Question

grammar and punctuation unit test
which option always requires a comma before the conjunction? (1 point)
○ compound sentence
○ appositive
○ long introductory element
○ items in a series

Explanation:

In grammar, a compound sentence consists of two independent clauses joined by a coordinating conjunction (like and, but, or). By rule, a comma is always required before the conjunction in a compound sentence. For an appositive, commas are used but not always before the conjunction - related part. A long introductory element uses a comma after it, not before a conjunction. Items in a series use commas between items, not related to a conjunction before it.

Answer:

A. compound sentence
