<span>What is missing from this sentence is A. a predicate. We have the subject - as a matter of fact, the whole sentence is a subject that needs to be finished somehow - and the way to finish this phrase is by adding a predicate in order to make it a sentence. A group of words where there is no predicate is just a phrase - it is not a sentence. </span>
"I take the theme of 'Eveline' to be one of Joyce's key preoccupations, the idea of paralysis, our inability to break out of situations that have become home for us, even when those situations are unpleasant or worse. Most of the story is taken up with Eveline's reflections and her attempts to balance her decision"
I hope this was helpful!
