Answer:
re-
Explanation:
"Pre" means before, so a prefix is placed before the root of a word, and it changes the meaning of the word.
In the word remodeling, it can be broken into 3 parts: re-, model, and -ing. When these 3 components are combined, it forms the word.
re- comes before model. Therefore, re- is the prefix.
model would be considered the root.
-ing comes after the root, so it would be considered the suffix.
The prefix is re-.
