[EX Q]: 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 A]: Charles.

[EX Q]: Passage: The identity of the donor has not been established, although a number of suggestions have been advanced over the last 200 years. Harbison suggests the work's small scale indicates that it functioned as a portable altarpiece rather than as a private devotional work, and thus was commissioned by or for a member of the clergy. Other art historians have argued that the donor may have been a Genoese merchant. This belief has been fed by the triptych's similarity to Giovanni Mazone's Virgin and Child altarpiece in Pontremoli, Tuscany, which may place it in the Italian region of Liguria at latest by the end of the 15th century. Damaged coats of arms on the inner frames have been linked to the Giustiniani family, known for establishing trade links with Bruges in the 14th and 15th centuries. If not commissioned by that family, historical record place the work at least in their possession by the end of the century. In the early 1800s, Frances Weale attempted to place Michele Giustiniani as the donor, however later historical research has been unable to verify his presence in Bruges around 1437, and he seems to have returned to Italy by 1430.Mid-twentieth century technical examination revealed the Giustiniani coats of arms may have been painted over an earlier heraldic design, perhaps as early as the 15th century, whose signifiance and history is now lost. Dhanens theorises that a member of the Giustiniani family may have established other associations with St. Michael and St. Catherine, advancing that they were a member of the Italian Rapondi family, whose trading house in Paris was named after St. Catherine. Their daughter, also named Catherine, married the Italian merchant Michel Burlamacchi (Bollemard in Flemish) from Lucca, who was active in Bruges. From this Dhanens theorises the piece was commissioned as a wedding gift for the couple. Documents show weavers in Wervik paid taxes to Catherine Rapondi and in September 1434, when Michele Burlamacchi was tax collector in that town, van Eyck received a stipend funded by local tax receipts, suggesting a connection. Dhanens admits the donor's identity is lost, but she says of the piece that "it could have been a gift from the husband to the wife, a pledge of his affection during his absences; or it could have been a gift from the wife to the husband, by way of protection on his travels.". 
Question: What is the last name of the person who married the Italian merchant Michel Burlamacchi?
[EX A]: Rapondi.

[EX Q]: Passage: Minnesota strongly supported the Union war effort, with about 22,000 Minnesotans serving. The 1st Minnesota Volunteer Infantry was particularly important to the Battle of Gettysburg. Governor Alexander Ramsey happened to be in Washington D.C. when Ft. Sumter was fired upon. He went immediately to the White House and made his state the first to offer help in putting down the rebellion.At the same time, the state faced another crisis as the Dakota War of 1862 broke out.  The Dakota had signed the Treaty of Traverse des Sioux and Treaty of Mendota in 1851 because they were concerned that without money from the United States government, they would starve, due to the loss of habitat of huntable game.  They were initially given a strip of land of ten miles (16 km) north and south of the Minnesota River, but they were later forced to sell the northern half of the land.  In 1862, crop failures left the Dakota with food shortages, and government money was delayed.  After four young Dakota men, searching for food, shot a family of white settlers near Acton, the Dakota leadership decided to continue the attacks in an effort to drive out the settlers.  Over a period of several days, Dakota attacks at the Lower Sioux Agency, New Ulm and Hutchinson, as well as in the surrounding farmlands, resulted in the deaths of at least 300 to 400 white settlers and government employees, causing panic in the settlements and provoking counterattacks by state militia and federal forces which spread throughout the Minnesota River Valley and as far away as the Red River Valley. The ensuing battles at Fort Ridgely, Birch Coulee, Fort Abercrombie, and Wood Lake punctuated a six-week war, which ended with the trial of 425 Native Americans for their participation in the war.  Of this number, 303 men were convicted and sentenced to death.
Episcopal Bishop Henry Benjamin Whipple pleaded to President Abraham Lincoln for clemency, and the death sentences of all but 39 men were reduced to prison terms.  On December 26, 1862, 38 men were hanged by the U.S. Army at Mankato—the largest mass execution in the United States. Many of the remaining Dakota Native Americans, including non-combatants, were confined in a prison camp at Pike Island over the winter of 1862–1863, where more than 300 died of disease. Survivors were later exiled to the Crow Creek Reservation, then later to a reservation near Niobrara, Nebraska.
A small number of Dakota Native Americans managed to return to Minnesota in the 1880s and establish communities near Granite Falls, Morton, Prior Lake, and Red Wing. However, after this time Dakota people were no longer allowed to reside in Minnesota with the exception of the meritorious Sioux called the Loyal Mdewakanton. This separate class of Dakota did not participate in the Dakota War of 1862, since they were assimilated Christians and instead decided to help some of the missionaries escape the Sioux warriors who chose to fight. 
Question: What was the name of the place that faced a crisis as the Dakota War of 1862 broke out?
[EX A]:
Minnesota.
