Input: Question: Was Kontinen's mixed doubles partner at Wimbledon older than his male doubles partner? Passage 1:During this time, Portugal was not part of a group of teams that were candidates to win titles, but from 2000 until this present day, the team evolved, being present in all the final stages of major tournaments, due to the presence of several world-class players such as Luís Figo, Rui Costa, Deco, Ricardo Carvalho, and Cristiano Ronaldo, who were dubbed as Portugal's golden team, who were considered as the best of the world at their time and among the best in history. Portugal's golden team helped Portugal reach the semi-finals of Euro 2000, losing 3–2 after extra time to eventual winners France, securing the second place at Euro 2004 Final after losing to Greece on home soil, as well reaching the semi-finals of the 2006 World Cup losing to finalist France, after a penalty, leading Portugal to secure the fourth place in the tournament, after losing to 3–1 to hosts Germany, thus being the best result since the 1966 World Cup. Despite losing many players of the golden team, new players such as Fábio Coentrão, João Moutinho, Nani and Pepe helped the Portuguese reach the semi-finals of Euro 2012, losing to Spain in penalties, with Cristiano Ronaldo finishing as joint top scorer of the tournament with three goals. 
 Passage 2:His good results continued in 2016 as he won the title at the Brisbane International in January with John Peers. On April–May they won the BMW Open together. At the 2016 Wimbledon Championships he reached quarterfinals of the men's doubles tournament together with Peers and the final of the mixed doubles with Heather Watson, which they won in straight sets. On July Kontinen and Peers won the German Open Tennis Championships. On August Kontinen won the Winstom-Salem Open playing with Guillermo García-López. It was Kontinen's 10th doubles title in his career. He took the victory of St. Petersburg Open with Dominic Inglot. Kontinen and Peers had a successful end for the year as they won their first Masters title at Paris Masters and the season ending ATP World Tour Finals title. Kontinen reached the top 10 in rankings as a first Finnish tennis player ever.
 Passage 3:Olson made one CART World Series start in 1983 at Road America. In 1984 he drove in three Can-Am races, an IMSA GT Championship race and two World Endurance Championship races, including the 1984 24 Hours of Le Mans where he was caught up in the debris field of his Aston Martin teammate John Sheldon's crash that killed a track worker. In 1985 he won three races with Dyson Racing in IMSA Camel GTP, the team's first, in a Porsche 962. 1986 saw Olson continue in IMSA GTP with Dyson and Preston Henn fielding his entries. That year he also competed in the 1986 24 Hours of Le Mans, co-driving a Rothmans Porsche factory 962 with Vern Schuppan. Olson was away from racing after that until 1989 when he returned with the All American Racers Toyota 88C factory team in IMSA GTP. He won two poles and finished ninth in points. 1990 would be his final year of professional racing as he finished tenth in GTP points with three poles for All American Racers in their Eagle HF89.
