Input: Consider Input: Question: Who was the oldest among those players who tied for second highest scorer in FIFA World Cup qualifying? Passage:Alexis Sánchez is a Chilean professional footballer who represents the Chile national football team as a striker. Nicknamed El Niño Maravilla ("The Boy Wonder"), he made his debut for his country in a 1–0 victory over New Zealand in April 2006. His first international goal came on his eighth appearance for Chile when he scored Chile's only goal in a 2–1 defeat to Switzerland in a friendly tournament in Vienna. , Sánchez is his country's top scorer and has the most caps, with 43 goals in 132 appearances. He passed the previous record of 37, held by Marcelo Salas, when he scored the opening goal against Germany in the group stage of the 2017 FIFA Confederations Cup in June 2017. He scored most recently against Ecuador in a 2–1 win during the 2019 Copa América. Despite Sánchez scoring seven goals, making him second-equal top scorer in 2018 FIFA World Cup qualifying (along with Lionel Messi, Gabriel Jesus and Felipe Caicedo), Chile failed to qualify for the finals. Sánchez made his most recent and 132nd appearance for Chile in a 0–0 draw against Colombia in October 2019.

Input: Consider Input: Question: What was the age difference between the commodore and his brother? Passage:Samuel Shaw was a Revolutionary War naval officer who, along with Richard Marven, were the first whistleblowers of the infant United States. As a whistleblower, Shaw was instrumental in the Continental Congress' passage of the first whistleblower protection law in the United States. Shaw, a midshipman, and Marven, a third lieutenant in the Continental Navy, were moved to act after witnessing the torture of British prisoners of war by Commodore Esek Hopkins, then Commander-in-Chief of the Continental Navy. Shaw and Marven were both from Rhode Island, as was Hopkins, whose brother was Stephen Hopkins, Governor of the new state, and a signatory to the Declaration of Independence. For reporting the misconduct of the Navy's highest officer, Shaw and Marven were both dismissed from the Navy. Worse still, Hopkins then filed a criminal libel suit against Shaw and Marven in the Rhode Island Courts.

Input: Consider Input: Question: How many children do both of the architects who designed obelisks have between them? Passage:The first obelisks may start to appear in the later 16th century and it is suggested that the obelisk on Compton Pike is Elizabethan in date. More securely dated is a series of obelisks which start to appear in the 18th century. The first of these was the Wakeman obelisk of 1702 by Nicholas Hawksmoor, which is set in the square at Richmond, Yorkshire. Probably several hundred obelisks exist in the British Isles dating from 18th and early 19th centuries. Most of these obelisks, which are often landmarks commemorate famous people and their achievements. At Stowe in Buckinghamshire an obelisk was erected in memory of Wolfe's victory at Quebec in 1752, while at the death of the Duke of Cumberland in 1765 was noted by an obelisk at Englefield Green in Surrey. Thomas Coke, Earl of Leicester, Coke of Norfolk the farming pioneer has a particularly fine obelisk, set up in the park he created at Holkham in Norfolk. Sometimes an obelisk was used to mark the site of a battle such as the obelisk on the site of English Civil War battlefield at Naseby in Leicestershire. Occasionally obelisks are used as mile markers, as on the Great North Road at a mile from Westminster. In Lincoln an elaborate obelisk was set up on the High Bridge in 1762–63 as a conduit for dispensing water, while Anthony Salvin used obelisks as water fountains on the Belton House estates in Lincolnshire.
