Macroeconomics Bonus Question?

Question 3 would not be "e" because Brazilians don't care for baseball cards so it would be absolutely worthless here in any period of time. Impressionist paintings are much to expensive and the cruzeiro was too weak to be compared to something expensive.

So either Loaves of bread or tractor parts and between the two, loaves of bread seam pretty reasonable to be a tradeble comodity specially in poor areas and because practically all Brazilians eat bread on a daily basis.
