In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. Once you create a question you also need to provide the correct answer for it. Write your answer like "Question: your question, Answer: your answer". The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Short answers containing words that are present in the passage are preferred. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is a factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.

In 2009, a race of aliens piloting giant robots have conquered Earth and forced humanity to live underground. They have done this by altering the environment, causing constant rainfall and darkness. Over 300 years later, after many generations of living underground, a small group of human rebels plan to finally take back their world from the mechanical invaders. They soon learn however that the aliens do not pilot the robots, but are the robots.A patrol, led by Lt. Blackthorn (Thomas Downey), is sent out to capture one of the robots, a Z-bot, so its operating ability can be studied. The patrol is suddenly ambushed by several robots, with some being able to reconfigure themselves, revealing different weapon systems. These units, the 'transmorphers', ambush humans by appearing as mundane features of the terrain, even fooling detection systems. The robots use "brain scans" to read the minds of humans to know their battle plans.After Blackthorn's patrol is destroyed by the machines, a female lead officer of the human resistance group, General Van Ryberg (Eliza Swenson), argues with fellow officers of the Military and Science Guilds about how to fight the war. Despite some protests, Van Ryberg decides to reinstate a disgraced soldier named Warren Mitchell (Matthew Wolf), who was court-martialed along with his right-hand man, Itchy (Griff Furst), and cryogenically frozen for insubordination. They had killed their unit officer five years earlier. Mitchell is glad to be reinstated, but learns that his former lover, Karina Nadir (Amy Weber), a fighter pilot, is now married to General Van Ryberg.Mitchell assembles a small military patrol with Itchy as his second-in-command, and Flight Commander Xandria Lux (Shaley Scott), as his military adviser. The patrol is sent out to capture a Z-bot, intact, so its fuel cells can be studied. They hope to shut the machines down by contaminating the fuel cell and placing it in a large radio tower which supposedly controls the machines.Mitchell and his group ambush and destroy a group of patrol machines, and succeed in capturing one. During the battle, Karina and another female soldier named Blair (Sarah Hall) become stuck behind enemy lines right near the radio tower. They are forced to hide in the ruins around the tower while waiting for help to arrive.Bringing the Z-bot back to their underground city, Mitchell realizes that the fuel cell has an implanted tracking device that leads the machines to the humans underground city. Van Ryberg takes over as the field commander of the human army and leads them out in a last-ditch effort to defeat the robots, and to rescue her wife.Mitchell then surprisingly learns from resident scientist Dr. Voloslov Alextzavich (Michael Tower), that he himself is an android constructed by Dr. Alextzavich, with human feelings and understandings. Mitchell realizes that he must get the Z-bot's fuel cell to the radio tower and implant it in the control computer in order to shut the robots down.Supported by an aerial strike force led by Lux, Mitchell's team fly out and make it to the radio tower where they are able to rescue Karina and Blair. The group breaks into the building, but the anti-human counter-measures make all of them sick and they cannot make it to the main control room. The situation becomes more complicated when the tower reveals itself to be a giant robot.Meanwhile, General Van Ryberg and her soldiers reach one of the terraforming stations and attempt to take it offline. They attempt to hold off a massive army of robots attacking the underground city. Lux then arrives with her fighter squadron to bomb the attacking robots.Back at the radio station, Mitchell, using his android abilities, sacrifices himself and takes the tower out, buying enough time for the rest of his team to escape. Once the tower is destroyed the robots all over the world shut down. With the battle won, Karina and Van Ryberg are reunited and the surviving humans see the sun shine through the clouds for the first time in centuries.
Question: Do the aliens pilot the robots?, Answer: No, they are the robots.

In a bohemian cafe in the low rent area of San Francisco as many artists, beat poets, and musicians hang around bus boy and waiter Walter Paisley (Dick Miller) wipes up the tables and longs to be part of the world of the bohemian arts in part because he has a crush on Carla (Barboura Morris) an artist who is friendly with the waiter. The cafe is also a place where undercover drug detectives prowl and uptown folks like to rub shoulders with the artists. Walter has no friends and spends his nights alone trying to sculpt in clay with no success until one night he accidentally kills his neighbors cat and in a demented moment of morbid inspiration he covers the cat in clay and takes it to the cafe where the beat crowd and especially Carla admire his new-found artistic verve and hail him as a new talent. Walter is beset on by his new-found public to create new real pieces and is dumbfounded as to where to start until Lou Raby (Bert Convy) tries to arrest him for possession of Heroin and Walter uses a cooking skillet to initiate a new piece that he covers in clay and takes to the cafe where his fans hail the piece as fabulous. Walter discovers that he needs to repeat his method of creativity over and again resorting to dispatching an average workman from the lumber yard, and then a young attractive model. When a showing of his art at the cafe results in the accidental uncovering of the true source of Walters art, he becomes a fugitive pursued by the artists who praised him, and he seeks refuge someplace where no one can follow.
Question: What city does the movie take place in?, Answer: San Francisco

The film is set in 2020 and begins as the Ares spacecraft enters orbit around Mars. Andre Vishniac commands an international crew of seven astronauts. They try to land, but the small landing craft crashes as a result of an altimeter error. Vishniac is immediately killed, and five other crew members are stranded inside the toppled landing craft, unable to return to the waiting Ares mothercraft. With no spare landing craft, Lowell, the pilot of the Ares, returns to Earth with it.It will take 26 months for Lowell to send a rescue ship from Earth, but the stranded landing crew have supplies for less than a year and need to find ways to extend the life support system. The main problem is the thermoelectric power generator, since air and water recycling require electrical power. Since the lander is damaged beyond repair, it no longer requires fuel, and Sagan (the mission geologist) proposes to use what is left to power an improvised silicate reactor to produce methane and water vapor from the martian soil. They try to build it, but the landing engines and propellant tanks prove to be too damaged to salvage.The landing crew tries to find ways to save electrical power, but even draconian measures will only extend the life of the generator to fourteen months. The required lifetime can be attained only if the crew is reduced to two astronauts. Sanchez, the new commander, decides that she, Sagan and Rodrigo should abandon the craft, since their specialist skills are less important to the survival of the mission. They don their spacesuits and walk to the edge of the Valles Marineris valley, not far from the crash site. Recent radar scans from the orbiter reveal a maze-like structure hidden below a thick cloud of water vapor in the Valles Marineris. The structure appears artificial and is virtually identical to another one near the martian south pole. The three astronauts try to reach the bottom of the valley before they run out of oxygen.Sagan dies of asphyxiation, but Sanchez and Rodrigo stumble upon an artificial tunnel near the bottom of the valley, containing the mummified bodies of humanoid alien beings. They find that the air pressure and oxygen content in some of the tunnels is just like that on Earth. Rodrigo dies when accidentally entering a tunnel with no atmosphere, but Sanchez manages to contact the two astronauts still at the lander, who have meanwhile discovered that they are gradually losing air pressure and have realised that there must be an air leak somewhere. Sanchez urges them to join her, as there is enough oxygen and water in the valley for them to survive until the rescue ship arrives.
Question: Why do two crew members need to leave the craft?, Answer: To extend the life of the generator.
