A quick questions about the structure of a sentence
Here is the sentence that confused me.....
Over the last couple years, a plethora of research has been pouring in that makes connections between Facebook and narcissism.
I'm wondering which part of the sentence is the subject and which part is the predicate?
This is what i think
Subject : a plethora of research
predicate: has been pouring in that makes connections between Facebook and narcissis.
the next problem is what the word "that" in the sentence refers to ???
Thank you you, guys
