What characteristic best describes an efficient sentence?

An efficient sentence is best characterized as fluent. Fluency in a sentence refers to its smooth and natural flow, which enhances readability and understanding for the audience. A fluent sentence uses correct grammar, appropriate vocabulary, and cohesive structure that allows the reader to grasp the meaning without effort or confusion. This is vital in technical communication because clarity and ease of reading are essential for conveying complex information effectively.

While being informative, entertaining, or short are valuable attributes of a sentence, fluency encompasses the overall effectiveness of communication. An informative sentence might provide necessary details but could also be convoluted, making it hard to follow. Similarly, an entertaining sentence could sacrifice clarity for creativity, and a short sentence might omit essential information, leading to ambiguity. Thus, fluency stands out as the most comprehensive characteristic that underpins an efficient sentence, ensuring that the message is conveyed clearly and effectively.
