Explanation:

- The passage discusses imagination and its capabilities, emphasizing its role in invention, innovation, and understanding others.

- Blank (5) relates to experiences we have not shared with others, highlighting imagination’s empathic power.

- Option 1: Sporadically - Suggests occasionally shared experiences, which is not relevant here.

- Option 2: Never - Implies experiences entirely unshared, fitting the context of understanding unfamiliar situations.

- Option 3: Sooner - Implies a time-related concept, irrelevant to the context.

- Option 4: Hopefully - Suggests a future-focused intent, unrelated to shared experiences.

Option 2, "never," is indeed the correct choice, as it accurately conveys the idea of understanding those with whom we have not shared experiences.
