Task: Question Generation
Input (English): Passage: In 1664, a group of missionaries led by François Pallu, Bishop of Heliopolis, also of the Paris Foreign Missions Society, joined Lambert in the capital city of Ayutthaya after 24 months overland travel and started missionary work. In 1665-66 they built a seminary in Ayutthaya with the approval of King Narai, the Seminary of Saint Joseph . In 1669, Louis Laneau, Bishop of Motella, also a member of the Paris Foreign Missions Society, was named head of a Roman Catholic mission in mainland Southeast Asia, with his headquarters at Ayutthaya. They propagated the Christian faith and also took care of Annamite Christians and Japanese Christian communities in Thailand. Narai welcomed these missionaries, providing them with land for a church, a mission-house and a seminary .Bishops Lambert and Ballue established a Western hospital in Thailand in 1669 at Ayutthaya, with Father Laneau as the head doctor. The hospital provided medical care to about 200-300 people daily. During a 1670 trip to France, Pallu obtained from Louis XIV a letter to King Narai, which, together with a letter from the Pope, he remitted in Ayutthaya in October 1673 and which was received with great reverence. These contacts were closely associated with the development of French influence in South Asia, and especially with the establishment of the French East India Company in 1664, and the development of colonial French India.
Output (English): How many years did it take to build a seminary in Ayutthaya?
