Question: What year was the monument that commemorated French victory at the Battle of Grand Port completed?  Passage:During the Napoleonic wars, Île de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The raids (see Battle of Pulo Aura and Mauritius campaign of 1809–1811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Île de France together with its territories including Rodrigues and Seychelles to Great Britain. The island then reverted to its former name, 'Mauritius'.

Question: Is serpentine blue like Boron? Passage:The earliest recorded blue diamond, the Hope Diamond, was discovered in India, in the Kollur mine in the Guntur district of Andhra Pradesh (which at the time was part of the Golconda kingdom), in the seventeenth century. However, blue diamonds have also been discovered in the Cullinan Mine in South Africa and the Golconda region. A few blue diamonds have been discovered in the Argyle Mine in Western Australia as well, and are offered at their annual Argyle Tender when they are found. It is thought that blue diamonds, unlike most other diamonds, are formed in the lower part of Earth’s mantle, and that the boron creating their blue color originates from serpentinite carried down to the mantle by subducting ocean tectonic plates.

Question: Who was the goalkeeper for Shelbourne in 2007? Passage:Beginning his career in England with Everton in 1997, three years later he moved on to Port Vale, having never turned out for the first team at Everton despite winning caps for the Republic of Ireland under-21s and lifting the FA Youth Cup. He spent four years with Vale, and did make 39 first team appearances, though was never their first choice keeper. He also spent time on loan at Macclesfield Town, but never made it onto the field. He returned to Ireland in 2004 to sign a contract with Shelbourne, who he helped to the League of Ireland title in 2006. He spent 2007 with Waterford United, though returned to Shelbourne the following year. The "Shels" had been demoted in his absence, and he was the goalkeeper in the 2011 season, as they won promotion back into the top-flight. He joined Bohemians in time for the 2013 season, before returning to Shelbourne again in 2017 and helpign the club to win promotion as League of Ireland First Division champions in 2019. He was named on the PFAI First Division Team of the Year for the 2009 and 2018 seasons.
