[Q]: Passage: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.  Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey. 
Question: What are the types of whales that use throat pleats to expand the mouth?
[A]: Baleen.


[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?
[A]: Charles.


[Q]: Passage: Wyoming's territorial Governor Francis E. Warren visited Rock Springs on September 3, 1885, the day after the riot, to make a personal assessment. After his trip to Rock Springs, Warren traveled to Evanston, where he sent telegrams to U.S. President Grover Cleveland appealing for federal troops. Back in Rock Springs, the riot had calmed, but the situation was still unstable. Two companies of the United States Army's 7th Infantry arrived on September 5, 1885. One company, under the command of a Lieutenant Colonel Anderson, was stationed in Evanston, Wyoming; the other, under a Colonel Chipman, was stationed in Rock Springs. At Camp Murray, Utah Territory, Colonel Alexander McDowell McCook was ordered to augment the garrison sent to Wyoming with six more companies.On September 9, 1885, one week after the massacre, six companies of soldiers arrived in Wyoming. Four of the six companies then escorted the Chinese back to Rock Springs. Once back in Rock Springs, the Chinese laborers found scorched tracts of land where their homes once stood. The mining company had buried only a few dead; others remained lying in the open, mangled, decomposing, and partially eaten by dogs, hogs, or other animals.The situation in Rock Springs was stabilized as early as September 15, when Warren first requested the removal of federal troops, but the mines at Rock Springs remained closed for a time. On September 30, 1885, white miners, mostly Finnish immigrants who were members of the Knights of Labor, walked out of mines in Carbon County, Wyoming, in protest of the company's continued use of Chinese miners. In Rock Springs, the white miners were not back at work in late September, because the company still used Chinese labor. Rock Springs steadily became quieter, and, on October 5, 1885, emergency troops, except for two companies, were removed. However, the temporary posts of Camp Medicine Butte, established in Evanston, and of Camp Pilot Butte, in Rock Springs, remained long after the riot. Camp Pilot Butte closed in 1899 after the onset of the Spanish–American War.The labor strike was unsuccessful, and the miners went back to work within a couple of months. The national Knights of Labor organization refused to support the Carbon strike and the hold out by white miners in Rock Springs following the Rock Springs Riot. The organization avoided supporting the miners along the Union Pacific Railroad, because it did not want to be seen as condoning the violence at Rock Springs. When the Union Pacific Coal Department reopened the mines, it fired 45 white miners connected to the violence. 
Question: What nationality were the miners in Carbon County?
[A]:
Finnish.
