In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Q: Question: How long had the Senator held his position before he helped Thurmond to try to get Schweiker off the ticket? Passage:In the 1976 Republican primary, President Ford faced a challenge from former California Governor Ronald Reagan, who selected Richard Schweiker as his running mate. Though Thurmond backed Reagan's candidacy, he, along with North Carolina Senator Jesse Helms, led efforts to oust Schweiker from the ticket. During the subsequent general election, Thurmond appeared in a campaign commercial for incumbent U.S. President Gerald Ford in his race against Thurmond's fellow Southerner, former Georgia Governor Jimmy Carter. In the commercial, Thurmond said Ford (who was born in Nebraska and spent most of his life in Michigan) "sound[ed] more like a Southerner than Jimmy Carter". After President-elect Carter nominated Theodore C. Sorensen as his choice to become Director of the Central Intelligence Agency, Thurmond expressed reservations and fellow Senator Jake Garn said he believed Thurmond would not vote for the nomination. Sorensen withdrew from consideration days later, before a vote could be had.

Q: Question: How many years did the owner of the private observatory live? Passage:It would seem that Gill's interests lay elsewhere since after a few years he sold the business, and then spent time equipping Lord Lindsay's private observatory at Dun Echt, Aberdeenshire. In 1874, Gill joined the expedition to Mauritius to observe the transit of Venus. Three years later he went to Ascension Island to observe a near approach of Mars and to calculate its distance. While carrying out these laborious calculations, he was notified of his appointment to the Cape Observatory, which, over the following 27 years he was to refurbish completely, turning it into a first-rate institution. Gill was a meticulous observer and had a flair for getting the best out of his instruments. His solar parallax observations with a heliometer and his calculations of distances to the nearer stars, are testimony to his outstanding work. He recruited Robert Innes to the Cape Observatory.

Q: Question: How many people had died in the American Civil War by the year that Camp Chase was established? Passage:Camp Chase was an American Civil War training and prison camp established in May 1861, on land leased by the U.S. Government. It replaced the much smaller Camp Jackson which was established by Ohio Governor William Dennison Jr as a place for Ohio's union volunteers to meet. It originally operated from a city park. The main entrance was on the National Road west of Downtown Columbus, Ohio. Boundaries of the camp were present-day Broad Street (north), Hague Avenue (east), Sullivant Avenue (south), and near Westgate Avenue (west). Named for former Ohio Governor, Salmon P. Chase, who was Lincoln's Secretary of the Treasury; it was a training camp for Ohio volunteer army soldiers, a parole camp, a muster outpost, and later a prisoner-of-war camp. The nearby Camp Thomas served as a similar base for the Regular Army. As many as 150,000 Union soldiers and 25,000 Confederate prisoners passed through its gates from 1861–1865. By February 1865, over 9,400 men were held at the prison. More than 2,200 Confederates are buried in the Camp Chase Cemetery. Western Virginia and Kentucky civilians suspected of actively supporting secession, including former three-term United States Congressman Richard Henry Stanton were held at the facility. The prison camp also held Confederates captured during Morgan's Raid in 1863, including Col. Basil W. Duke.
