Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Question: How often are new issues of the Canadian Journal of Neurological Sciences published? Passage 1:"Marry the Night" is a dance-pop and synthpop song with electro rock and house influences. The song starts out with electronic church bells and Gaga softly singing "I'm gonna marry the night/I won't give up on my life/I'm a warrior queen/Live passionately tonight." Soon the beat changes into a dance one, accompanied with techno beats, handclaps and funk music, and moves to the chorus, where Gaga stutters the line "Ma-ma-ma-marry/Ma-ma-ma-marry/Ma-ma-ma-marry the night". It was compared by Tim Jonze from The Guardian to the Eurodance song, "It's My Life" by Dr Alban, while Nicola James from MTV compared the chorus with Jennifer Lopez's 1999 single "Waiting for Tonight. In a pre-release review of certain album tracks, Peter Robinson from the NME blog wrote that Gaga channels "Whitney Houston-esque pop euphoria" into the song, notably that from the singer's musical peak.
 Passage 2:In the 1967 close season, Book was named captain following the transfer of previous captain Johnny Crossan to Middlesbrough, and was henceforth nicknamed Skip by his teammates. His first season as captain was a very successful one, leading Manchester City to their second league championship and playing every game. An Achilles injury sidelined Book for the first four months of the 1968–69 season, but he returned to the team in time for the start of their FA Cup run. In the week preceding the cup final, Book was named the 1969 Football Writers' Association Footballer of the Year Award, sharing the accolade with Dave Mackay. The following Saturday Manchester City played Leicester in the FA Cup final. Manchester City won 1–0, and captain Book lifted the trophy. The following season City became the first English team to win a European and domestic trophy in the same season, the European Cup Winners' Cup and the League Cup. Book retired from playing in 1974, passing the captaincy to Colin Bell. He made 242 football league appearances for the club, and for many years was City's most successful captain in terms of trophies won.
 Passage 3:Multi-dose versions of the vaccine contain the preservative thiomersal (also known as thimerosal), a mercury compound that prevents contamination when the vial is used repeatedly. Single-dose versions and the live vaccine do not contain this preservative. In the U.S., one dose from a multi-dose vial contains approximately 25 micrograms of mercury, a bit less than a typical tuna fish sandwich. In Canada, different variants contain five and 50 micrograms of thimerosal per dose. The use of thiomersal has been controversial, with claims that it can cause autism and other developmental disorders. The U.S. Institute of Medicine examined these claims and concluded in 2004 that the evidence did not support any link between vaccines and autism. Other reviews came to similar conclusions, with a 2006 review in the Canadian Journal of Neurological Sciences stating that there is no convincing evidence to support the claim that thimerosal has a causal role in autism, and a 2009 review in the journal Clinical Infectious Diseases stating that claims that mercury can cause autism are "biologically implausible". The U.K. National Health Service stated in 2003 that "There is no evidence of long-term adverse effects due to the exposure levels of thiomersal in vaccines." The World Health Organization concluded that there is "no evidence of toxicity in infants, children or adults exposed to thiomersal in vaccines". Indeed, in 2008 a review noted that even though thiomersal was removed from all US childhood vaccines in 2001, this has not changed the number of autism diagnoses, which are still increasing.
