What does it mean to "retrogress"?

To "retrogress" means to move backward or return to an earlier condition. This term is often used in various contexts, such as discussing social, economic, or personal development where instead of progressing or advancing, there is a regression to a previous state that may be less desirable. The essence of retrogression implies that there is a decline or stepping back in terms of improvement or growth.

The other choices do not align with the meaning of the term. Moving forward into progress suggests advancement rather than a return to a previous state. Remaining in the same position indicates stability instead of a backward movement, and advancing in technology suggests a positive progression rather than a step back. Thus, the definition that accurately captures the essence of "retrogress" is the movement backward or the return to earlier conditions.
