Answer:
Your answer would be that the choices that correct the run-on sentence are the following ones:
- The dog loves liver treats. It wags its tail every time it smells treats
- The dog loves liver treats, and it wags its tail every time it smells them
Step-by-step explanation:
A run-on sentence occurs when two independent clauses are not joined correctly. There are two types of run-on sentences: fused sentences and comma splices. The first ones occur when independent clauses run together with no punctuation marks or coordinating conjunctions to separate them. Comma splices occur when two or more independent clauses are joined only by a comma.
In this case, this run-on sentence is a fused sentence as it neither contains punctuation marks nor coordinating conjunctions. You can fix this by inserting a comma and a coordinating conjunction, as one of the choices shows; or by introducing a semicolon to separte the clauses. In addition to this, you could separate the clauses and turn them into two independent sentences by introducing a period (the dog loves liver treats. It wags...)
