Writing requires a lot of attention and knowledge, not only of grammar, but also of the coherence of the sentences within a text and the structure that these sentences form, being able to transmit an understandable message to the reader. Effective and efficient writing should refrain from Run-on sentences that leave writing completely without coherence and cohesion because it does not link one sentence to another in a fluid and correct way, leaving the text disorganized and making the reading uncomfortable and inconclusive. Efficient writing must also refrain from fragments sentences that are incomplete sentences, which do not have the capacity to conclude a thought and transmit a tangible message to the reader.
