Input: Consider Input: Question: What was the population of the Hejaz region during The Battle of Badr? Passage:The Battle of Badr (), fought on Tuesday, 13 March 624 CE (17 Ramadan, 2 AH in the Islamic calendar) in the Hejaz region of western Arabia (present-day Saudi Arabia), was a key battle in the early days of Islam and a turning point in Muhammad's struggle with his opponents among the Quraish in Mecca. The battle has been passed down in Islamic history as a decisive victory attributable to divine intervention, or by secular sources to the strategic genius of Muhammad. It is one of the few battles specifically mentioned in the Quran. All knowledge of the battle at Badr comes from traditional Islamic accounts, both hadiths and biographies of Muhammad, recorded in written form some time after the battle. There is little evidence outside of these of the battle. There are no descriptions of the battle prior to the 9th century.

Input: Consider Input: Question: How old was Jennie Jerome when her granddaughter Lady Eden was born? Passage:Lady Eden was born in 1920, the daughter of Major Jack Spencer-Churchill (1880–1947), the younger brother of Winston Churchill, by his marriage to Lady Gwendoline ("Goonie") Bertie (1885–1941), a daughter of the 7th Earl of Abingdon, who had been married in 1908. She is thus a niece of Winston Churchill, who was Prime Minister during the Second World War, and a granddaughter of Lord Randolph Churchill, Chancellor of the Exchequer 1886–87, and his wife the American society beauty Jennie Jerome. Her paternal great-grandfather was the 7th Duke of Marlborough, and her maternal great-great-grandfather the 3rd Marquess of Londonderry, half-brother of the 2nd Marquess, who, as Viscount Castlereagh was Foreign Secretary during the Congress of Vienna of 1815 that followed the Napoleonic Wars.

Input: Consider Input: Question: How long had the Gestapo been established when Blachstein was arrested?  Passage:Inside the SAPD, the first part of 1937 saw an intensification of differences over attitudes to a possible political party of the united left or a Popular front, and more precisely over the party's approach to the Soviet Union. The differences led to Peter Blachstein's exclusion from the SAPD. Others excluded at the same time included his political mentor and Erwin Ackerknecht: the three became the focus of a short-lived political grouping known as "Neuer Weg" ("New Way"). Blachstein was also affected more directly by the intense political tensions radiating out from Moscow, based on Stalin's suspicions - not entirely unfounded - that there might be comrades in the Soviet Union and further west in Europe who favoured an alternative Soviet leader. The POUM, of which Blachstein was a member, backed a broadly Trotskyite vision for a communist future and its members therefore became targets for Soviet agents. In June 1937 Blachstein was arrested in Barcelona by communist secret police and accused of spying for Franco and working for the Gestapo. With approximately 100 other foreign detainees he was taken to a large garage which had been adapted for use as an ad hoc prison. Because of the appalling hygiene he soon fell ill with Tuberculosis, as a result of which he was transferred to a sanatorium controlled by anarchist comrades. Helped by Spanish friends, in January 1938 he succeeded in escaping back to France.
