PROBLEM: Passage: By the late 1950s, Covent Garden was gradually abandoning its policy of productions in the vernacular; such singers as Maria Callas would not relearn their roles in English. This made it easier for Tucker to point up the difference between the two London opera companies. While Covent Garden engaged international stars, Sadler's Wells focused on young British and Commonwealth performers. Colin Davis was appointed musical director in succession to Gibson in 1961. The repertoire continued to mix familiar and unfamiliar operas. Novelties in Davis's time included Pizzetti's Murder in the Cathedral, Stravinsky's Oedipus rex, Richard Rodney Bennett's The Mines of Sulphur and more Janáček. Sadler's Wells's traditional policy of giving all operas in English continued, with only two exceptions: Oedipus rex, which was sung in Latin, and Monteverdi's L'Orfeo, sung in Italian, for reasons not clear to the press. In January 1962, the company gave its first Gilbert and Sullivan opera, Iolanthe, on the day on which the Savoy operas came out of copyright and the D'Oyly Carte monopoly ended.  The production was well received (it was successfully revived for many seasons until 1978) and was followed by a production of The Mikado in May of the same year.The Islington theatre was by now clearly too small to allow the company to achieve any further growth. A study conducted for the Arts Council reported that in the late 1960s the two Sadler's Wells companies comprised 278 salaried performers and 62 guest singers. The company had experience of playing in a large West End theatre, such as its 1958 sell-out production of The Merry Widow that had transferred to the 2,351-seat London Coliseum for a summer season. Ten years later, the lease of the Coliseum became available.  Stephen Arlen, who had succeeded Tucker as managing director, was the primary advocate for moving the company. After intense negotiations and fund-raising, a ten-year lease was signed in 1968.  One of the company's last productions at the Islington theatre was Wagner's The Mastersingers, conducted by Goodall in 1968, which 40 years later was described by Gramophone magazine as "legendary". The company left Sadler's Wells with a revival of the work with which it had re-opened the theatre in 1945, Peter Grimes. Its last performance at the Rosebery Avenue theatre was on 15 June 1968. 
Question: What are the names of the people that wrote the opera The Mikado?

SOLUTION: Gilbert.

PROBLEM: Passage: The Creed family—Louis, Rachel, and their children Ellie and Gage—move from Chicago to rural Ludlow, Maine, after Louis is offered a job as a doctor with the University of Maine. They befriend their elderly neighbor Jud Crandall, who takes them to an isolated pet cemetery (misspelled "sematary") in the forest behind the Creed's new home.
On his first day at work, Louis encounters Victor Pascow, a jogger who has been mortally injured after being hit by a truck. He warns Louis about the pet cemetery before he dies, calling Louis by name despite the fact they have not previously met. That night, Pascow comes to Louis as a ghost and leads him to the Pet Sematary, warning him not to cross the barrier because the ground beyond is "sour". Louis awakens, assuming it was a dream, but notices his feet are covered in dirt.
During Thanksgiving while the family is gone, Ellie's cat, Church, is run down on the highway. Realizing that Ellie will be devastated, Jud takes Louis beyond the cemetery and deep into the woods, where they reach an ancient Micmac burial ground. Jud instructs Louis to bury the cat and warns him not to tell anyone else about what they have done. The next day a reanimated Church returns to the house, a shell of what he was before; he stinks, moves sluggishly, and is vicious towards Louis. Jud explains that as a boy he himself revived his beloved pet dog in the Micmac ground, and that although the cat might be different, it will save Ellie the grief of losing her favorite pet.
Sometime later, the young Gage is killed by a truck along the same highway. The family is devastated, and Jud anticipates that Louis is considering burying his son in the Micmac ground, although Louis denies it. Jud believes that introducing Louis to the ritual ground aroused the malevolent forces present there, which caused Gage's death. 
Question: Who befriends an elderly neighbor?

SOLUTION: Louis.

PROBLEM: Passage: After leaving the army in January 1919, Grainger refused an offer to become conductor of the Saint Louis Symphony Orchestra and  resumed his career as a concert pianist.  He  was soon performing around 120 concerts a year, generally to great critical acclaim, and in  April 1921 reached a wider audience by performing in a cinema, New York's Capitol Theatre. Grainger  commented that the huge audiences at these cinema concerts often showed greater appreciation for his playing than those at established concert venues such as Carnegie Hall and the Aeolian. In the summer of 1919 he led a course in piano technique at Chicago Musical College, the first of many such educational duties he would undertake in later years.Amid his concert and teaching duties, Grainger found time to re-score many of his works (a habit he continued throughout his life) and also to compose new pieces: his Children's March: Over the Hills and Far Away, and the orchestral version of The Power of Rome and the Christian Heart both originated in this period.   He also began to develop the technique of elastic scoring, a form of flexible orchestration  which enabled works to be  performed by different numbers of players and instrument types, from small chamber groups  up to full orchestral strength.In April 1921 Grainger moved with his mother to a large house in White Plains, New York. This was  his  home for the remainder of his life. From the beginning of 1922 Rose's health deteriorated sharply; she was suffering from  delusions and nightmares, and became  fearful that her illness would harm her son's career. Because of the closeness of the bond between the two, there had long been  rumours that  their relationship was incestuous;  in April 1922 Rose was directly challenged over this issue by her friend Lotta Hough. From her last letter to Grainger, dated 29 April, it seems that this confrontation unbalanced Rose; on 30 April, while Grainger was touring on the West Coast, she jumped to her death from an office window  on the 18th floor of the Aeolian Building in New York City. The letter, which began "I am out of my mind and cannot think properly", asked Grainger if he had ever spoken to Lotta of "improper love". She signed the letter: "Your poor insane mother". 
Question: What is the full name of the woman who's letter unbalanced the woman that signed her suicide note "Your poor insane mother"?

SOLUTION:
Lotta Hough.
