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.

The Polovtsy raid of 1068-1069 was only the tribe's second major raid into Rus' in 1055, but the tribesmen broke the treaty and attacked Kievan Rus' six years later, defeating Vsevolod in battle). In 1068-1069, the Polovtsy penetrated the earthwork defensive lines built up over the years by Prince Vladimir Svyatoslavich and his son, Yaroslav the Wise . They were met by a combined army of Yaroslav's sons: Grand Prince Iziaslav of Kiev and his brothers, Princes Sviatoslav Yaroslavich of Chernigov, and Vsevolod, which was defeated and fled back to Kiev in disarray. The Polovsty continued to raid throughout the area, prompting the Kievans to call on the grand prince to rearm them so they could march out and meet the threat. Iziaslav refused, prompting the rebellion. The Tale of Bygone Years , a part of The Lavrentian Chronicle, relates what happened next:

Example Input: Passage: Coming off their win over the Bengals, the Steelers stayed at home for a Week 15 intraconference duel with the New York Jets.

The Steelers took the lead in the third quarter with a 2-yard touchdown run from running back Rashard Mendenhall, but the Jets replied with quarterback Mark Sanchez getting a 7-yard touchdown run. New York took back their lead in the fourth quarter with Folk booting a 34-yard field goal, followed by linebacker Jason Taylor tackling running back Mewelde Moore in the endzone for a safety. Pittsburgh tried to rally, but the Jets defense would hold on to preserve the win.

Example Input: 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 Ayllon. 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?
