I want to know the answer to the following question:
How many Federal Congressional districts was Tucson split into in 2013?
All the background I'm provided with is that "The city center is in the 3rd District, represented by Raul Grijalva, a Democrat, since 2003, while the more affluent residential areas to the south and east are in the 2nd District, represented by Republican Martha McSally since 2015, and the exurbs north and west between Tucson and Phoenix in the 3rd District are represented by Democrat Ann Kirkpatrick since 2008.". Is that enough to answer the question?
Answer: no
