Phrase Analysis:
- "To keep pace": This phrase is commonly used to mean staying up-to-date or in synchronization with changes or developments. It makes sense in the context of needing to adapt to an ever-changing world.
Incorrect Alternative Phrases:
- "To keep place": This phrase is not standard English; it is incorrect in this context.
