when are commas normally used? select three options.\n□ after introductory phrases and clauses\n□ around restrictive phrases and clauses\n□ around nonrestrictive phrases and clauses\n□ before the conjunction joining independent clauses\n□ before the conjunction introducing a dependent clause
Answer
Brief Explanations:
- Introductory phrases/clauses set context, so commas follow them to separate from the main clause.
- Nonrestrictive phrases/clauses add extra, non-essential info; commas set them apart from the core sentence.
- When a coordinating conjunction joins two independent clauses (complete sentences), a comma precedes the conjunction.
- Restrictive phrases/clauses are essential to define the noun, so they do not use surrounding commas.
- A comma is not needed before a conjunction introducing a dependent clause that follows an independent clause.
Answer:
- after introductory phrases and clauses
- around nonrestrictive phrases and clauses
- before the conjunction joining independent clauses
