What is required regarding the completion time for the examination?

Completion of the examination within a specified time frame ensures that all test takers are evaluated under similar conditions, promoting fairness and standardization in the assessment process. Setting a two-hour limit allows sufficient time for examinees to thoughtfully consider their responses, demonstrating their understanding and knowledge of the material related to Texas Compressed Natural Gas delivery and operations. This timeframe strikes a balance between providing ample opportunity for in-depth reflection while maintaining a sense of urgency that can help simulate real-world decision-making scenarios.

The other choices suggest varying completion times that either do not provide a structured limit (completion at any pace), or extend the time beyond what is typically necessary for a thorough examination of this kind, which could lead to inefficiencies and a less focused assessment environment.
