What does "stringent" mean when referring to rules?

The term "stringent" when applied to rules refers to conditions or regulations that demand strict adherence and precision. This means that the rules are often rigorous, requiring individuals to follow them closely without leniency or flexibility. "Stringent" emphasizes the importance of compliance and the seriousness with which these rules must be followed.

By contrast, the other options signify interpretations of rules that lack the strictness associated with "stringent." For example, being "flexible and open to interpretation" suggests a more lenient approach that allows for variations in understanding, while "complicated and hard to understand" implies confusion rather than strictness. Lastly, describing rules as "outdated and irrelevant" does not align with the concept of stringent regulations, as it suggests they are not currently applicable or necessary. Thus, the definition that aligns best with "stringent" is that of demanding strict attention to rules and procedures.
