I want to know the answer to the following question:
How many teams played in the 2011 domestic Samoan rugby league competition?
All the background I'm provided with is that "Rugby league is mostly played by Samoans living in New Zealand and Australia,[citation needed] with Samoa reaching the quarter finals of the 2013 Rugby League World Cup made of players playing in the NRL, Super League and domestic players.". Is that enough to answer the question?
