Which phrase represents a key pair of keywords in procedural rules?

• A. Or & And
• B. May & Must
• C. Or & And
• D. And & Could

Answer: (C)

In procedural rules, the language relies on simple logical connectors to show how a process can proceed—what options exist and what must happen. The pair Or and And is the best representation because Or signals an acceptable alternative path, while And requires multiple conditions to be met at the same time. Together they capture the essential way rules describe both flexibility and required steps: you can satisfy a rule by choosing one of several options (or), and you must meet all of several conditions (and). Other options mix modality or don’t emphasize the fundamental logical tools that structure procedural steps, so they don’t fit as neatly as this pair. For example, a rule might say a filing is valid if the document is served and a certificate of service is attached, or if service is waived and a separate notice is provided, illustrating how or and and work together to describe the process.
