Question

identify the reason for the comma in the following sentence.
the essay, class, will be due on thursday.
○ direct address
○ compound sentence
○ paired words
○ introductory words

Explanation:

The word "class" is a direct address to the audience being spoken to, and commas are used to set off this direct address from the main clause of the sentence. A compound sentence requires two independent clauses joined by a conjunction, which this sentence does not have. Paired words refer to correlative conjunctions or similar paired structures, which are not present here. Introductory words appear at the start of a sentence, not in the middle as "class" does.

Answer:

direct address
