With the comparisons between MIST and BRIC, I put:
1. The average inflation rate in one was higher
2. The highest inflation rate is one was higher
3. One ranged (top value - bottom value) more than the other
(cant remember which I put in each one)
For the relationship between inflation and unemployment, if you ranked each category for each country in the category they were in, all of them showed a positive relationship (eg country with highest unemployment in BRICs had highest inflation, second highest unemployment had second highest inflation etc etc).
The question about rapid economic growth was basically asking you to explain why a low female labour force participation rate and a a rising population meant a huge potential for economic growth. I basically just identified the two and how each could cause economic growth (Short Run and Long run).
The question about why do Governments wants economic growth could've been a range of things. I put to increase standards of living and to raise employment (therefore reducing the amount that has to be spent on unemployment related benefits).
The one about the multiplier was that South Korean citizens had a much lower APC/higher APS (they saved more).. I don't think anything else was required as it was a state/identify question.
For the budget deficit:
GDP was 700 billion in 2010 and increased 8% in 2011 (So it was 756 billion)
Budget deficit was 9% of GDP in 2011 so 756 x 0.09 =68.04 billion US dollars
