If the inflation rate in New Zealand were to rise relative to the inflation rate in Russia, the purchasing power of the New Zealand dollar would decrease relative to the Russian ruble. This is because higher inflation in New Zealand would generally lead to a depreciation of the New Zealand dollar.
As a result, the rubles-per-dollar exchange rate would rise (meaning it would take more rubles to buy one New Zealand dollar).
So, the correct response is:
The rubles-per-dollar exchange rate would rise since the inflation decreases the supply of dollars and increases the demand for dollars.
