Question: How many years did the war last where the castle was strengthened in the middle of it? Passage:In 1575, in the middle of the Wars of Religion, the castle was strengthened. It was nevertheless besieged and taken by the Geuzen, locally known as the Hurlus in 1579, before being taken back three months later. In 1627, Philip IV of Spain promoted the seigneury to the rank of county. The Franco-Dutch War under Louis XIV devastated this mostly agricultural region. Mouscron and the surrounding area became French after the Treaty of Aix-la-Chapelle (1668). Part of it rejoined the Southern Netherlands after the Treaty of Nijmegen (1678), which drew the frontier right through its territory. It was finally completely ceded to the Southern Netherlands under the terms of the Treaty of Utrecht in 1713. The textile industry started in Mouscron in the 1760s thanks to the imposition by Lille of a ban on the fabrication of molletons, a mixture of flax and wool, in Roubaix and Tourcoing. With the Battle of Fleurus (1794), Mouscron went back to France.

Question: In which venue was the wild card game played in 2014? Passage:Despite having claimed the Wild Card spot on the final day of the regular season, the Giants were able to tab ace Madison Bumgarner for the Wild Card game start. Bumgarner had an excellent regular season for the Giants, finishing with a career-low in ERA and a career-high in strikeouts, finishing fourth in the National League in both categories. On the hill for the New York Mets was Noah Syndergaard, who himself finished 3rd in the NL in ERA and 9th in strikeouts. The pitching matchup didn't disappoint, it took until the bottom of the third inning for the game's first hit and baserunner, with Syndergaard striking out four straight batters on two occasions. The closest either side came to scoring was in the top of the 6th when, after Denard Span singled and stole second base with two outs, Brandon Belt hit a long fly ball to center field which was caught on the dead run by Curtis Granderson, smashing into the wall and holding on. Syndergaard exited after 7 innings, having struck out 10. Crucially as it turned out, the Giants had forced Syndergaard out of the game with Bumgarner still going strong. Another golden opportunity was squandered by the Giants in the top of the 8th inning, when Addison Reed struck out Hunter Pence to end the inning with the bases loaded. After Bumgarner left a runner in scoring position in the bottom of the 8th, the game moved to the 9th with the Mets bringing in closer Jeurys Familia. Brandon Crawford led the inning off with a double to left-center, but Ángel Pagán couldn't lay down the sacrifice bunt and then struck out. Joe Panik worked a walk and Conor Gillaspie stepped up to the plate to launch a three-run home run to right field. Gillaspie had only started the game because Eduardo Núñez was still dealing with a hamstring injury and had to be left off the roster. Bumgarner then got the final three outs, completing the shutout just as he had done in the 2014 Wild Card Game. Bumgarner made 119 pitches, allowed just 6 total baserunners, striking out 6 and setting an MLB record of 23 consecutive scoreless innings pitched in postseason elimination games. With the win, the Giants equalled the Major League record for consecutive postseason series wins with 11, also extending their streak of postseason elimination game wins to 9.

Question: Is the king who conquered England older than his half-brother who he granted the Studland? Passage:The first records of inhabitants on Brownsea Island occurred in the 9th century, when a small chapel and hermitage were built by monks from Cerne Abbey near Dorchester. The chapel was dedicated to St Andrew and the only resident of the island was a hermit, who may have administered to the spiritual welfare of sailors passing through Poole Harbour. In 1015, Canute led a Viking raid to the harbour and used Brownsea as a base to sack Wareham and Cerne Abbey. In the 11th century the owner of the island was Bruno, who was Lord of the Manor of Studland. Following his invasion of England, William the Conqueror gave Studland, which included Brownsea, to his half-brother, Robert de Mortain. In 1154, King Henry II granted the Abbot of Cerne the right of wreck for the island and the abbey continued to control the interests of Brownsea for the following 350 years.
