Fossilisation stands for three stages of a class: Authentic Use, Restricted Use, and Clarification and Focus.

• A. Authentic Use; Restricted Use; Clarification and Focus
• B. Advanced Usage; Reduced Use; Clarification and Framing
• C. Academic Use; Routine Use; Formal Focus
• D. Actual Use; Rehearsed Use; Clear Focus

Answer: (A)

The idea being tested is the specific sequence Delta uses to describe how learners move through a lesson in relation to language use. In this fossilisation framework, learning progresses from using language in real, meaningful communication to practicing in more controlled ways, and then to focused work on language form.

First, Authentic Use means students try to communicate as they would in real life, with real messages and interactions. It supports fluency and natural language production, even if errors appear.

Next, Restricted Use involves moving to more controlled or limited language tasks. Here learners focus on accuracy within defined boundaries—using restricted vocabulary, structures, or prompts—so they can consolidate form without the full complexity of free expression.

Finally, Clarification and Focus is where the teacher explicitly highlights the language forms that caused difficulty, provides explanations or demonstrations, and helps students notice, understand, and correct those forms. This stage prepares learners to return to authentic use with better control over the targeted features.

The option that names these three stages as Authentic Use, Restricted Use, and Clarification and Focus matches the common terminology for this learning progression, making it the best fit. Other options use terms like framing, rehearsed, academic, or reduced in ways that don’t align with the standard labeling of these stages.
