Passage: On 28 July 2012, Jin won the gold medal in the men's 10 m air pistol at the 2012 Summer Olympics. On 5 August, he won the gold medal in the 50m, becoming the first man to successfully defend the 50-metre pistol Olympic title. By doing so, Jin also became the first man to win the 10 metre air pistol and 50 metre pistol gold medals at the same Olympics, and one of the five shooters to win two individual gold medals at one Olympics, being the first man to have done so since Otto Olsen of Norway at the 1920 Summer Olympics. He is one of three shooters to have won three Olympic individual gold medals, along with Ralf Schumann of Germany and Kim Rhode of the United States. He became the first Korean athlete to win three individual Olympic gold medals, to win four (and five) individual Olympic medals, to defend an individual title in the Summer Olympics (while Sim Kwon-Ho won Olympic gold medals for Greco-Roman wrestling in 1996 and 2000, he won two different weight divisions), to win two individual gold medals at one Summer Olympic Games and to win an individual medal for one event at three consecutive Olympic Games (Kim Soo-Nyung won individual gold, silver and bronze medals respectively for archery in the 1988, 1992 and 2000 but these Olympics were non-consecutive).

Answer: Kim Rhode

Passage: Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence – Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" – those who had sided with Simon de Montfort, 6th Earl of Leicester.
 Link Information: Martin of Pattishall (died 14 November 1229) was an English judge.

He took his name from the village of Pattishall in Northamptonshire and was the clerk of Simon of Pattishall, although they were apparently unrelated. By 1201 he was already respected enough to be collecting the Plea rolls from the clerks of other judges on Eyre. After the end of the First Barons' War Pattishall became the leader of Henry III's professional legal servants, and was instrumental in reestablishing the courts. Between 1217 and 1218 he was a justice on Eyre in Yorkshire and Question: Which of Bracton's predecessors served in their position the longest?
Answer: Raley

Passage: For the rest of her long career, Ancona served in a variety of roles, both in the main fleet and in Italy's colonial empire. After the end of the war, the government lost confidence in the fleet and drastically reduced the naval budget. The cuts were so severe that the fleet had great difficulty in mobilizing its ironclad squadron to attack the port of Civitavecchia in September 1870, as part of the wars of Italian unification. Instead, the ships were laid up and the sailors conscripted to man them were sent home. Some time after 1866, the ship was rebuilt as a central battery ship, with most of her guns located in a central, armored casemate. Two other guns were placed in the bow as chase guns, with a third mounted as a stern chaser. At around 1871, her armament was also revised, to two guns in the bow and eight 8 in guns, four on each broadside and the last in the stern. Later, her armament was changed again, to eight guns, six guns, four quick firing (QF) guns, and two Hotchkiss revolver cannons. Ancona was stricken from the naval register in 1903 and then broken up for scrap.
 Link Information: 1867 Garibaldi made a second attempt to capture Rome, but the papal army, strengthened with a new French auxiliary force, defeated his poorly armed volunteers at Mentana. Subsequently, a French garrison remained in Civitavecchia until August 1870,  Question: How long did the war where Ancona attacked the port of Civitavecchia last?

Answer: 3
