A proposed change to the Main Motion.

• A. Amendment
• B. Primary Amendment
• C. Substitution
• D. Modification

Answer: (B)

In this area of parliamentary procedure, you modify a main proposal by introducing an amendment. When that change is the first, direct alteration to the main motion itself, it’s referred to as a primary amendment. The term signals it’s the initial level of modification to the main motion, not a change to an amendment or a replacement of the motion.

Think of it this way: if the motion is about adopting a policy, proposing to add a funding clause is a primary amendment to the main motion. If someone then proposes changes to that added clause, that would be a secondary amendment to the amendment. If instead you wanted to replace the entire motion with a new proposal, that would be a substitution, not a simple modification. And “modification” isn’t a formal distinct motion type in standard rules.

So the best fit for “a proposed change to the Main Motion” is identifying it as a primary amendment—the initial alteration to the main motion.
