Ways to tell them apart:
Unprecedented has an element of novelty or being the first of its kind, while rare implies something that doesn't occur often but may have occurred in the past.
Think of unprecedented as breaking new ground, something youve never seen before, whereas rare' is about scarcity, something that exists but in limited quantities.
Use unprecedented when referring to something that is completely new and unparalleled, while rare should be used when talking about exceptions or unusual occurrences that are not new.
