This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Passage: Government efforts to lower subsidies to unprofitable enterprises and to shrink the money supply caused the semi-official exchange rate for the Cuban peso to move from a peak of 120 to the dollar in the summer of 1994 to 21 to the dollar by year-end 1999. The drop in GDP apparently halted in 1994, when Cuba reported 0.7% growth, followed by increases of 2.5% in 1995 and 7.8% in 1996. Growth slowed again in 1997 and 1998 to 2.5% and 1.2% respectively. One of the key reasons given was the failure to notice that sugar production had become uneconomic. Reflecting on the Special period Cuban president Fidel Castro later admitted that many mistakes had been made, "The country had many economists and it is not my intention to criticize them, but I would like to ask why we hadn’t discovered earlier that maintaining our levels of sugar production would be impossible. The Soviet Union had collapsed, oil was costing $40 a barrel, sugar prices were at basement levels, so why did we not rationalize the industry?" Living conditions in 1999 remained well below the 1989 level.
Question: Where year was the Cuban peso exchange rate higher, 1994 or 1999?

Passage: The Central Powers launched a crushing offensive on 26 October 1917, spearheaded by the Germans, and achieved a victory at Caporetto . The Italian Army was routed and retreated more than 100 kilometres  to reorganise, stabilising the front at the Piave River. Since the Italian Army had suffered heavy losses in the Battle of Caporetto, the Italian Government ordered conscription of the so-called '99 Boys : all males born in 1899 and prior, who were 18 years old or older. In 1918, the Austro-Hungarians failed to break through in a series of battles on the Piave and were finally decisively defeated in the Battle of Vittorio Veneto in October. On 1 November, the Italian Navy destroyed much of the Austro-Hungarian fleet stationed in Pula, preventing it from being handed over to the new State of Slovenes, Croats and Serbs. On 3 November, the Italians invaded Trieste from the sea. On the same day, the Armistice of Villa Giusti was signed. By mid-November 1918, the Italian military occupied the entire former Austrian Littoral and had seized control of the portion of Dalmatia that had been guaranteed to Italy by the London Pact. By the end of hostilities in November 1918, Admiral Enrico Millo declared himself Italy's Governor of Dalmatia. Austria-Hungary surrendered on 11 November 1918.
Question: When did the Italian Navy destroyed much of the Austro-Hungarian fleet stationed in Pula?

Passage: With this victory, John I was recognised as the undisputed king of Portugal, putting an end to the interregnum and anarchy of the 1383-1385 crisis. Recognition from Castile would not arrive until 1411, after another Portuguese victory at the Battle of Valverde, with the signing of the Treaty of Ayllón. The English-Portuguese alliance would be renewed in 1386 with the Treaty of Windsor and the marriage of John I to Philippa of Lancaster, daughter of John of Gaunt. In 1387, taking advantage of the renewed alliance, John I, leading a Portuguese army of 9,000 men, reinforced by a 1,500-man English contingent that landed in Galicia, invaded Castile to sit John of Gaunt on the Castilian throne, which he claimed on his marriage to Infanta Constance of Castile. The Castilian forces refused to offer battle, after two months no significant town was taken and the allies, struck by disease and lack of supplies, met with an overwhelming failure. The treaty, still valid today, established a pact of mutual support between the countries: Indeed, Portugal would use it again against its neighbours in 1640, to expel the Spanish Habsburg kings from the country, and again during the Peninsular War. The Anglo-Portuguese Alliance would also be used by Britain  in the Second World War  and during the 1982 Falklands War.
Question: In which two years was the Anglo-Portuguese alliance used?
