You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: What year was the company that constructed the speedway north of Talladega formed? Passage 1:Talladega Superspeedway, originally known as Alabama International Motor Superspeedway (AIMS), is a motorsports complex located north of Talladega, Alabama. It is located on the former Anniston Air Force Base in the small city of Lincoln. The track is a tri-oval and was constructed in the 1960s by the International Speedway Corporation, a business controlled by the France Family. Talladega is most known for its steep banking and the unique location of the start/finish line that's located just past the exit to pit road. The track currently hosts the NASCAR series such as the Sprint Cup Series, Xfinity Series and the Camping World Truck Series. Talladega is the longest NASCAR oval with a length of tri-oval like the Daytona International Speedway, which also is a tri-oval.
 Passage 2:"Online" is a moderate up-tempo song whose lyrics satirize the online world, specifically MySpace. Here, the song's protagonist is a geek who lives at home with his parents, holds a job at the local Pizza Pitt pizzeria, and claims limited success in the dating world. Actually "five-foot-three and overweight", a fan of science fiction, and a mild asthmatic, the main character has an account on MySpace. There, he assumes a much more desirable personality: "Online, I'm out in Hollywood / I'm six-foot-five and I look damn good / I drive a Maserati / I'm a black-belt in karate / And I love a good glass of wine". Later in the song, he claims to live in Malibu, California, have a sexy, finely sculptured body, and pose for Calvin Klein Inc. and GQ. The fictitious alternate personalities make the geek claim that he is "so much cooler online". The album version of the song ends with a marching band playing the melody of the chorus, a reference to an earlier line where the protagonist claims to play tuba in a marching band.
 Passage 3:From the bioelectricity of nerves, Marxow turned his attention, from 1876 on, to the global electrical activity of the cerebral hemispheres. Neuroanatomists had already determined at the time that its nervous tissue was also composed of cells (the neurons), with their bodies mainly located in the gray matter, and filamentary prolongations, the dendrites and the axons. Thus, it was only natural to assume that they would also display electrical activity. This important discovery, however, had not been made until that time, because many desynchronized electrical potentials with different polarities produce a cumulative global potential which is actually very small and difficult to detect with the sensitivity range of the measuring devices available at the time. Despite this, Marxow was able to prove for the first time that the peripheral stimulation of sensory organs, such as vision and hearing were able to provoke event-related small electrical potential swings on the surface of the cerebral cortex which was related to the projection of those senses. Strangely, however, Marxow did not publish his results, choosing instead to deposit them in a bank safe, with instructions to reveal them in 1883 only. Meanwhile, the first publications about what was later to be called the electroencephalogram came to light, independently demonstrated by Richard Caton (1842–1926), in Great Britain, and Adolf Beck (1863–1942) in Poland, both using laboratory animals.
