[EX Q]: Question: What is the birth date of the other Polish RSDLP delegate who didn't go to London? Passage:Yakov Hanecki was born in Warsaw, then in the Russian Empire, the son of Stanislav von Fürstenberg, a beer manufacturer of German descent, who had adopted Poland as his homeland. In 1896 he joined the Social Democracy of the Kingdom of Poland (SDKP - later the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL)) led by Rosa Luxemburg and her lover, Leo Jogiches. He moved to Germany in 1901 and studied in rapid succession at Berlin, Heidelberg, and Zurich universities. From 1902, he was a professional revolutionary, normally based in Cracow, under Austrian rule, organising the transport of illegal literature across the Russian border. In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels. The Congress later adjourned to London, under pressure from the Belgian police, and there the RSDLP split into its Bolshevik and Menshevik factions, but Hanecki and the other Polish delegate, Adolf Warski, did not make the journey to London, having failed to agree terms on which the RSDLP and SDKPiL could collaborate.

[EX Q]: Question: Was Lord Howe an Admiral when the Battle of Rhode Island occurred? Passage:John Cooke was baptised on 5 March 1762 at St. Mary, Whitechapel, the second son of Francis Cooke, an Admiralty clerk, and his wife Margaret. John Cooke first went to sea at the age of eleven aboard the cutter under Lieutenant John Bazely, before going ashore to spend time at Mr Braken's naval academy at Greenwich. He was entered onto the books of one of the royal yachts by Sir Alexander Hood, who would become an enduring patron of Cooke's. In 1776 he obtained a position as a midshipman on the ship of the line , aged thirteen. Cooke served aboard Eagle, the flagship of the North American Station, during the next three years, seeing extensive action along the eastern seaboard. Notable among these actions were the naval operations around the Battle of Rhode Island in 1778, when Eagle was closely engaged with American units ashore. He distinguished himself in the assault, causing Admiral Lord Howe to remark "Why, young man, you wish to become a Lieutenant before you are of sufficient age." On 21 January 1779, Cooke was promoted to lieutenant and joined in the East Indies under Sir Edward Hughes, but was forced to take a leave of absence due to ill-health.
