In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Question: Passage: From 1722 to 1724, brief armed conflicts between the Natchez and French were settled through negotiations between Louisiana governor Bienville and Natchez war chief Tattooed Serpent. In 1723, Bienville had been informed that some Natchez had harassed villagers, and he razed the Natchez village of White Apple and enslaved several villagers, only to discover that the alleged harassment had been faked by the colonists to frame the Natchez. One of the later skirmishes in 1724 consisted of the murder of a Natchez chief's son by a colonist, to which the Natchez responded by killing another Frenchman named Guenot. Bienville then sent French soldiers from New Orleans to attack the Natchez at their fields and settlements, and the Natchez surrendered. Their plea for peace was met following the execution of one of their chiefs by the French.Chronicler Le Page du Pratz, who lived among the Natchez and was a close friend of Tattooed Serpent, records that he once asked his friend why the Natchez were resentful towards the French. Tattooed Serpent answered that the French seemed to have "two hearts, a good one today, and tomorrow a bad one", and proceeded to tell how Natchez life had been better before the French arrived. He finished by saying, "Before the arrival of the French we lived like men who can be satisfied with what they have, whereas today we live like slaves, who are not suffered to do as they please." The most faithful ally of the French, Tattooed Serpent died in 1725, another blow to the relations between the Natchez and the colonists.According to archaeologist Karl Lorenz, who excavated several Natchez settlements, another factor that complicated relations between the Natchez and the colonists was the fact that the French did not well understand the Natchez political structure. The French assumed that the Great Sun, the chief of the Grand Village, also held sway over all the other Natchez villages. In truth, each village was semi-autonomous, and the Great Sun's power only extended to the villages of Flour and Tioux (with which the Grand Village was allied) and not to the three pro-British villages of White Apple, Jenzenaque and Grigra. When the Great Sun died in 1728 and was succeeded by his inexperienced nephew, the pro-British villages became more powerful than the pro-French villages centered at Natchez.

Answer: What was the name of the person that enslvaed several villagers?


Question: Passage: The CIA is secretly developing "Crossbow", a space shuttle-mounted laser weapon precise enough to incinerate a single target from outer space, planning to use it for illegal political assassinations. However, they struggle with its power source, and have covertly hired Professor Jerry Hathaway at Pacific Technical University to develop this. Hathaway has assembled a group of genius students in physics to do the work for him, though outside of his graduate student Kent, purposely does not tell them the reason for their research. Hathaway is also embezzling the CIA provided funds intended for research so that he can upgrade his house.
Hathaway recruits high-school student Mitch Taylor to join the team. Mitch is roomed with Chris Knight, a "legend" in the physics area. Mitch becomes dismayed that Chris is more of a goof-off than a hard-working student. Chris introduces Mitch to some of the other genius students, including Jordan, "Ick" Ikagami, and his nemesis, the less intelligent Kent. Despite his age and inexperience, Hathaway assigns Mitch to lead the team due to his fresh and inventive ideas, hoping that he will remind Chris of how he used to be.

Answer: What is the man who hired the genius students helping to develop?


Question: Passage: In 1982, at Elder's instigation, Harewood appointed David Pountney director of productions. In 1985 Harewood retired, becoming chairman of ENO's board the following year.  Peter Jonas succeeded Harewood as managing director. The 1980s leadership team of Elder, Pountney and Jonas became known as the "Powerhouse", initiated a new era of "director's opera". The three of them favoured productions described, contrastingly, by Elder as "groundbreaking, risky, probing and theatrically effective", and by the director Nicholas Hytner as "Euro-bollocks that never has to be comprehensible to anybody but the people sitting out there conceiving." Directors who did not, in Harewood's phrase, "want to splash paint in the face of the public" were sidelined. A 1980s audience survey showed that the two things that ENO audiences most disliked were poor diction and the extremes of "director's opera".
In the Grove Dictionary of Music and Musicians, Barry Millington has described the 'Powerhouse' style as "arresting images of dislocated reality, an inexhaustible repertory of stage contrivances, a determination to explore the social and psychological issues latent in the works, and above all an abundant sense of theatricality." As examples, Millington mentioned Rusalka (1983), with its Edwardian nursery setting and Freudian undertones, and Hansel and Gretel (1987), its dream pantomime peopled by fantasy figures from the children's imagination  ... Lady Macbeth of the Mtsensk District (1987) and Wozzeck (1990) exemplified an approach to production in which grotesque caricature jostles with forceful emotional engagement.
Poor average box-office sales led to a financial crisis, exacerbated by backstage industrial relations problems. After 1983, the company ceased touring to other British venues. Assessing the achievements of the 'Powerhouse' years, Tom Sutcliffe wrote in The Musical Times:
ENO is not second best to Covent Garden. It is different, more theatrical, less vocal. ... The ENO now follows a policy like Covent Garden's in the early years after the war, when Peter Brook was scandalising the bourgeoisie with his opera stagings. The last two seasons at the ENO have been difficult, or at any rate sentiment has turned against the outgoing regime over the last nine months. Audience figures are well down. ... The presiding genius of the Elder years has, of course, been David Pountney. Not because his productions were all marvellous. Perhaps only a few were. But because, like Elder, he enabled so many other talents to thrive.

Answer:
What are the first names of the two people who along with Elder became known as the "Powerhouse?"?
