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.

Question: When did the captain who allegedly discovered Falkland Islands died? Passage:The Falkland Islands have been claimed and occupied by several nations throughout its history, who generally used their national flags on the islands. It wasn't until 1876 that the islands were given a flag of their own, which consisted of a Blue Ensign defaced with the seal of the islands - an image of HMS Hebe (which brought many of the early British settlers to the islands, including Richard Moody, in the 1840s) in Falkland Sound, overlooked by a bullock (representing feral cattle which once roamed the islands). A new coat-of-arms for the islands was introduced on 16 October 1925, consisting of the Desire (which was captained by John Davis who is reputed to have discovered the islands in 1592) and a sea lion in a shield surrounded by the motto of the islands, Desire the Right. This coat-of-arms later replaced the image of the bullock and ship on the flag.
