1. what might a citizen say in the presence of a sovereign ruler? why?

A citizen say only those things which pleases the ruler.

A citizen can't say anything in the presence of a sovereign ruler because all the powers are present in the hand of one person and no one question him about his actions so if a citizen say anything that make him unhappy then the citizen will be punished for his action of speaking. It is the democracy in which citizen can represents their ideas and say its point of view before the head of the government so we can conclude that the citizen can't speak before the sovereign ruler.
