Question: In what city was the state funeral of Raúl Alfonsín held?
Context: Ricardo Luis Alfonsín (born November 2, 1951) is an Argentine lawyer, academic and politician prominent in the Radical Civic Union.  His father, Raúl Alfonsín, was the President of Argentina from 1983 to 1989. Mohamed Alí Seineldín (Arabic: محمد علي زين الدين ) (November 12, 1933 in Concepción del Uruguay – September 2, 2009) was an Argentine army colonel who participated in two failed uprisings against the democratically elected governments of both President Raúl Alfonsín and President Carlos Menem in 1988 and 1990. Raúl Alfonsín was the president of Argentina from 1983 to 1989.  He died on March 31, 2009, aged 82.  He had lung cancer and died at his home; a massive candlelight vigil took place in the vicinity of it.  Vice president Julio Cobos, the acting president at the time, arranged three days of national mourning and a state funeral at the Palace of the Argentine National Congress.  Alfonsín was seen by 40,000 people and the senior politicians of the country; people from other countries also voiced their respect for him.  A military escort took his coffin to the La Recoleta Cemetery, and left him at the pantheon for the veterans of the Revolution of the Park. The Palace of the Argentine National Congress (Spanish: "Palacio del Congreso Nacional Argentino" , often referred locally as "Palacio del Congreso") is a monumental building, seat of the Argentine National Congress, located in Buenos Aires at the western end of Avenida de Mayo (at the other end of which is the Casa Rosada). Susana Myrta Ruiz Cerutti (born 18 November 1940) is an Argentinian lawyer, diplomat and politician, who occupied the position of Minister of Foreign Affairs and Worship ("canciller") during the presidency of Raúl Alfonsín, from 26 May to 8 July 1989.  This made her the first woman in Argentina's history to reach the post of Foreign Minister.  She previously served as Deputy Foreign Minister from 1987 to 1989, when she became Foreign Minister, and later held other positions in that Ministry.  During her diplomatic career she was also Argentinian Ambassador to Switzerland, Liechtenstein and Canada. Operation Hope Not was the code-name of a funeral plan for Winston Churchill that started in 1953, twelve years before his death in 1965.  The detailed plan was prepared in 1958.  As Prime Minister of the United Kingdom, Churchill led the country to victory in the Second World War (1939–1945).  He suffered a stroke in 1953.  The British government started meticulous preparation, as publicly decreed by Queen Elizabeth II of a commemoration "on a scale befitting his position in history."  The official project was undertaken by the Earl Marshal, Bernard Fitzalan-Howard, the Duke of Norfolk, to be the grandest state funeral for a person outside the royal family since that of Arthur Wellesley, 1st Duke of Wellington.  Churchill died on 24 January 1965, and the operation was implemented on 30 January 1965.  Churchill's coffin was kept at Westminster Hall.  The main funeral service was held at St Paul's Cathedral.  The coffin was transported by boat on the Thames to Waterloo station, and thence by train to Bladon, Oxfordshire, where it was interred in the St Martin's Churchyard, near his father's tomb.  It was the first state funeral of a British civilian in the 20th century, and at the time, recorded as the largest state funeral in the world.  The official funeral lasted for four days. Chascomús is a railway station and bus terminus in the homonymous city of Buenos Aires Province, Argentina.  Construction began on his station in 1983 when Raúl Alfonsín was President of Argentina but works were interrupted and finally cancelled until they were resumed in 2014 and the station was finished and opened to public on December 19.  Station's facilities and services include railway platforms, bus garages, accessible toilets and a coffeehouse. Raúl Borrás (b. 1933 - d. 1985) was an Argentine politician, who served as minister of defense during the presidency of Raúl Alfonsín. Propuesta y control was an Argentine magazine established in 1976 by Raúl Alfonsín and Yuyo Roulet.  Although Alfonsín was a prominent leader of the Radical Civic Union, the magazine featured editorials from people unrelated to the party. María Lorenza Barreneche Iriarte (July 3, 1926 – January 5, 2016) was an Argentine public figure and wife of the late President Raúl Alfonsín.  She held the position of First Lady of Argentina from 1983 until 1989.
