[Q]: Generate a question that has the following answer: monocle for the following movie plot: In 1942, both Nazi Germany and the Soviet Union are gathering forces and supplies in one particular sector of the Eastern Front for a major attack. The Soviets are secretly constructing a bridge at night over a river. To avoid detection, it is being built underwater, just below the surface. In an attempt to find out where the Germans plan to strike, Colonel Semenov (George Macready) has a small paratrooper unit dropped behind enemy lines to attack a divisional headquarters and hopefully take an officer prisoner for interrogation. The local partisans, led by the wily Kostyuk (Roman Bohnen), provide a guide, Lisa Elenko (Marguerite Chapman). The attack succeeds at first. Alexei Kulkov (Paul Muni), one of the paratroopers, takes seven Germans prisoner in the basement. Then, just as Elenko brings him a message, German artillery hits the building, causing it to collapse and trap them in the spacious cellar. Afterward, Kulkov's dog sniffs out where his master is buried and starts digging. This alerts one of Kulkov's comrades, who communicates with him by tapping on a metal pipe in code. Learning that Kulkov has caught an officer, he leaves to get help. Kulkov is in no hurry to dig out. Though the prisoners rank no higher than a sergeant, he is convinced one of them is an officer in disguise, based on a pistol and a monocle he has found. He begins questioning the men one by one, but while he rules out ex-miner Stillman (Rudolph Anders) and a former magician (Philip Van Zandt), he cannot pinpoint his man. An eighth German soldier, thought to be dead, wakes up and attacks. In the struggle, the lone lantern is extinguished and Elenko is stabbed in the shoulder. However, Kulkov kills him and regains control of the situation. Oddly, Elenko is certain that one of the Germans tried to help her in the darkness. Kulkov decides to try a ploy. He orders the magician to go around the corner of the main room out of sight of the others. He knocks the German out and then fires one round, making the rest think he has exacted...

[Q]: Generate a question that has the following answer: American for the following movie plot: An alien spacecraft is discovered on the floor of the Pacific Ocean, estimated to have been there for 300 years (288). A team of experts, including marine biologist Dr. Beth Halperin, mathematician Dr. Harry Adams, astrophysicist Dr. Ted Fielding, psychologist Dr. Norman Goodman, and U.S. Navy Capt. Harold Barnes, are assembled and taken to the Habitat, a state-of-the-art living environment located near the spacecraft. On examination of the spacecraft, they determine that it is not alien at all, but rather American in origin. However, its technology far surpasses any in the present day. The ship computer's logs cryptically suggest either a mission originating in the distant past or future, but the team manages to deduce that the long dead crew were tasked with collecting an item of scientific import. Goodman and the others eventually stumble upon a large, perfectly spherical ball of fluid hovering a few feet above the floor in the ship's cargo bay. They cannot find any way to probe the inside of the sphere, and the surface is impenetrable; the crew finds it odd that the surface of the sphere reflects its surroundings except for humans. They return to the Habitat, and Harry comes to believe that everyone on this team is fated to die. His rationale is that if they survive, their reports will be known by the spacecraft's crew on their future mission, and the crew will be able to foresee and avoid the black hole, thus avoiding the "unknown event," referenced in the logs, and not ending up where Harry's team has found it. During the night, Harry returns to the spacecraft and is able to enter the sphere, then returns to the Habitat. The next day, the crew discovers a series of numeric-encoded messages appearing on the computer screens; the crew is able to decipher them and come to believe they are speaking to "Jerry", an alien intelligence from the sphere. They find Jerry is able to see and hear everything that happens on the Habitat. A powerful typhoon strikes the surface, and the Habitat crew are forced to stay...
