What characteristic is associated with "superficial" understanding?

A "superficial" understanding is characterized by a lack of depth and thoroughness. This term suggests that the knowledge held is only surface-level, meaning the individual might grasp basic concepts but fails to engage with more complex ideas or the underlying principles. This shallow understanding does not allow for critical thinking or deeper analysis, which are essential for a more profound grasp of a subject.

In contrast, the other choices imply a deeper level of comprehension or analytical ability, which are not descriptors of a superficial understanding. Comprehensive and profound knowledge indicates a substantial and detailed grasp of a topic, while being highly analytical suggests an ability to break down complex information and understand its intricacies. Lastly, an insightful and informed understanding reflects a deep awareness and thoughtful consideration of a subject, again contrasting with the notion of being superficial.
