Question: Who won the World Cup where the Costa Rican team had a prominent performance? Passage:Since the late 1980s, the team has continuously been visible as a solidly competitive side, with a prominent performance in the 1990 FIFA World Cup in Italy, making it to the knockout stage in their debut after finishing second in their group during the first phase, below Brazil. They also managed to qualify for the 2002 and 2006 FIFA World Cups. In 2014, Costa Rica made their best performance in history by finishing first in their group that consisted of three former World Cup champions: Uruguay, Italy, and England. During the Round of 16 they defeated Greece 5–3 via a penalty shootout after a 1–1 draw. Moreover, during the match against a much better team, Navas saved more than 15 shots due to the Costa Rican very weak defense. The match was characterized as "Navas vs Greece". They reached the quarterfinals for the very first time as the Ticos were defeated by the Netherlands also in a penalty shootout (3–4) after a scoreless draw on 5 July. Their 2018 World Cup campaign ended in a 4th place group stage exit with their only point coming from a 2-2 draw vs Switzerland.

Question: How old was First King Carol when the Romanian War of Independence began? Passage:The idea of a national cathedral first emerged following the Romanian War of Independence (1877–1878), which was mainly fought between the Russian and Ottoman Empires. The church was to symbolise the victory of Orthodox Christians over the Ottoman Muslims. The idea was shelved for lack of consensus on design, location and funding. The Unification of the Romanian Principalities in 1859, entailed a unitary organization of church structures in Moldavia and Wallachia within the Holy Synod (1872), thus the assembly of hierarchs increased to 12 members, including: the Primate Metropolitan (chairman), the Metropolitan of Moldavia and their suffragan bishops of Râmnic, Buzău, Argeș, Roman, Huși and Lower Danube (Galați) and one auxiliary vicar-bishop for every diocese. The old Metropolitan Cathedral had proved overcrowded, especially during the national holidays, such as the Proclamation of the Kingdom of Romania and the crowning of the First King Carol I (10 May 1881), when none of the over one hundred churches in Bucharest were able to receive those who would have wanted to participate in the official service. Therefore, at King Carol I's desire, Romania's Assembly of Deputies and the Senate voted in favour of the Law no.1750 on the construction of the Cathedral Church in Bucharest, promulgated by King Carol I on 5 June 1884.
