What type of principle does a "bastion" typically uphold?

A "bastion" commonly refers to a stronghold or a place of protection that upholds certain values, principles, or attitudes. It often represents a steadfast defense of these ideals in the face of opposition or challenges. This term is frequently used in contexts where it symbolizes unwavering support for a particular ideology or belief system. The correct choice highlights this association with specific principles or attitudes that a bastion is meant to preserve or defend, underlining its role as a stabilizing force against change or adversity.

The other options do not capture the full essence of what a bastion represents. Fleeting trends suggest impermanence and change, while mundane facts imply a lack of significance or depth, neither of which align with the concept of a bastion as a stronghold for ideals. Random opinions lack the thoughtfulness and consistency that a bastion embodies. Thus, the focus on particular principles or attitudes is what makes the chosen answer the most fitting descriptor for a bastion.
