Question: Passage: The castle was built in the 13th century by Premysl Otakar II or his son Vaclav II to guard royal paths and local mines. The first known owner was Mikulas Winkler, burgrave of Loket Castle, who sold Hauenstejn to the monastery in Doksany. The monastery exchanged it for another building with King John of Luxemburg. His son Charles IV enlarged the castle's domain. The castle frequently changed its keepers in the second half of the 14th century and the 15th century but it more or less remained royal property. The rich family of Slik that started silver mining near Jachymov won the castle in the 16th century. The Sliks rebuilt the castle in the Renaissance style after a fire in 1600. In 1663 the Sliks sold the castle to the Saxe-Lauenburg ducal family and it became part of the Ostrov domain. The castle was in the hands of the Baden family from 1689. When the last male member of the family died in 1771, the property of the Badens in Bohemia was inherited by the royal family of Maria Theresa. The Habsburgs sold it to the Buquoy family in 1837. Countess Gabrielle Buquoy started to rebuild the castle in a Romantic style. Ferdinand Buquoy continued the reconstruction under the influence of historism, taking its examples from England (Windsor, Arundel, Belvoir, Lancaster or Oxford) and Bavaria (Hohenswangau, Lahneck).

Question: Passage: In 1839, Lin Zexu, who himself was a Fuzhou native, was appointed by the Daoguang Emperor to enforce the imperial ban on the opium trade in Canton. His unsuccessful actions, however, precipitated the disastrous First Opium War with Great Britain, and Lin, who had become a scapegoat for China's failure in war, was exiled to the northwestern section of the empire. The Treaty of Nanjing (1842), which put an end to the conflict, made Fuzhou (then known to Westerners as Foochow) one of five Chinese treaty ports, and it became completely open to Western merchants and missionaries. was one of the most important Protestant mission fields in China. On January 2, 1846, the first Protestant missionary, Rev. Stephen Johnson (missionary) from ABCFM (), entered the city and soon set up the first missionary station there. ABCFM was followed by the Methodist Episcopal Missionary Society that was led by Revs. M. C. White and J. D. Collins, who reached Fuzhou in early September 1847. The Church Missionary Society also arrived in the city in May 1850. These three Protestant agencies remained in Fuzhou until the communist revolution in China in the 1950s, leaving a rich heritage in Fuzhou's Protestant culture. They supported the creation of hospitals and schools, including the Woolston Memorial Hospital, run by the American-trained Hu King Eng.
