What is the major issue with sentence 11?

The major issue with sentence 11 being classified as a run-on sentence indicates that it contains two or more independent clauses that are improperly connected without appropriate punctuation or conjunction. In English grammar, a run-on sentence occurs when clauses are linked in a way that causes confusion or lack of clarity about where one idea ends and another begins.

When a sentence is a run-on, readers may struggle to follow the writer's intended meaning because the separate ideas are not distinguished clearly. Correcting a run-on could involve using a period to separate the clauses into distinct sentences, or utilizing commas along with conjunctions to connect them properly, allowing for clearer communication of the ideas expressed.

Identifying run-on sentences helps reinforce the importance of sentence structure in writing, ensuring that ideas are conveyed effectively and that the writing adheres to standard conventions of grammar.
