Question: Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai.  The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North. 
Question: What is the first name of the person who unwell and unhappy during his brief tenure?

Answer: Charles.


Question: Passage: Cowboy drifter Jim Garry is summoned by his friend, smooth-talking Tate Riling. Garry rides into an Indian reservation and finds himself in the middle of a conflict between a cattle owner and some homesteaders. He meets cattle owner John Lufton, and eventually his daughters Amy and Carol. The Luftons suspect that Garry is on Riling's side and are initially hostile, especially Amy. Garry readily admits that he is going to work for his friend.
Riling tells Garry that he and Indian agent Jake Pindalest have devised an elaborate scheme to force Lufton into selling his herd cheaply. Pindalest has gotten the government to order Lufton to remove his cattle from the reservation in a week. Meanwhile, Riling has organized the homesteaders into blocking the move, conning them into believing that he is working in their best interests. With no other option, Lufton would have to sell his herd at bargain prices or lose everything. Lufton would never sell to Riling, but he would to a stranger like Garry. Pindalest would then see that the government buys the herd at an inflated price. Garry would get $10,000 for his part in the swindle.
Lufton manages to outsmart Riling and move his herd unimpeded, but Riling and his men stampede and scatter the cattle back onto the reservation. It would take several days to gather the herd, more time than Lufton has before the deadline. Garry becomes disgusted when a man is killed in the stampede, and he switches sides. Amy still does not trust him. She suspects Garry of betraying the contents of a letter to Riling, unaware that Carol is enamored with Riling and is the one passing information to him. Eventually, Amy comes to trust (and fall in love with) Garry, especially after he defends her father from two of Riling's men. 
Question: Who are the people Riling has believing that his is working in their best interest?

Answer: the homesteaders.


Question: Passage: The highlight of Doubleday's career came after 7 February 1845 when a young man, who later admitted having spent the prior week "indulging in intemperance", smashed the Portland Vase, an example of Roman cameo glass and among the most famous glass items in the world, into hundreds of pieces. After his selection for the restoration, Doubleday commissioned a watercolour painting of the fragments by Thomas H. Shepherd. No account of his restoration survives, but on 1 May he discussed it in front of the Society of Antiquaries of London, and by 10 September he had glued the vase whole again. Only 37 small splinters, most from the interior or thickness of the vase, were left out; the cameo base disc, which was found to be a modern replacement, was set aside for separate display. A new base disc of plain glass, with a polished exterior and matte interior, was diamond-engraved "Broke Feby 7th 1845 Restored Sept 10th 1845 By John Doubleday". The British Museum awarded Doubleday an additional £25 (equivalent to £2,500 in 2016) for his work.At the time the restoration was termed "masterly" and Doubleday was lauded by The Gentleman's Magazine for demonstrating "skilful ingenuity" and "cleverness ... sufficient to establish his immortality as the prince of restorers". In 2006 William Andrew Oddy, a former keeper of conservation at the museum, noted that the achievement "must rank him in the forefront of the craftsmen-restorers of his time." Doubleday's restoration would remain for more than 100 years until the adhesive grew increasingly discoloured. The vase was next restored by J. W. R. Axtell in 1948–1949, and then by Nigel Williams in 1988–1989. 
Question: What was the first name of the person who was selected to restore the Portland Vase?

Answer:
John.
