Ok, here is what we have.
First of all start with what we know.
What does prediction mean?
A prediction is what someone thinks will happen. A prediction is a forecast, but not only about the weather. Pre means “before” and diction has to do with talking. So a prediction is a statement about the future. It's a guess, sometimes based on facts or evidence, but not always.

Now, since that is out the way. Lets start answering now that you know the key idea.
The prediction of a sentence indicates a guess but not just any guess a highly education guess gathered by information provided.
Hope this helps.
I never did college work before.
