question:
Question: How long had the Rodin Museum been around for by the year Auguste Rodin created a bust of Lord Howard de Walden? Passage:After succeeding to his family titles in 1899 he inherited further estates in 1901, including property in Marylebone, London and earned the title of 'Britain's wealthiest bachelor'. His family's wealth was initially derived from slavery and sugar estates in Jamaica, primarily Montpelier, Jamaica. He took a lease on Audley End House, Essex which had once belonged to his ancestors, in 1904 but reportedly never felt settled there. The artist Auguste Rodin created a bust of Lord Howard de Walden in 1906 which is held in the collection kept at the Rodin Museum in Philadelphia. In 1911, in preparation for his marriage, he leased Chirk Castle, Denbighshire, which became his main residence after WWI until 1946, and where he learned the Welsh language; he later served as president of the Campaign for the Protection of Rural Wales from 1931 to 1945.

question:
Question: Which country designed the fighter planes that the Yugoslav Air Force used but were badly maintained? Passage:An important portion of the 1999 war between Yugoslavia and the NATO coalition involved combat between the Yugoslav Air Force, which was the predecessor of today's Serbian Air Force, and the opposing air forces of NATO. United States Air Force F-15s and F-16s flying mainly from Italian air force bases attacked the defending Yugoslav fightersusually MiG-29s, which were in bad shape, due to lack of spare parts and maintenance. A total of six Yugoslav MiG-29s were shot down in 1999, of which three were shot down by USAF F-15s, one by a USAF F-16, and one by a RNAF F-16. One aircraft, according to a Serbian documentary, was hit by friendly fire from the ground. Another four were destroyed on the ground. During the course of the air war, Yugoslav anti-aircraft defenses downed a USAF F-16C and an F-117 Nighthawk, the first stealth aircraft to ever be shot down in combat.
