Question: Was the first president still alive when Santander was elected President? Passage:The Office of the Presidency goes back to the Congress of Angostura. This quasi-constituent assembly was formed to lay the ground work for a self-ruled governing administration after independence. The Constituent Assembly was formed by regional leaders that represented areas under rebel control; these areas did not include parts of what is now Colombia, as those areas were still under Spanish control, but aimed to legislate on its behalf. Congress elected an interim-executive officer and vested this figure with the title of President. Chosen to be first President of Colombia, was General Simon Bolivar y Palacios, leader of the revolutionary forces, who up to that point was titled "Supreme Chief" for his role in the revolution. The following day, Congress elected Francisco Antonio Zea Diaz, first Vice President of Colombia. Bolivar was subsequently re-elected interim President by the Angostura Assembly on after Colombia was conquered following the Battle of Boyaca, and elected again in 1821 in a permanent interim basis, pending national elections, by the Congress of Cucuta, another constituent assembly mandated by the Angostura Assembly, and this time with elected officials representing the Colombian territories, during this time, and until 1826, the executive power was entrusted to the Vice President Francisco de Paula Santander y Omana, while Bolivar was away in battle fighting to liberate Spanish colonies in Bolivia, and Peru. Bolivar was formally elected in a national election in 1826 for a period of four years, but on 27 August 1828, Bolivar declared martial law and assumed dictatorship style powers after the Congress of Ocana failed to pass a new constitution. Bolivar eventually relinquished power in 1830, and Congress elected Joaquin de Mosquera y Arboleda as his successor, but was shortly deposed by General Rafael Urdaneta y Faria who hoped Bolivar would once again re-take power, but Bolivar not only declined the Presidency, but also shortly died, leaving Urdaneta with no mandate for power. Urdaneta ceded executive-power to the Vice President Domingo Caycedo y Sanz de Santamaria, as Congress had impeached Mosquera for his failure to prevent the coup; during this time, and until 1832 the Presidency remained vacant as there was no law for succession of power. In 1832, former Vice President Santander was elected by Congress as President of Gran Colombia, and it would be the last, since the territories of Venezuela and Ecuador broke away, which prompted the drafting of a new constitution.

Ex Output:
Chosen to be first President of Colombia, was General Simon Bolivar y Palacios, leader of the revolutionary forces, who up to that point was titled "Supreme Chief" for his role in the revolution

Question: When did the war begin that prompted the Navy to build the airport? Passage:In 1950, Admiral Arthur W. Radford, Commander-in-Chief of the United States Pacific Fleet, envisioned an naval base in the Western Pacific to enhance Seventh Fleet capabilities. The Korean War began and the Navy realized it had a need for an air station in the region. Cubi Point in the Philippines was selected, and civilian contractors were initially approached for the project. After seeing the Zambales Mountains and the surrounding jungle, they claimed it could not be done. The U.S. Navy then turned to the Seabees and was told no problem, Can do. The first Seabees to arrive were surveyors of Construction Battalion Detachment 1802. Moblie Comstruction Battalion 3 arrived on 2 October 1951 to get the project going and was joined by MCB 5 in November. Over the next five years, MCBs 2, 7, 9, 11 and CBD 1803 also contributed to the effort. They leveled a mountain to make way for a nearly runway. NAS Cubi Point turned out to be one of the largest earth-moving projects in the world, equivalent to the construction of the Panama Canal. Seabees there moved of dry fill plus another 15 million that was hydraulic fill. The $100million facility was commissioned on 25 July 1956, and comprised an air station with an adjacent pier capable of docking the Navy's largest carriers. Adjusted-for-inflation, today's price-tag for what the Seabees built at Cubi Point would be $906,871,323.53. After decades of use by American forces, Mount Pinatubo erupted in 1991, burying Cubi Point in 18-36 inches of ash. Despite this, the American government wished to keep the Subic Naval Base and signed a treaty with the Philippine government. The treaty was not ratified, however, failing by a slim margin in the Philippine Senate. Attempts to negotiate a new treaty were soon abandoned and the United States was informed that it was to withdraw within one year. U.S. forces withdrew in November 1992, turning over the facility with its airport to the Philippine government.
