I want to know the answer to the following question:
How long are the terms of local city councils that are present in all Iranian cities and villages?
All the background I'm provided with is that "The Expediency Council has the authority to mediate disputes between Parliament and the Guardian Council, and serves as an advisory body to the Supreme Leader, making it one of the most powerful governing bodies in the country.". Is that enough to answer the question?
Answer: no
