What does the text indicate about the relationship between the investigation and the implementation of language changes?

The correct choice highlights that the investigation serves as a necessary step before any potential changes can happen regarding language implementation. In the context of the text, this suggests that a thorough examination or assessment is essential to understanding the current state of language use before making informed decisions about changes. This process ensures that any modifications are based on solid evidence and insights gained from the investigation, allowing for a more effective implementation that aligns with the needs and circumstances identified during the investigation.

By understanding the relationship in this manner, it allows for a structured approach where the investigation informs and guides the implementation, preventing hasty decisions that could arise from a lack of understanding. Other options, like suggesting that investigation and implementation are the same or that results will be applied immediately, overlook the crucial preparatory role that investigation plays. Similarly, indicating that no further discussions will take place contradicts the idea that ongoing dialogue and analysis are necessary to refine and effectively implement changes.
