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 Portnoy when he began playing drums from Dream Theater? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.
