Answer 5

I have no idea about Ecuador but I know it is North of Peru, just above it, if you look at the map of South America. Then, Bolivia is just SE of Peru. In fact it shares the Lake Titicaca with Peru (one half of the lake belongs to Peru and the other half to Bolivia). A friend who is originally from Bolivia told me that Peruvian culture and foods etc are so similar to those of Bolivia.
