Which quality is often attributed to a nimble mind?

A nimble mind is characterized by quickness, agility, and the ability to think and understand ideas rapidly. When someone has a nimble mind, they can easily grasp complex concepts, respond swiftly to challenges, and adapt their thoughts in various situations. This quality is essential for problem-solving, creativity, and effective communication.

In contrast, clumsiness, slow-wittedness, and indifference suggest a lack of mental agility or responsiveness. Clumsiness implies a physical awkwardness rather than mental sharpness, slow-wittedness indicates a sluggish or dull intellect, and indifference reflects a lack of interest or reaction, which does not align with the idea of a nimble and engaged mind. Therefore, quickness is the only choice that appropriately reflects the essence of mental agility associated with a nimble mind.
