Structured natural language is a way of writing system requirements where:

The freedom of the requirements writer is limited and all requirements are written in a standard way using templates, maintaining expressiveness while ensuring uniformity

Requirements are written in a formal mathematical notation

Requirements are written as executable code that defines the system behavior

Requirements are drawn as UML diagrams without any text

Correct Answer

The freedom of the requirements writer is limited and all requirements are written in a standard way using templates, maintaining expressiveness while ensuring uniformity

Explanation

Structured natural language limits the freedom of the requirements writer so that all requirements are written in a standard way. This approach maintains most of the expressiveness and understandability of natural language while ensuring some uniformity is imposed on the specification.
