I want to know the answer to the following question:
By when did the Portuguese unemployment rate pass the 10% mark?
All the background I'm provided with is that "By December 2009, unemployment had surpassed the 10% mark nationwide in the wake of worldwide events, by 2010, the rate was around 11% and in 2011 it was above 12%.[citation needed]". Is that enough to answer the question?
Answer: yes
