Instructions: 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.
Input: Question: Which network was broadcasting first, the one Sam & Mark hosted Saturday morning children's shows on, or the network they made their debut on? Passage 1:The episode was written by Nell Scovell and directed by Wes Archer. In the episode, Bart and Lisa sneak into the sushi bar's karaoke room and sing the theme song to the 1971 film Shaft, "Theme from Shaft". The Fox network censors originally did not want the staff to use the song because they thought the lyrics were too obscene for television. In order to prove the censors wrong and show that it could appear on television, the staff dug up footage from an old Academy Awards ceremony at which the song was performed by Isaac Hayes. When the chef at the sushi bar finds out Homer has been poisoned, he yells at his apprentices in Japanese. The staff wanted the language they spoke to be actual Japanese, so they hired a Japanese actor who translated the lines for them. The episode introduced the character Akira, who has appeared many times later on the show. American actor George Takei provided the voice of Akira, although the character was voiced in later episodes by Hank Azaria. The episode featured many other guest appearances; Larry King as himself; Sab Shimono as the sushi bar chef; Joey Miyashima as Toshiro, the apprentice chef who slices up the fugu; and Diane Tanaka as hostess of the bar. King's role was first offered to American singer Bruce Springsteen, but he turned it down. According to showrunner Sam Simon, actor William Shatner also rejected the part.
 Passage 2:Robert Hues (1553 – 24 May 1632) was an English mathematician and geographer. He attended St. Mary Hall at Oxford, and graduated in 1578. Hues became interested in geography and mathematics, and studied navigation at a school set up by Walter Raleigh. During a trip to Newfoundland, he made observations which caused him to doubt the accepted published values for variations of the compass. Between 1586 and 1588, Hues travelled with Thomas Cavendish on a circumnavigation of the globe, performing astronomical observations and taking the latitudes of places they visited. Beginning in August 1591, Hues and Cavendish again set out on another circumnavigation of the globe. During the voyage, Hues made astronomical observations in the South Atlantic, and continued his observations of the variation of the compass at various latitudes and at the Equator. Cavendish died on the journey in 1592, and Hues returned to England the following year.
 Passage 3:Despite this reversal, the two have managed to carve a successful television career for themselves, hosting various programmes on the BBC, most notably Saturday morning children's shows TMi and Top of the Pops Reloaded. They made their national television debut on ITV1. Sam & Mark hosted CBBC's weekday morning breakfast show, Level Up for four months from 3 April 2006 to 1 September 2006. On 16 September 2006, they hosted the first episode of TMi, a new Saturday morning TV show for the BBC on BBC Two and the CBBC Channel, alongside presenter Caroline Flack. The third series of the show ended in December 2008 and the BBC have confirmed a fourth series of the Saturday morning series for CBBC. In 2007, Sam & Mark presented a show on CBBC called Do Something Different. Beginning on 3 January 2009, Sam and Mark's Who Wants to be a Superhero? began to air where children had to compete to be a new superhero for Stan Lee. They were also asked to perform on Children in Need 2007.
