What distinguishes an advisory referendum from other referendum types?

An advisory referendum is characterized by its role in allowing citizens to express opinions on policies without necessarily creating binding decisions for lawmakers. This type of referendum solicits public input on specific issues, but the results do not compel the government to act in accordance with the voters' preferences.

Unlike other referendums that may involve binding decisions or the approval of new laws, the advisory referendum is typically used as a way to gauge public sentiment or to inform legislators about the views of their constituents. This function is particularly valuable in contexts where policymakers want to understand the electorate's stance on an issue before making a decision.

In contrast, options that suggest mandatory voting or requirements for a supermajority pertain to other types of referenda or legislative procedures rather than focusing on the advisory nature of this specific referendum type.
