable raft, only to be stopped by a giant amoeba-like creature with a single spinning eye. The creature kills Jacobs and infects O'Bannon's arm. The survivors escape to the MR-1 and commence liftoff. Prof. Theodore Gettell, the ship's designer, dies of an apparent heart attack due to the stress of the lift-off from Mars. The survivors then return to Earth, where O'Bannon's infected arm is cured using electric shocks.When the mission scientists attempt to examine the expedition's data recorders, all they find is a recorded message. An alien voice announces that the MR-1 crew were allowed to leave so they can deliver this message to Earth. The Martians have been watching human development throughout history, believe our technology has outpaced cultural advancement, and accuse mankind of invading their world. They warn humanity to never return to Mars or Earth will be destroyed in retaliation., Question: what announces that the MR-1 crew were allowed to leave so they can deliver this message to Earth?
Example Output:
Answer: An alien voice
