Which of the following is NOT a characteristic of concrete details?

Concrete details are specific pieces of information that are tangible and can be observed or measured. They help to create a clear mental picture for the reader and often involve sensory descriptions—what can be seen, heard, touched, tasted, or smelled. Specificity allows for a precise understanding, while descriptiveness enriches the narrative or argument by bringing the details to life.

The option referring to abstractness does not align with the characteristics of concrete details. Abstractness involves general ideas or concepts that lack physical substance and are often subjective, making them less effective in painting a vivid picture for the reader. Therefore, it is the presence of tangible elements like actuality and descriptiveness that defines concrete details, contrasting sharply with the notion of abstractness.
