Which two forms of a deliberative assembly are commonly recognized?

The correct choice pertains to the forms of deliberative assemblies typically recognized within parliamentary procedure. Conventions and boards exemplify structured bodies that hold meetings to deliberate on important matters, create policies, and facilitate decision-making.

Conventions are large assemblies, often organized for specific purposes such as political engagements or conferences, bringing together a wide range of members to discuss and vote on pertinent issues. This form promotes democracy, allowing representatives from various groups to voice their opinions and influence outcomes.

Boards function similarly but are usually smaller, more focused groups established within organizations to make decisions and provide oversight on operations and governance. They often have a set agenda and operate under defined rules, enabling efficient deliberation and decision-making on specific issues.

The options reflecting committees, mass meetings, and task forces do not embody the conventional structure associated with deliberative assemblies as accurately as conventions and boards do. They serve important functions but are categorized differently in the context of formal parliamentary settings.
