Task: Question Generation
Input (English): The film opens with newspaper photojournalist Audrey Aimes (Castle) accidentally stumbling upon a small town in Illinois which has been inexplicably destroyed. All 150 people in the town are missing, and the evidence indicates they are dead. Incredibly, the local fields are also barren, as if a swarm of locusts had eaten all the crops. Aimes suspects that the military is covering something up, and travels to a nearby United States Department of Agriculture experimental farm to learn what creature might have caused the agricultural destruction. She meets Dr. Ed Wainwright (Graves), who is experimenting with radiation as a means of growing gigantic fruits and vegetables to end world hunger. Dr. Wainwright reports that there have been a number of mysterious incidents nearby, and that locusts have eaten all the radioactive wheat stored in a nearby grain silo.Gigantic mutant locusts rampage over the countryside. Dr. Wainwright and Ms. Aimes begin to track down the source of the mysterious occurrences, and quickly discover that the locusts which ate the grain have grown to the size of a city bus. The monsters have eaten all the crops in the area, and now are seeking human beings as a means of sustenance. It is also clear that they are headed for the city of Chicago. Wainwright and Aimes meet with General Hanson (Ankrum), Colonel Sturgeon (Henry), and Captain Barton (Seay) to strategize a solution. Machine gun and artillery fire seem ineffective against the creatures, and there are far too many to effectively deal with all at once. The United States Army and Illinois National Guard are called upon to help protect the city. But the monsters quickly invade Chicago, and began to feast on human flesh as well as several buildings.General Hanson concludes that the only way to destroy the beasts en masse is to use a nuclear weapon and destroy Chicago. However, Dr. Wainwright realizes that the locusts are warm-weather creatures. He concludes that he might be able to lure the locusts into Lake Michigan. There, the cold water will incapacitate them, and they will drown. The lure itself will be a decoy locust mating call, generated electronically with test-tone oscillators. The plan is put into effect, and it works at the last possible moment. The monstrous locusts drown, but Dr. Wainwright and Ms. Aimes wonder if other insects or animals might have eaten other radioactive crops. They ponder whether the whole world might be facing an attack of monstrous creatures.
Output (English): Question: The decoy mating call is generated electronically with what?, Answer: test-tone oscillators
