reading 18 question 8 (cfai book) into, long, understand, different, concerned

stockjaguar

can someone walk me through the solution to this question. Maybe taking a different approach. I do not get the flow of argument here. As far as i was concerned question asked which country would have higher gwoth rate in the future if trend continued.
well clearly croatia no? (crotia gdp has higher growth from q1 to q2 and is same trend continues it will still have higher growth in future.
solution makes several tables and goes into a fairly long winded argument which i do not understand. can someone please explain. much appreciated.
thanks
