The use of simple words, short sentences, and narrow paragraphs will render your work product clear and concise. Pointed sentences composed of tight words will keep a grasp on the reader, allowing their minds to flow continuously through your written argument in a focused fashion.
A long sentence that goes on and on and moves from idea to idea with words and notions will surely lose the reader at midpoint and make that reader then have to go back and re-read the sentence more than once in order to understand what is being conveyed, thereby puzzling the reader and possibly making him or her lose interest in reading the rest of what you have written because the reader has forgotten what point the sentence is attempting to convey in the first place about long sentences.
