Question

select the dependent clause. before you pour concrete for a new driveway, you should lay down steel bars for structural reinforcement.

Explanation:

An independent clause can stand alone as a complete sentence. In the given sentence, "you should lay down steel bars for structural reinforcement" can stand alone with a subject "you" and a predicate "should lay down steel bars for structural reinforcement". The clause "Before you pour concrete for a new driveway" is a dependent clause as it starts with the subordinating conjunction "Before" and cannot stand alone.

Answer:

you should lay down steel bars for structural reinforcement
