forecasting interest rates

Hi John. Could you give me some insight on some of the Chp 22 revision questions? I would really appreciate it. 1. "If a country's exchange rate falls, domestic inflation rises". What is the rationale here? (I do not understand why this would be the case). 2. "Inflation rates are a better predictor than interest rates of future exchange rates". Again, in simple terms, why is that? Thank you.
