Input: Consider Input: Question: Who designed Hans Klemm's first light aircraft? Passage:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

Input: Consider Input: Question: What is the population of the city where the East Jordan Canal is heading? Passage:State Street continues north through the Crescent neighborhood, past the site of the historic Crescent Elementary School, and enters Downtown Sandy. It intersects 10600 South, which becomes State Route 151 a short distance to the west, and passes a large retail area that includes big box stores and the South Towne Mall. The street climbs a small hill to pass over the Jordan and Salt Lake Canal, then passes a cemetery and a small amount of undeveloped greenfield land near the crossing of Dry Creek before reaching a larger hill into which the East Jordan Canal is carved. At the top of this hill, the street passes west of Jordan High School and the South Towne Expo Center before intersecting 9400 South (former State Route 209). A short distance north of that intersection, the East Jordan Canal passes back under the street on its way toward Holladay, and Rio Tinto Stadium fronts onto the street on the west side. Just before the intersection with 9000 South (modern State Route 209), State Street passes the site of a former smelter (which now has a medical center built on part of it). The street forms the western boundary of the Sandy Historic District from 9000 South to Pioneer Avenue (8530 South), and several historic buildings face onto it in this area. There is a traffic signal it the intersection with Sandy's Main Street at 8720 South. North of the historic district, State Street passes through some relatively lightly developed land near the city's border with Midvale, though there are some townhouse developments in progress in the area.

Input: Consider Input: Question: What was the full name of the music group that Dr. Dre and DJ Yella were a member of? Passage:The video begins with an introduction of Dr. Dre's music career, such as when he and fellow N.W.A member DJ Yella were in the 1980s funk group World Class Wreckin' Cru. There are also scenes of Dr. Dre and his family, such as him hugging his daughter and son and getting married. There are also snippets from past music videos. It includes many rappers such as Eazy-E, 2Pac, The D.O.C, Snoop Dogg, Warren G, Eminem, Xzibit and all the rest of the members from N.W.A. The video then features Dr. Dre driving down Pacific Coast Highway in a Ferrari 360, with flashbacks of his life, crashing his car and the last thing heard was his daughter say "Good night Daddy." Then he is transported to a medical facility. The date at the beginning of the video is February 18, 2001 (his 36th birthday). They fast-forward to present day ten years later, where he has been hospitalized and is on life support. The Marin County Civic Center stands in for the medical facility. Eminem raps next to him as he is floating in an isolation tank, during which the figure of the Pythia (played by Canadian actress Estella Warren) is singing as a hologram behind and over Dre, mouthing the words to Skylar Grey's vocal part in the song. Skylar Grey herself appears as one of the doctors in the video, but never actually appears singing her part. Dre eventually wakes up and goes through rehab, and the video ends with him standing next to the grave of Eazy-E, a rapper who had launched Dre's music career by founding N.W.A and was also a member along with Ice Cube, MC Ren and DJ Yella. A ticking clock is heard midway through the video. The music video received complaints of being an "act of advertising" for a variety of product placements, such as Ferrari, G-Shock, HP, Gatorade, and Dr. Dre's signature headphones, Beats by Dr. Dre.
