Example Input: Passage: The government of Portuguese India started in 1505, six years after the discovery of the sea route to India by Vasco da Gama, with the nomination of the first Viceroy Francisco de Almeida, then settled at Kochi. Until 1752, the name "India" included all Portuguese possessions in the Indian Ocean, from southern Africa to Southeast Asia, governed - either by a Viceroy or Governor - from its headquarters, established in Goa since 1510. In 1752 Portuguese Mozambique got its own government and in 1844 the Portuguese Government of India stopped administering the territory of Portuguese Macau, Solor and Portuguese Timor, seeing itself thus confined to a reduced territorial entity in Malabar: Goa, Daman, Diu, Dadra and Nagar Haveli. Portuguese control ceased in the last two enclaves in 1954, and finally ceased in the remaining three pockets in 1961, when they were occupied by the Republic of India . This ended four and a half centuries of Portuguese rule in partsthought tinyof India. It may be noted that during the term of the monarchy, the title of the head of the Portuguese government in India ranged from "Governor" to "Viceroy". The title of viceroy would only be assigned to members of the nobility; It was formally terminated in 1774, although it has later been given sporadically to be decisively ended after 1835), as shown below.
Question: What year was the discovery of the sea route to India by Vasco da Gama?

Example Input: Passage: The War of the Limburg Succession, was a series of conflicts between 1283 and 1289 for the succession in the Duchy of Limburg. The cause of the War of the Limburg Succession was the death of Waleran IV, Duke of Limburg in 1280, and his only daughter Ermengarde of Limburg in 1283. Waleran IV had no sons and Ermengarde had no children. Ermergarde had married Reginald I of Guelders, who now claimed the Duchy of Limburg. However, Waleran's nephew Adolf VIII of Berg, son of his elder brother Adolf VII of Berg, also claimed the Duchy. Unable to assert his claims, he sold them in 1283 to the mighty John I, Duke of Brabant. Between 1283 and 1288, several smaller confrontations occurred between both sides, none of them decisive. Meanwhile, most of the other local powers chose sides. Siegfried II of Westerburg, the Archishop of Cologne and ruler of the Electorate of Cologne, traditional enemy of the Duke of Brabant, forged an alliance with Reginald I, joined by Henry VI, Count of Luxembourg, and his brother Waleran I of Luxembourg, Lord of Ligny, as well as by Adolf, King of Germany. On the other side the Counts of Mark took the chance to affirm their independence from the Archbishop of Cologne and together with the Counts of Loon, Tecklenburg, and Waldeck allied with Brabant and Berg. The citizens of the City of Cologne, eager to emancipate themselves from the Archbishop's rule, also joined this alliance. After the decisive Battle of Worringen in 1288, won by Duke John I of Brabant and his allies, the Duchy of Limburg came in the possession of the Duke of Brabant. The City of Cologne gained its independence from the Archbishopric and finally the status of an Imperial city in 1475.
Question: How many people did Duke of Brabant forge an alliance with?
Example Output: number
