Concept: A good composition is a written piece where all ideas are connected and flow smoothly. The most important quality is logical consistency, which makes the writing clear and easy to follow. Explanation: Composition means combining words and ideas to form a meaningful whole. A good composition must be logically consistent. This means each sentence and paragraph should connect naturally to the next. There should be no sudden jumps or contradictions. Logical consistency helps the reader understand the writer’s thoughts without confusion. Using too much passive voice, unnecessary phrases, or flowery language does not improve a composition. Instead, it often makes the writing unclear or artificial. Therefore, the key quality is maintaining logical consistency, not using fancy words or complex structures. Answer: Option A: maintaining logical consistency.
