Question: Were either of the men that Slater accompanied aboard the  HMS Shearwater born in Scotland? Passage:In 1874 he accompanied the botanist Isaac Bayley Balfour and George Gulliver aboard HMS Shearwater on an expedition to observe the transit of Venus on Rodrigues. In addition to studies of the flora and fauna, Slater excavated the subfossil bones of extinct birds, including the Rodrigues solitaire (Pezophaps solitaria) and Rodrigues starling (Necropsar rodericanus). His records were used by the zoologists Albert Günther and Alfred Newton to write the first scientific description of the Rodrigues starling in 1879. During a stay in Mauritius in 1875 he and George Gulliver explored the flora, the herpetofauna, and the aquatic avifauna. In 1885 he traveled with Thomas Carter to Iceland. Based partly on his work there, he wrote the Manual of the Birds of Iceland, published in 1901. In 1897 Slater described the short-tailed parrotbill (Paradoxornis davidianus) and the sulphur-breasted warbler (Phylloscopus ricketti). Together with William Bernhardt Tegetmeier and Frederick William Frohawk, he wrote the fifth volume of British Birds With Their Nests and Eggs (1898). In 1877 Slater was elected a Fellow of the Zoological Society of London (FZS). He was also a member of the British Ornithologists' Union.

Question: What is the population of the city where Chico Alencar received the most vote as a congressman of Socialism and Liberty Party? Passage:In 2010 Wyllys was elected a federal MP, representing the Socialism and Freedom party, with an average of 13,000 votes. His election was only possible, considering the number of votes he had in 2010 elections, through the so-called "voto de legenda" (party vote), a constitutional mechanism that allows candidates who don't have a large number of votes to be elected through votes of another highly voted candidate of the same party. In Wyllys's case, the votes of another congressman of Socialism and Liberty Party, Chico Alencar, who was one of the most voted in Rio de Janeiro, helped in his election. Upon occupying a seat in the Brazilian Congress, Wyllys brought his LGBT movement activism to the scene. He started working on his political platform, which was primarily focused on the fight for LGBT rights. In so doing, he ended up confronting prominent Brazilian right-wing figures, such as pastor Silas Malafaia, a famous televangelist and national president of the Assembly of God Churches, and Jair Bolsonaro, a congressman who became Wyllys's nemesis in the Brazilian Congress. Wyllys came to the point of spiting on congressman Bolsonaro during the voting of President Dilma Roussef's impeachment. In Congress, Wyllys proposed three controversial pieces of legislation, including the regulation of prostitution, the legalization and government regulation of marijuana production, and the government financing of sex reassignment surgeries and hormonal treatment for transgender teenagers and adults.

Question: What year was the cemetery Warrington is buried in established? Passage:Lewis Warrington III, the grandson of War of 1812 naval hero Commodore Lewis Warrington, was born in Washington, D.C. and later entered the United States Army there. He was assigned to the 4th U.S. Cavalry Regiment as a second lieutenant on June 18, 1867, and then made a first lieutenant on July 31, 1869. Warrington spent most of his career on the Texas frontier and served under Colonel Ranald S. Mackenzie during the Texas-Indian Wars of the 1870s. On December 8, 1874, he and ten cavalrymen pursued a group of hostile Comanche Indians through the Muchague Valley. Both groups were riding at a full gallop and several riders of Warrington's unit were left behind. Warrington personally captured one Indian, turning him over to a trooper whose horse could not continue, and resumed the pursuit with Privates Frederick Bergendahl and John O'Sullivan. After five miles, their horses exhausted, the Comanches dismounted and decided to shoot it out with the troopers. Climbing out of the valley onto the plain, they opened fire on Warrington and his men as they climbed up after them. Warrington eventually became separated from the others and found himself at the mercy of five Comanche warriors. He was forced to fight them off single-handed and, after exhausting his ammunition, used his rifle as a club in hand-to-hand combat. Bergendahl and O'Sullivan found themselves in a similar situation and killed all but one of their attackers. O'Sullivan pursued the lone survivor but was unable to catch him. All three men received the Medal of Honor four months later, Warrington being the only officer of the Indian Wars to receive the award following the battle rather than years afterwards like other officers. Warrington died on January 5, 1879, and was buried in San Antonio National Cemetery.
