Answer:
We can deduce the meaning of the prefix re- is "again".
Explanation:
If someone reenacts something, that means they do it again, by acting. For instance, a group of actors may reenact a historical battle. That means they are performing it again. The same goes for repacking something or reregistering something. That means you are packing again or registering again. What all three words have in common is the prefix re-, which leads us to deduce the prefix means "again".
