Question: Which of the American Indian peoples that inhabited Colombia is the oldest? Passage 1:Colombia has been inhabited by various American Indian peoples since at least 12,000 BCE, including the Muisca, Quimbaya, and the Tairona, along with the Inca Empire that expanded to the southwest of the country. Spaniards arrived in 1499 and by the mid-16th century annexed part of the region, establishing the New Kingdom of Granada, with Santafé de Bogotá as its capital. Independence from Spain was achieved in 1819, but by 1830 the Gran Colombia Federation was dissolved, with what is now Colombia and Panama emerging as the Republic of New Granada. The new sovereign state experimented with federalism as the Granadine Confederation (1858), and then the United States of Colombia (1863), before the Republic of Colombia was finally declared in 1886. Panama seceded in 1903, leading to Colombia's present borders. Beginning in the 1960s, the country suffered from an asymmetric low-intensity armed conflict and political violence, both of which escalated in the 1990s. Since 2005, there has been significant improvement in security, stability, and rule of law.
 Passage 2:Fraser was born on 10 May 1947 in Surbiton, Surrey, the second son of Harry MacKenzie Fraser, a London solicitor, and Ada Alice Gittins of Pontypool in the county of Monmouthshire. His brother was Malcolm Fraser (1939–2012), Emeritus Professor of Opera at the University of Cincinnati and co-founder of the Buxton Festival. At the age of eight, Robert Fraser won a choral scholarship to Winchester Cathedral, where he sang the daily services while studying at the Pilgrims School in the Close. Among his fellow choristers were the future newscaster Jon Snow and international tenor Julian Pike. After attending Kingston Grammar School Fraser went on to the University of Sussex to read English with David Daiches and Anthony Nuttall. He later wrote a doctorate on tradition in English poetry at Royal Holloway, University of London where the college's famous gallery of Victorian paintings was to inspire his illustrated volume of poetry The Founders’ Gift: Impressions from a Collection (2017). Simultaneously with his doctorate he studied Harmony, Counterpoint and Composition at Morley College with Melanie Daiken and James Iliff.
 Passage 3:The Victor Emmanuel Railway, which included both the Culoz–Modane railway across Savoy and the Turin–Modane railway across Piedmont, was largely built in the 1850s by the Kingdom of Sardinia and named after its king, Victor Emmanuel II. Until 1860 Sardinia included both Savoy and Piedmont. The line from Turin to Susa was inaugurated on 22 May 1854. Work on the tunnel began on 31 August 1857 and was completed in September 1871. Work had begun on the line between Bussoleno and Bardonecchia in 1867 and was completed at the same time as the tunnel. The tunnel and line were opened on 16 October 1871. By that time, the Savoy side of the tunnel had become part of France. The decision of the engineers to begin the line at Bussoleno in order to reduce the gradient on the climb near Meana was much criticized for bypassing the city of Susa, which was left isolated on a short branch line. The opening of the tunnel also led to the closure of the short-lived Mont Cenis Pass Railway. In 1865 the line became part of the network of the Società per le strade ferrate dell'Alta Italia (Upper Italian Railways, SFAI) on its foundation in 1865 and was taken over by the Rete Mediterranea (Mediterranean Network) in 1885. Finally in 1905 it became part of the Ferrovie dello Stato network.
