PROBLEM: Passage: Sussex has a centuries-long tradition of sport. Sussex has played a key role in the early development of both cricket and stoolball. Cricket is recognised as having been formed in the Weald and Sussex CCC is England's oldest county cricket club. Slindon Cricket Club dominated the sport for a while in the 18th century. The cricket ground at Arundel Castle traditionally plays host to a Duchess of Norfolk's XI which plays the national test sides touring England. The sport of stoolball is also associated with Sussex, which has a claim to be where the sport originated and certainly where its revival took place in the early 20th century. Sussex is represented in the Football League by Brighton & Hove Albion and Crawley Town. Brighton has been a League member since 1920, whereas Crawley was promoted to the League in 2011. Sussex has had its own football association, since 1882 and its own football league, which has since expanded into Surrey, since 1920. In horse racing, Sussex is home to Goodwood, Fontwell Park, Brighton and Plumpton. The All England Jumping Course show jumping facility at Hickstead is situated north of Brighton and Hove.
 Link Information: The course was the first permanent showground for equestrian sport in the country, opening in 1960 Question: When was the facility at Hickstead situated north of Brighton and Hove constructed?

SOLUTION: Answer: 1960

PROBLEM: Passage: When Isabella first became queen, she was only three years old. The queen mother, Maria Christina of the Two Sicilies, served as regent. The first and foremost political division of the Isabeline era was between Carlists and Cristinos (or Isabelinos), the former being supporters of Infante Carlos, Count of Molina, a rival claimant to the throne and the latter being supporters of Maria Christina and Isabella. The former supported absolute monarchism and the traditionalism of the Antiguo Régimen ("Old Regime"); they were uniformly close to the Roman Catholic Church, and generally clericalist. The latter were generally supporters of constitutional monarchy (although some, including Maria Christina herself, were more inclined toward enlightened absolutism); they were liberals of one stripe or another, ranging from liberal conservatives and those whose liberalism was strictly economic to social liberals. In the 1830s, these two groups faced off in the First Carlist War, which the Cristinos won. The terms of surrender—notably the Convention of Vergara—left an opportunity for relatively moderate Carlists to continue to play a role in the country's politics, and many did so over the ensuing decades.
 Link Information: The queen mother, Maria Christina of the Two Sicilies, served as regent. Question: What was the age of the person who was the mother of the reigning queen when she began serving as regent?

SOLUTION: Answer: 27

PROBLEM: Passage: Born in Genoa, Pellegri is a youth product of the Genoa youth academy. On 22 December 2016, he made his debut with the senior team in Serie A in a 1–0 away loss against Torino, coming on as an 88th-minute substitute for Tomás Rincón. At the age of 15 years and 280 days, he equalled the record as the youngest ever Serie A debutant, held by Roma's Amedeo Amadei since 1937. In doing so he also became the first player born in the 21st century to appear in Serie A, and the second player born in the 2000s to make his Italian top-flight debut after Moise Kean. On 28 May, he scored his first Serie A goal in a 3–2 away loss against Roma, becoming the first player born in the 21st century to ever score in Serie A, and the third youngest goalscorer ever in the Italian top flight, after Amadei and Gianni Rivera.
