In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[Q]: Passage: Chris Emerson, a young former surfing pro and his younger sister Nicole move to Luna Bay, California, following the death of their parents, to live in a house owned by their aunt Jillian. Chris leaves his address at the home of Edgar Frog, the town's surfboard shaper, in hopes of getting a job. Chris is approached at their new home by former pro surfer, Shane Powers (played by Angus Sutherland the half brother of Kiefer Sutherland who played David from the original film), who invites him to a party that night.
Chris and Nicole go to the party, where Shane and his friends Kyle, Erik and Jon are entertaining themselves with the human guests. Chris showers with a girl named Lisa and Shane gets Nicole alone, chats with her for a bit, and then tricks her into drinking his blood. When Chris learns that Nicole has been with Shane, he angrily, and protectively, takes her home, where she begins to manifest vampiric strength and rage. But before Nicole kills Chris, she is knocked out by Edgar, who reveals that he is a vampire hunter, and Nicole has been infected with vampirism. Chris throws Edgar out of the house. Then, Lisa shows up and pretends to chat with Chris for a bit before she finally tries to seduce and feed on him. In fending her off, he accidentally impales her on a mounted rack of antlers, killing her explosively when she turns into stone and explodes.
Finally convinced of the situation, remembering what Edgar said and believing that he was right, Chris seeks out Edgar's help. Edgar explains that Nicole is only half-vampire, and will remain that way unless she feeds, and she can be turned human again if they kill the head vampire before that. Chris interrupts her just before she can feed on Evan Monroe, a nice guy who has been courting her, and explains what is happening to her, and Nicole is surprised at what she almost did (because she believes herself to be a vegetarian). However, Shane draws her to their lair and they have sex. 
Question: What is the name of the person that starts to manifest vampire strength?
[A]: Nicole.


[Q]: Passage: In 1947, Walton was presented with the Royal Philharmonic Society's Gold Medal. In the same year he accepted an invitation from the BBC to compose his first opera. He decided to base it on Chaucer's Troilus and Criseyde, but his preliminary work came to a halt in April 1948 when Alice Wimborne died. To take Walton's mind off his grief, the music publisher Leslie Boosey persuaded him to be a British delegate to a conference on copyright in Buenos Aires later that year.
 While there, Walton met Susana Gil Passo (1926–2010), daughter of an Argentine lawyer. At 22 she was 24 years younger than Walton (Alice Wimborne had been 22 years his senior), and at first she ridiculed his romantic interest in her. He persisted, and she eventually accepted his proposal of marriage. The wedding was held in Buenos Aires in December 1948. From the start of their marriage, the couple spent half the year on the Italian island of Ischia, and by the mid-1950s they lived there permanently.Walton's last work of the 1940s was his music for Olivier's film of Hamlet (1948). After that, he focused his attentions on his opera Troilus and Cressida. On the advice of the BBC, he invited Christopher Hassall to write the libretto. This did not help Walton's relations with the Sitwells, each of whom thought he or she should have been asked to be his librettist. Work continued slowly over the next few years, with many breaks while Walton turned to other things. In 1950 he and Heifetz recorded the Violin Concerto for EMI. In 1951 Walton was knighted. In the same year, he prepared an authorised version of Façade, which had undergone many revisions since its premiere. In 1953, following the accession of Elizabeth II he was again called on to write a coronation march, Orb and Sceptre; he was also commissioned to write a choral setting of the Te Deum for the occasion.Troilus and Cressida was presented at Covent Garden on 3 December 1954. Its preparation was dogged by misfortunes. Olivier, originally scheduled to direct it, backed out, as did Henry Moore who had agreed to design the production; Elisabeth Schwarzkopf, for whom the role of Cressida had been written, refused to perform it; her replacement, Magda László, had difficulty mastering the English words; and Sargent, the conductor, "did not seem well acquainted with the score". The premiere had a friendly reception, but there was a general feeling that Hassall and Walton had written an old-fashioned opera in an outmoded tradition. The piece was subsequently staged in San Francisco, New York and Milan during the next year, but failed to make a positive impression, and did not enter the regular operatic repertory. 
Question: What is the name of the piece that was staged in San Francisco, New York and Milan but reportedly failed to make a positive impression?
[A]: Troilus and Cressida.


[Q]: Passage: Starting approximately 40 million years ago in the middle Eocene, a braided river system called the "Ancestral Rogue River" flowed through the region where the Rogue Valley is now carved. For about 2.1 million years, the river deposited what is now known as the Payne Cliffs Formation by laying down a thin conglomerate, followed by arkosic sandstone and siltstone. Between 10 and 20 million years ago, the uplift that created the nearby Klamath Mountains caused an incision that formed the Rogue River valley. Vertical erosion, or downcutting of the Rogue River continues to keep pace with the recent uplift, with about 690 feet (210 m) of erosion occurring in the past seven million years.Approximately seven million years ago in the upper Miocene, a 44-mile (71 km) long trachyandesitic lava flow that likely came from Olson Mountain near present-day Lost Creek Lake flowed down the Ancestral Rogue River and its tributaries and spread throughout the valley. This lava formed a hard cap over the Payne Cliffs Formation. At Lost Creek Lake, the lava attained its maximum thickness of 730 feet (220 m) and thinned to about 100 to 200 feet (30 to 61 m) to the north of Medford.
 
Since the Olson eruption, the Rogue River has eroded 90 percent of the solidified lava. Though the andesite prevented much erosion to the caps of the Table Rocks, the andesite-capped cliffs eroded from the side as the softer sedimentary units of the Payne Cliffs Formation gave way. This erosion created expansive talus fields which surround the plateaus on all sides, creating slopes capable of supporting abundant plant and animal life. Upper and Lower Table Rock both stand 800 feet (240 m) above the valley floor, and just over 2,000 feet (610 m) above sea level. There are approximately 300 acres (120 ha) of level ground on Lower Table Rock, and 500 acres (200 ha) on Upper Table Rock.The Table Rocks offer an example of inverted relief, in which previous topographic lows are filled with a resistant rock and become new topographic highs after the erosion of the surrounding region. Each plateau is shaped roughly like a horseshoe because the lava followed the meanders of the Ancestral Rogue River.
Two caves and two former gold mines are located at the base of the andesite cap on Upper Table Rock. The caves were created by natural fractures in the cap, and the gold mines were excavated by prospectors searching for gold in the 19th century. Three are large enough to walk into, with an average width of 8 feet (2 m), while one is a small pit, dropping 30 feet (9.1 m) vertically into a pond of water. 
Question: What is there 500 acres of on Upper Table Rock?
[A]:
level ground.
