Task: Identify Run-on Sentences


The task is to determine whether each sentence provided is a run-on sentence or not. A run-on sentence occurs when two or more independent clauses (complete sentences) are joined without proper punctuation or conjunctions.

#### Steps to Solve:
1. Identify Independent Clauses: An independent clause can stand alone as a complete sentence. It has a subject and a predicate.
2. Check for Proper Punctuation: Run-on sentences often lack necessary punctuation (like periods, semicolons, or colons) or coordinating conjunctions (e.g., "and," "but," "or") to separate the clauses properly.
3. Mark the Sentence: If the sentence is a run-on, write "RO" on the line. If it is not a run-on, write "I" (for "independent").
