Answer:
One of the clearest themes found in The Story of an Hour is the theme of freedom. Once the grief of finding out her husband died passes over her, Louise begins to realize that with his passing she has the freedom to live her own life. You can see the moment this realization hits as she whispers, “free, free, free.”
1) Find the object of the preposition.
2) Ask yourself which other word in the sentence is related to this noun or pronoun by the preposition.
1) Prefix "a-" means "without, not". The meaning of the word "apathetic" is "without emotion or feeling";
2) In the word "analgesic", prefix "a-" denotes the process of removing or eliminating something. So, "analgesic" means "a medicine to remove pain";
3) Prefix "ex-" has the meaning "out". That is why, the word "expulsion" is defined as "to drive out";
4) Prefix "endo-" means "inside, within". Consequently, "endodermis" is the name of the inner layer of skin.
