Deduce the meaning of the prefixes based on the given words; Reeneactment
Repack
Reregister​

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".

the excerpt from chapter 2 of "animal farm", by george orwell that is an example of foreshadowing is "these three (snowball, napoleon, and squealer) had elaborated old major's teachings into a complete system of thought to which they gave the name of animalism." animal farm is an allegory of how czarist russia developed into communist russia with all its corruption. old major's teachings represent marx's theories turned into communism, animalism, by the three pigs. this foreshadows the oppression and corruption that will follow this revolt.
