Forgive me if my use of terminology isn't quite right...
I'm editing this sentence:
This is a serious problem that ranges from elementary school teachers to adjunct professors such as here, and deserves far more attention than it receives.
The segment "that ranges from teachers to professors such as here" plays the role of what I believe is an essential clause. From what I've read, you generally use no comma after an essential clause, as in this example:
The man [who ordered the pizza] tried to pay with a foreign currency.
versus with a nonessential clause:
Mr Brown, [who ordered the pizza], tried to pay with a foreign currency.
Which ARE placed between commas. So, my question is: CAN you use a comma after an essential clause, as in the my above sentence? Or am I required to remove the comma?
The reason I fell into this rabbit hole at all was I at first thought the second clause was a fragment and added a subject, but then I realized it didn't SOUND bad the way it had been... and got super curious!
Let me know if I'm mistaken at all, and thanks in advance.
Actually, now that I think of it, I'm certain this question no longer has to do with restrictive vs non-restrictive clauses, and rather has to do with the grammar of this sentence:
This is a serious problem, and deserves far more attention than it receives.
Assuming this sentence is grammatically correct, I'm now more confident that the answer I've marked is the correct explanation.
