Question

read the sentence. During the epidemic, early warnings circulated widely. which correctly analyzes each word’s part of speech in the sentence

Answer 1

I am not completely sure what you are asking. But here is my best shot.

During - time, it tells what is happening while

the - is a preposition

epidemic - what is happening (relates to the first question)

early - when it is happening

warnings - the noun/subject

widely - where it is going

This is a standard form of speech.
