Task: Question Answering
Input (English): Passage: The newly built town proved highly vulnerable to fire. Houses were made of wood, heated with stoves and lit by candles and oil lamps; water for emergencies was wanting, especially in the frozen winters. The first major fire occurred on November 25, 1897, started accidentally by dance-hall girl Belle Mitchell. She also accidentally started a second major fire on October 14, 1898, which, in the absence of a fire brigade in Dawson, destroyed two major saloons, the post-office building and the Bank of British North America at a cost of $500,000 . The worst fire occurred on April 26, 1899, when a saloon caught fire in the middle of a strike by the newly established fire brigade. Most of the major landmarks in the town were burned to the ground: 117 buildings were destroyed, with the damage estimated at over $1 million .
