Context: A head of state (or chief of state) is the public persona that officially represents the national unity and legitimacy of a sovereign state. In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch., Baron Louis Gerard De Geer of Finspång (18 July 181824 September 1896) was a Swedish statesman and writer. De Geer was born at Finspång Castle in Risinge parish. He was a lawyer, and in 1855 became president of the Göta hovrätt, or lord justice for the appellate court of Götaland. From 7 April 1858 to 3 June 1870 he was Prime Minister for Justice and again from 11 May 1875 to 20 March 1876. As a member of the nobility he took part in the Swedish Riksdag of the Estates from 1851 onwards. From 1867 to 1878 he was the member for Stockholm in the first chamber in the New Riksdag, and introduced and passed many useful reforms., Baron Gerhard Louis De Geer of Finspång ( usually known as Louis De Geer ; 27 November 1854 -- 25 February 1935 ) was a Swedish politician , who served in the first chamber of the Riksdag 1901 - 14 , was governor of Kristianstad County 1905 - 23 , and Prime Minister of Sweden for 121 days in 1920 - 1921 ., The Prime Minister (literally "Minister of the State") is the head of government in Sweden. Before the creation of the office of a Prime Minister in 1876, Sweden did not have a head of government separate from its head of state, namely the King, in whom the executive authority was vested. Louis Gerhard De Geer, the architect behind the new bicameral Riksdag of 1866 that replaced the centuries-old Riksdag of the Estates, became the first officeholder in 1876., Subject: gerhard louis de geer, Relation: brother, Options: (A) charles de gaulle (B) gerard de geer (C) louis
