A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992.

Input: Consider Input: Passage: Henry VI, elected King of the Romans since 1169, succeeded his father Frederick and was crowned Holy Roman Emperor by Pope Celestine III in 1191. In his struggle with the Princes to enforce his succession, the tide turned in his favour when the returning crusader King Richard was captured in Austria and only released against an oath of allegiance and an enormous ransom. In 1194 Henry could assert the inheritance claims of his wife Constance by conquering the Kingdom of Sicily. By declaring a new Crusade to reconquer Jerusalem, Henry aimed at an agreement with Pope Celestine III to acknowledge his rule over Sicily. In 1195 the armistice concluded by King Richard ended. Sultan Saladin had already died in 1193 and a conflict over his succession raged in the Ayyubid lands. In view of these favourable developments, the emperor hoped to continue the momentum of the previous campaign. Henry VI decided to take advantage of his father's threat of force against  the Byzantine Empire, affected by the rebellions in Serbia and Bulgaria as well as by Seljuk incursions. Emperor Isaac II Angelos had maintained close ties with the Sicilian ursurper king Tancred of Lecce, he was overthrown in April 1195 by his brother Alexios III Angelos. Henry took the occasion to exact tribute and had a threatening letter sent to the Byzantine emperor in order to finance the planned Crusade. Alexius immediately submitted to the tributary demands and exacted high taxes from his subjects to pay the Crusaders 5,000 pounds of gold. Henry also forged alliances with King Amalric of Cyprus and Prince Leo of Cilicia. 
Question: How many years did the armistice with King Richard last? 
Answer type: Number 

Output: 2.


Input: Consider Input: Passage: The southeast corner of Siberia south of the Stanovoy Range was twice contested between Russia and China. Hydrologically, the Stanovoy Range separate the rivers that flow north into the Arctic from those that flow south into the Amur River.  Ecologically, the area is the southeastern edge of the Siberian boreal forest with some areas good for agriculture. Socially and politically, from about 600 AD, it was the northern fringe of the Chinese-Manchu world. Various Chinese dynasties would claim sovereignty, build forts and collect tribute when they were strong enough.  The Ming dynasty Nurgan Regional Military Commission built a fort on the Northern bank of the Amur at Aigun, and established an administrative seat at Telin, modern Tyr, Russia above Nikolaevsk-on-Amur. Russian expansion into Siberia began with the conquest of the Khanate of Sibir in 1582.  By 1643 they reached the Pacific at Okhotsk. East of the Yenisei River there was little land fit for agriculture, except Dauria, the land between the Stanovoy Range and the Amur River which was nominally subject to the Qing dynasty. In 1643, Russian adventurers spilled over the Stanovoy Range, but by 1689 they were driven back by the Qing. The land was populated by some 9,000 Daurs on the Zeya River, 14,000 Duchers downstream and several thousand Tungus and Nivkhs toward the river mouth. The first Russians to hear of Dauria were probably Ivan Moskvitin and Maxim Perfilev about 1640. In 1859/60 the area was annexed by Russia and quickly filled up with a Russian population. 
Question: How many years passed between getting to the Stanovoy Range and the Qing pushing them back? 
Answer type: Number 


Output: 46.
