What does 'extemporaneous' suggest about the quality of work done?

The term 'extemporaneous' refers to something that is done without prior preparation or planning, often in a spontaneous or impromptu manner. When a work or act is described as extemporaneous, it implies that it has a certain immediacy and is typically characterized by a natural flow, rather than being meticulously thought out or pre-scripted. This quality can lead to a more authentic or candid expression, but it may also suggest a level of unpredictability as it is created on-the-spot.

The connection of 'extemporaneous' to spontaneity sets it apart from the other choices, which imply different approaches. For example, work that is carefully planned, rehearsed, or intentionally scripted suggests deliberate preparation and intention, contrasting with the inherent unpredictability and fresh nature of something that is extemporaneous.
