I want to know the answer to the following question:
In what year did IBM acquire Kenexa?
All the background I'm provided with is that "IBM acquired Kenexa (2012) and SPSS (2009) and PwC's consulting business (2002), spinning off companies like printer manufacturer Lexmark (1991), and selling off product lines like its personal computer and x86 server businesses to Lenovo (2005, 2014).". Is that enough to answer the question?
