PROBLEM: Question: When was the palace that Khanh jumped over the walls of built? Passage:Khanh had long been regarded as an ambitious and unscrupulous officer. Following the partition of Vietnam, Khanh, a French-trained officer who served in the French-backed Vietnamese National Army during the First Indochina War, had rallied to support Ngo inh Diem, who became the first president of the anti-communist South Vietnam (Republic of Vietnam). He rose to become the deputy chief of staff in the Army of the Republic of Vietnam (ARVN), but his record of political loyalty was called into question. In 1960, during an attempted coup by rebel paratroopers, Khanh jumped over the walls of the Independence Palace and joined Diem during the siege, trying to negotiate an end to the stand-off with the rebels. Khanh parleyed with the rebels long enough for loyal forces to arrive from the outside the capital to suppress the uprising, but his critics contended that he was waiting to see which side would gain the upper hand and was not committed to Diem. In any case, Diem then promoted him to be the commander of II Corps. In his younger days, Khanh had joined the Viet Minh but then defected to the French colonial army after a year. Khanh claimed that he had left the Viet Minh because of its communist inclinations, but critics claimed that he was simply switching sides because the French-backed State of Vietnam offered him more opportunities for advancement.
