What does the term 'interminable' imply in discussions?

The term 'interminable' is used to describe something that seems to have no end or is excessively prolonged. It often carries a negative connotation, suggesting that the duration is tedious or frustrating, such as in the context of a conversation or a tedious task that feels like it goes on forever. This aligns perfectly with the choice indicating that it means "endless or prolonged," capturing the essence of the term and how it is typically used in discussions to express the feeling of time dragging on without conclusion. The other options do not fit the meaning of 'interminable.' For example, terms that suggest meaningfulness or efficiency—like "meaningful and purposeful," "short and efficient," and "simple and uncomplicated"—contradict the characteristic of being endlessly long or having an unbearable duration.
