Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Example Input: The movie begins in the year 1967 with a pregnant woman being admitted to a hospital, bleeding from the neck. Paramedics think she was attacked by some type of animal. Doctors perform an emergency C-Section, and her baby (a boy) is born alive just as she dies.Thirty years later a young man named Dennis (Kenny Johnson) is riding in a car with an attractive redhead named Racquel (Traci Lords) heading to an underground nightclub (located, oddly, in a slaughterhouse) somewhere in Los Angeles. After addressing the doorman in Russian, Racquel brings the young man into the club. The man is confused and trying to understand the rules of the club. Some of the regulars indifferently push him aside. Saying he needs a drink, the sprinkler suddenly system activates, raining blood down on everyone inside. It is then that he (and the audience) realizes that everyone in the club is a vampire.Dennis desperately tries to get away and winds up at the feet of a menacing figure in a black-leather trenchcoat. The vampires look on this figure with awe, mumbling the words: "it's the Daywalker!" This is our first look at Blade (Wesley Snipes), the vampire killer.Blade pulls out a shotgun and opens fire on the vampires, who instantly burn to ashes when killed. When the gun is knocked out of his hands by Racquel, Blade uses a set of silver stakes to kill Racquel and more vampires, including the disk jockey. Soon all the vamps are either dead or have fled except for one; a heavyset vamp named Quinn (Donal Logue), whom Blade has apparently run into before. Blade pins Quinn to the wall, and then sets him on fire before confronting the last member in the club (the human man from the beginning). Finding no vampire bite marks on Dennis, Blade lets him live and makes his escape as the police arrive.Quinn is extinguished and taken to the local hospital. A morgue technician examines his blood and shows the results to Dr. Karen Jenson (N'Bushe Wright), who finds a number of irregularities, including abnormally developed jaw muscles. As they are discussing the test results, Quinn springs back to life and bites both doctors. Before he can finish Dr. Jenson, Blade shows up and saves her, cutting off one of Quinn's arms.Blade brings Karen to his hideout and asks for help from his mentor, an elderly man named named Whistler (Kris Kristofferson). Whistler injects Dr. Jenson with a solution of garlic essence and silver nitrate and remarks that she has a 50/50 chance of recovering.Meanwhile, a group of vampires are discussing Blade's latest attack on their members. Apparently this club (and to an extent, Quinn) is the property of a vampire named Deacon Frost (Stephen Dorff). Frost wants the vampires to outright rule the humans and use them as a food source while the others (particularly an older vampire named Dragonetti) prefer to maintain a peaceful co-existance. Dragonetti (Udo Kier) in particular does not like Frost because Frost is not a "pure-blood" (ie: was not born a vampire, merely became one through the bite of another). Frost is also arrogant and his & the actions of his followers draw unnecessary attention to the vampire underworld.The next morning, Jenson awakens and sees Whistler injecting Blade with some type of serum. She tries to run away but Whistler confronts her and tells her that he and Blade are hunting vampires. Karen of course is skeptical, but Whistler goes on to talk about what they use to hunt- explaining that vampires are severely allergic to silver & garlic while also being vulnerable to sunlight (ultraviolet rays in particular). Whistler fuels up Blade's car and gives him a new UV flashlight to use when hunting that night. Whistler also gives Karen a type of "vampire mace" (garlic & silver nitrate in a liquid form).Blade drops Karen off at her apartment and she tries to pack up and get out of town. A police officer, identifying himself as Officer Krieger (Kevin Patrick Walls), arrives and questions her about the events
Example Output: What are the weapons made out of?

Example Input: Topographic maps represent the locations of geographical features, such as hills and valleys. Topographic maps use contour lines to show different elevations. A contour line is a line of equal elevation. If you walk along a contour line you will not go uphill or downhill. Topographic maps are also called contour maps. The rules of topographic maps are: Each line connects all points of a specific elevation. Contour lines never cross since a single point can only have one elevation. Every fifth contour line is bolded and labeled. Adjacent contour lines are separated by a constant difference in elevation (such as 20 ft or 100 ft). The difference in elevation is the contour interval, which is indicated in the map legend. Scales indicate horizontal distance and are also found on the map legend. Old Faithful erupting, Yellowstone Na- tional Park. While the Figure 1.1 isnt exactly the same view as the map at the top of this concept, it is easy to see the main features. Hills, forests, development, and trees are all seen around Old Faithful. A bathymetric map is like a topographic map with the contour lines representing depth below sea level, rather than height above. Numbers are low near sea level and become higher with depth. Kilauea is the youngest volcano found above sea level in Hawaii. On the flank of Kilauea is an even younger volcano called Loihi. The bathymetric map pictured in the Figure 1.2 shows the form of Loihi. Loihi volcano growing on the flank of Kilauea volcano in Hawaii. Black lines in the inset show the land surface above sea level and blue lines show the topography below sea level. A geologic map of the region around Old Faithful, Yellowstone National Park. A geologic map shows the geological features of a region (see Figure 1.3 for an example). Rock units are color- coded and identified in a key. Faults and folds are also shown on geologic maps. The geology is superimposed on a topographic map to give a more complete view of the geology of the region. Click image to the left or use the URL below. URL:
Example Output: this type of map shows rock units and features like faults and folds.
