2009 Intercorporate Investments vs 2010 Intercorporate Investments

Did anybody notice this: Reading 21: Intercorporate Investments Every LOS from 2009 compared to 2010 is DIFFERENT, yet the 30 questions at the end of the chapter are 99.5% the SAME. Isn’t it strange that the LOSs are completely different but the questions are the same?

How different is the material in the reading?
