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.

[EX Q]: Passage: In late 1920, the Persian Soviet Socialist Republic in Rasht was preparing to march on Tehran with "a guerrilla force of 1,500 Jangalis, Kurds, Armenians and Azerbaijanis", reinforced by the Bolsheviks' Red Army. This fact, along with various other disorders, mutinies and unrest in the country created "an acute political crisis in the capital." By 1921, the ruling Qajar dynasty of Persia had become corrupt and inefficient. The oil-rich nation was somewhat reliant on the nations of Britain and Russia for military and economic support. Civil wars earlier in the decade had threatened the government, and the only regular military force at the time was the Cossack Brigade. The Qajar shah in 1921 was Ahmad, who had been crowned at the age of eleven. He was considered to be a weak, incompetent ruler, especially after British, Russian and Ottoman occupations of Persia during World War I. In 1911, when the capital city, Tehran, had been seized by the Russians, armed Bakhtiaris tribemen, rather than Iranian regular troops, expelled the invaders. This further diminished the government's reputation, rendering it almost powerless in time of war. Britain, which played a major role in Persia, was dismayed by the Qajar government's inability to rule efficiently. This inefficiency was the background of a power struggle between Britain and Russia, each nation hoping to control Persia. On 14 January 1921, the British General Ironside chose to promote Reza Khan, who had been leading the Tabriz battalion, to lead the entire brigade. About a month later, under British direction, Reza Khan's 3,000-4,000 strong detachment of the Cossack Brigade reached Tehran.
Question: When did Reza Khan did Tehran?

[EX Q]: Passage: On 2 May, the German capital city, Berlin, fell to the Red Army. On 8 May 1945, the Germans surrendered unconditionally and the war in Europe officially ended. The Italians had quit the war in 1943, the Bulgarians in 1944, and the Hungarians earlier in 1945. Despite the German capitulation, however, sporadic fighting still took place in Yugoslavia. On 7 May, Zagreb was evacuated, on 9 May, Maribor and Ljubljana were captured by the Partisans, and General Alexander Löhr, Commander-in-Chief of Army Group E was forced to sign the total surrender of the forces under his command at Topolšica, near Velenje, Slovenia, on Wednesday 9 May 1945. Only the Croatian and other anti-Partisan forces remained. From 10 to 15 May, the Yugoslav Partisans continued to face resistance from Croatian, and other anti-Partisan forces throughout the rest of Croatia and Slovenia. The Battle of Poljana, the last battle of World War II in Europe, started on 14 May, ending on 15 May 1945 at Poljana, near Prevalje in Slovenia. It was the culmination and last of a series of battles between Yugoslav Partisans and a large  mixed column of German Army  soldiers together with Croatian Ustaše, Croatian Home Guard, Slovenian Home Guard, and other anti-Partisan forces who were attempting to retreat to Austria.
Question: What day did the Battle of Poljana begin?

[EX Q]: Passage: Due to a conflict involving the Orioles' schedule, the Ravens opened the regular season on the road against the Broncos in what would be the first time a defending Super Bowl champion team has done so since the Buccaneers in 2003 when they opened their regular season against the Eagles.  This would be a rematch of last year's AFC Divisional game. The Ravens drew first blood when Joe Flacco found Vonta Leach on a 2-yard touchdown pass to take the lead 7-0 in the first quarter for the only score of the period.  The Broncos would tie the game in the 2nd quarter with Peyton Manning finding Julius Thomas on a 24-yard pass to take the game to 7-7.  The Ravens moved back into the lead when Ray Rice ran for a 1-yard touchdown to make the score 14-7.  Peyton would find Julius again on a 23-yard pass to make the score 14-14 for another tie before the Ravens kicker Justin Tucker nailed a 25-yard field goal to make the score 17-14 at halftime.  In the 3rd quarter, the Broncos went right back to work as Peyton found Andre Caldwell on a 28-yard touchdown pass to take a 21-17 lead followed up with finding Wes Welker on 2 consecutive passes from 5 yards and 2 yards out for an increase in the lead first to 28-17 and then to 35-17.  Later on in the quarter, Peyton would find Demaryius Thomas on a 26-yard pass to increase the lead to 42-17.  The Ravens tried to rally a comeback in the last quarter, with Flacco finding Marlon Brown on a 13-yard pass to shorten the Broncos' lead 42-24 followed up by Tucker's 30-yard field goal to make the score 42-27.  However, the Broncos wrapped things up in the game when Peyton found D. Thomas again on a 78-yard pass to make the final score 49-27.  The Ravens began their season 0-1 for the first time under John Harbaugh as head coach and Joe Flacco as their starter.  They also lost their first regular season opening game since 2007 as well as becoming the 2nd straight defending Super Bowl champion team to lose their season opener.
