It's important for educators to consider the test in the context of the student's overall performance and abilities in oral communication. **

This process can help to simplify the grammar and make it easier to understand and work with. Both left-factoring and left-recursion elimination are valid techniques for addressing ambiguity in context-free grammars. **
