[EX Q]: Question: Which of the Churchill brothers died first? Passage:Lady Eden was born in 1920, the daughter of Major Jack Spencer-Churchill (1880–1947), the younger brother of Winston Churchill, by his marriage to Lady Gwendoline ("Goonie") Bertie (1885–1941), a daughter of the 7th Earl of Abingdon, who had been married in 1908. She is thus a niece of Winston Churchill, who was Prime Minister during the Second World War, and a granddaughter of Lord Randolph Churchill, Chancellor of the Exchequer 1886–87, and his wife the American society beauty Jennie Jerome. Her paternal great-grandfather was the 7th Duke of Marlborough, and her maternal great-great-grandfather the 3rd Marquess of Londonderry, half-brother of the 2nd Marquess, who, as Viscount Castlereagh was Foreign Secretary during the Congress of Vienna of 1815 that followed the Napoleonic Wars.

[EX Q]: Question: In what year did Jared Taylor found the American Renaissance? Passage:In February 2010, Breitbart received the Reed Irvine Accuracy in Media Award during the Conservative Political Action Conference in Washington, D.C. During his acceptance speech, he responded directly to accusations by The New York Times reporter Kate Zernike that Jason Mattera, a young conservative activist, had been using "racial tones" in his allusions to President Barack Obama, and had spoken in a "Chris Rock voice". From the podium, Breitbart called Zernike "a despicable human being" for having made such allegations about what, according to him, was just Mattera's Brooklyn accent. At the same conference, Breitbart was also filmed saying to journalist Max Blumenthal that he found him to be "a jerk" and "a despicable human being" over a blog entry in which Blumenthal accused Breitbart of employing a racist. Blumenthal was referring to James O'Keefe over his having attended a Georgetown Law Center discussion on race featuring Kevin Martin, John Derbyshire, and Jared Taylor, the last of whom founded American Renaissance, an online magazine widely considered white supremacist. Neither O'Keefe nor Breitbart endorsed Taylor's views.

[EX Q]: Question: What kind of aircraft were leased? Passage:In addition to withdrawing from the prestigious long-haul routes to New York and Los Angeles after only 18 months, other specific measures the airline took at the time to ensure its survival included dropping all scheduled flights to Belfast, Copenhagen, Gibraltar, Ibiza, Málaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the Glasgow—Southampton route as well as cutting the number of frequencies on the Gatwick—Glasgow and Gatwick—Edinburgh routes from six to four daily round trips. Two surplus aircraft were leased out to Air Malta and Austrian Airlines respectively for the duration of the 1975 summer timetable period. Another aircraft was stationed at West Berlin's Tegel Airport during the month of July of that year to fulfill a short-term charter contract to carry Turkish migrant workers to and from Istanbul on behalf of a local tour operator. BCal also decided to increase its 707 freighter fleet from one to four aircraft and to acquire a five-seater Piper Aztec to serve the rapidly growing executive charter market. These changes left BCal with 25 operational aircraft for the 1975 summer season. To reduce operating costs further, the airline decided to contract out its scheduled operations between Gatwick and Le Touquet to BIA. The reason for replacing BCal's One-Eleven 200 jet aircraft on this route with that airline's Herald turboprops at the beginning of the 1975 summer timetable period was the high price of jet fuel, which had made BCal's own jet aircraft operations uneconomic.
