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?

Ex Output:
Charles.

Passage: Manitoba ( (listen)) is a province at the longitudinal centre of Canada. It is often considered one of the three prairie provinces (with Alberta and Saskatchewan) and is Canada's fifth-most populous province with its estimated 1.3 million people. Manitoba covers 649,950 square kilometres (250,900 sq mi) with a widely varied landscape, stretching from the northern oceanic coastline to the southern border with the United States. The province is bordered by the provinces of Ontario to the east and Saskatchewan to the west, the territories of Nunavut to the north, and Northwest Territories to the northwest, and the U.S. states of North Dakota and Minnesota to the south.
Aboriginal peoples have inhabited what is now Manitoba for thousands of years. In the late 17th century, fur traders arrived on two major river systems, what is now called the Nelson in northern Manitoba and in the southeast along the Winnipeg River system. A Royal Charter in 1670 granted all the lands draining into Hudson's Bay to the British company and they administered trade in what was then called Rupert's Land. During the next 200 years, communities continued to grow and evolve, with a significant settlement of Michif in what is now Winnipeg. The assertion of Métis identity and self-rule culminated in negotiations for the creation of the province of Manitoba. There are many factors that led to an armed uprising of the Métis people against the Government of Canada, a conflict known as the Red River Rebellion. The resolution of the assertion of the right to representation led to the Parliament of Canada passing the Manitoba Act in 1870 that created the province.
Manitoba's capital and largest city, Winnipeg, is the eighth-largest census metropolitan area in Canada. Other census agglomerations in the province are Brandon, Steinbach, Portage la Prairie, and Thompson. 
Question: What are the names of the three prairie provinces?

Ex Output:
Manitoba.

Passage: Annie, Marisa, and Kelly are three rowdy, raunchy, and rebellious best friends determined not to take crap from anyone and always have each other's backs.

Exhilarated, the three vow to open their college acceptance letters together at their own epic senior bash in four years.
Years later, it is now the last day of the girls senior year of high school. Annie and Marisa are still best friends, but Kelly has stopped talking to both of them and is now the most popular girl in school. Each of them receives a letter from a different university - Annie, a talented cellist with excellent grades, receives a letter from Cornell; Marisa, who is unmotivated and didn't apply to any colleges until the last minute, receives a letter from Fresno State University; while Kelly gets a letter from Stanford, pleasing her overbearing mother. Annie is determined to keep the friends promise and open the letters at the senior party, but Marisa, bitter over Kelly cutting them out of her life, is annoyed by Annie constantly talking about the pact. Meanwhile, Kelly remembers how the school guidance counselor only signed her application to Stanford on the terms that Kelly would honor her pact with Annie and Marisa after Annie wrote about their friendship for her personal essay.
