Question: Passage: From 1623 to 1624 the Dutch had been at war over the Pescadores, and in 1633 clashed with a fleet led by Zheng Zhilong in the Battle of Liaoluo Bay, ending in another Dutch defeat. By 1632 the Dutch had established a post on a peninsula named Tayoan , which was separated from the main part of Formosa by a shallow lagoon historically referred to as the Taikang inland sea. The Dutch fortifications consisted of two forts along the bay: the first and main fortification was the multiple-walled Fort Zeelandia, situated at the entrance to the bay, while the second was the smaller Fort Provintia, a walled administrative office. Frederick Coyett, the governor of Taiwan for the Dutch East India Company, was stationed in Fort Zeelandia with 1,800 men, while his subordinate, Valentyn, was in charge of Fort Provintia and its garrison of 500 men. In 1659, after an unsuccessful attempt to capture Nanjing, Koxinga, son of Zheng Zhilong and leader of the Ming loyalist remnants, felt that the Qing Empire had consolidated their position in China sufficiently, while his troops needed more supplies and manpower. He began searching for a suitable location as his base of operations, and soon a Chinese man named He Bin , who was working for the Dutch East India Company in Formosa , fled to Koxinga's base in Xiamen and provided him with a map of Taiwan.
Question: Which forts belonged to the Dutch?

Answer: span

Question: Passage: The Melbourne Storm played two marquee games at the MCG in 2000. This was the first time that they had played outside of their normal home ground of Olympic Park Stadium which held 18,500 people. Their first game was held on 3 March 2000 against the St. George Illawarra Dragons in a rematch of the infamous 1999 NRL Grand Final. Dragons player Anthony Mundine said the Storm were not worthy premiers and they responded by running in 12 tries to two, winning 7010 in front of 23,239 fans. This was their biggest crowd they had played against until 33,427 turned up to the 2007 Preliminary Final at Docklands Stadium which saw Melbourne defeat the Parramatta Eels 2610. The record home and away crowd record has also been overhauled, when a match at Docklands in 2010 against St George attracted 25,480 spectators. Their second game attracted only 15,535 spectators and was up against the Cronulla Sharks on 24 June 2000. Once again, the Storm won 2216.
Question: What year was the rematch of the NRL Grand Final played?

Answer:
date
