I want to know the answer to the following question:
When did the second line of Metrobus open?
All the background I'm provided with is that "Line 2 opened in December 2008, serving Eje 4 Sur, line 3 opened in February 2011, serving Eje 1 Poniente, and line 4 opened in April 2012 connecting the airport with San Lázaro and Buenavista Station at Insurgentes.". Is that enough to answer the question?
Answer: yes
