Teacher: Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
Teacher: Now, understand the problem? If you are still confused, see the following example:
In 1582 the united provinces invited francis, duke of anjou to lead them; but after a failed attempt to take antwerp in 1583, the duke left the netherlands again. after the assassination of william of orange (10 july 1584), both henry iii of france and elizabeth i of england declined the offer of sovereignty. however, the latter agreed to turn the united provinces into a protectorate of england (treaty of nonsuch, 1585), and sent the earl of leicester as governor-general. this was unsuccessful and in 1588 the provinces became a confederacy. the union of utrecht is regarded as the foundation of the republic of the seven united provinces, which was not recognized by the spanish empire until the peace of westphalia in 1648.
Solution: In what year did francis, duke of anjou leave the netherlands?
Reason: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

Now, solve this instance: Cynthia Nelson (Mariette Hartley), a teacher at the local orphanage, talks with a pastor while watching the sun set before getting ready for a fundraising costume party. Cynthia mentions the "Santa Ana winds" which the pastor states are an evil omen. One the orphans, Tommy, wanders into the nearby cemetery where he faintly hears a voice ordering "To rise; it is time." Vampire women rise from their graves and chase Tommy into the clutches of Count Yorga, who was waiting for them. Yorga, having been in the area while creating his undead harem and hiding them in the cemetery, has purchased a manor next to the orphanage. His intent is to prey on the children and staff there to satisfy his and his vampire-brides' thirst for blood and presumably create an undead-army from the community's women. In his human guise, he goes to the orphanage during their costume party and fund raiser, biting on of the guests, Mitzi, outside the event room before introducing himself to those present to which he meets and becomes smitten with Cynthia. Upon returning to his manor and a throne room of sorts where he's greeted by his Brudah and his female vampire servants, sends his undead brides to her house, using mind-control to get Cynthia's family into one room before having the brides break in and attack them. Cynthia's father and mother are killed after being drained of their blood, while Cynthia's sister, Ellen, is fed upon and transformed into a new vampire bride to serve Yorga. Tommy, who was sleeping over, is untouched having fallen under Yorga's power, and blankly looks on as the carnage unfolds. Cynthia is subdued (though not bitten) and carried by the brides to Yorga's residence where she awakens with no memory of the attack. Yorga tells Cynthia that her family were in a car accident and she was left in his care during their recovery. Yorga tries to charm the young woman into willingly becoming his bride though he is warned by his live-in witch that Cynthia will bring his end if he doesn't kill her or turn her into a vampire soon. The next morning, Jennifer, the Nelsons' mute maid, finds the massacre scene and calls the police. By the time the police arrive though, all of the evidence has been mysteriously cleared away, and Tommy claims that nothing has happened. Later that same morning, Bruddah, Yorga's hulking, facially disfigured servant (like Yorga, also returning from an on-screen death in the first film) drags the corpses of Cynthia's mother and father to a quicksand pit on Yorga's property, disposing of the physical evidence while likewise bring Ellen's body to Yorga to complete her transformation. Despite the confusion, David Baldwin, Cynthia's fiance, is suspicious about the Nelsons' disappearance. Meanwhile, memories of the attack on her family slowly start to resurface in Cynthia's mind as she stays within Yorga's manor. Jennifer, suspicious about Tommy's involvement with the Nelson's disappearance and his visits to Yorga's mansion, loses her patience and slaps Tommy who stares at her in a vengeful manner. Meanwhile, Yorga goes to claim Mitzi, killing her boyfriend near their boat house then biting her, draining her blood and making her a new bride. Hours later, Ellen's fiance Jason is lured to Yorga's mansion by Tommy, on the promise that he would find Ellen. Once at the mansion, Tommy disappears, while Jason is reunited with Ellen. However, in her vampirized state, she is now evil and laughs at him for "not loving her anymore", distracting him before her fellow brides attack him from behind. Jason breaks free, only to run into Count Yorga, who chases Jason down a hall and strangles him. Bruddah tosses Jason's body into the throne/coffin room for the brides, including Ellen and newly vampiric Mitzi, to feed upon. That evening, Reverend Thomas phones Jennifer, but it is revealed she lay dead on her bed with a large knife sticking out of her chest. From her window, Tommy can be seen walking

Who gives Yorga the final push that sends him plummeting to the ground?
