Input: Consider Input: Question: What countries signed the treaty that acknowledges Ireland's "traditional policy of military neutrality"? Passage:Ireland has been neutral in international relations since the 1930s. The nature of Irish neutrality has varied over time, and has been contested since the 1970s. Historically, the state was a "non-belligerent" in the Second World War (see Irish neutrality during World War II) and has never joined NATO, although during the Cold War it was anti-communist and aloof from the Non-Aligned Movement. The compatibility of neutrality with Ireland's membership of the European Union has been a point of debate in EU treaty referendum campaigns since the 1990s. The Seville Declarations on the Treaty of Nice acknowledge Ireland's "traditional policy of military neutrality", reflecting the narrow formulation of successive Irish governments. Others define Irish neutrality more broadly, as having "a strong normative focus, with a commitment to development, United Nations peacekeeping, human rights and disarmament".

Input: Consider Input: Question: Which baseball team that played in the 1924 World Series had won the most League pennants? Passage:The 1924 World Series was the championship series of the 1924 Major League Baseball season. A best-of-seven playoff, the series was played between the American League (AL) pennant winner Washington Senators and the National League (NL) pennant winner New York Giants. The Senators defeated the Giants in seven games to win their first championship in club history. The Giants became the first team to play in four consecutive World Series, winning in 1921–1922 and losing in 1923–1924. Their long-time manager, John McGraw, made his ninth and final World Series appearance in 1924. The contest concluded with the second World Series-deciding game which ran to extra innings (the first had occurred in 1912). Later, the Senators would reorganize as the Minnesota Twins, again winning the World Series in 1987 and in 1991.

Input: Consider Input: Question: In what year was the university established where Friedrich Hornemann studied Arabic. Passage:Hornemann was born in Hildesheim, a city in Lower Saxony, Germany, located about 30 km southeast of Hannover. He was a young man when, early in 1796, he offered his services to the African Association of London as an explorer in Africa. The African Association sent him to the University of Göttingen to study Arabic and otherwise prepare for an expedition from the east into the unknown regions of North Africa. In September 1797 he arrived in Egypt, where he continued his studies. When the country was invaded by the French, he was confined in the citadel of Cairo to preserve him from the fanaticism of the populace. Liberated by the French, he received the patronage of Bonaparte. On 5 September 1798 he joined a caravan returning to the Maghreb from Mecca, attaching himself to a party of Fezzan merchants who accompanied the pilgrims. As an avowed Christian would not have been permitted to join the caravan Hornemann assumed the character of a young mamluk trading to Fezzan. He then spoke, but indifferently, both Arabic and Turkish, and he was accompanied as servant and interpreter by Joseph Freudenburg, a German convert to Islam, who had thrice made the pilgrimage to Mecca. Travelling by way of the oases of Siwa and Aujila, a black rocky desert was traversed to Temissa in Fezzan. Murzuk was reached on 17 November 1798.
