Which of the following best defines "contiguous"?

The term "contiguous" refers to things that are very close or connected in space or time. This definition emphasizes the idea of proximity and continuity without anything intervening. For example, in geography, contiguous land areas are those that touch each other directly, such as states in the United States that share a common border. In a temporal context, events that are contiguous occur one after the other without interruption, suggesting a seamless flow.

The other options highlight different concepts that do not align with the core meaning of "contiguous." Strikingly different experiences, occurrences at varied intervals, or items having no relationship are all distinct ideas that do not convey the sense of closeness or connection inherent in the meaning of "contiguous."
