Explanation:

The word "imperceptible" has the root "percept" which relates to perception. "Perceptivity" likely builds on this root. Looking at the examples:

• In "The perceptivity of the detective to not give up helped solve the case", it's not just about facts (so "knowing facts or trivia" is less likely).
• In "He demonstrated an exceptional perceptivity for music theory", it implies understanding or insight rather than just a general resolve (as "resolve" is more about determination).

Answer:

having understanding or insight
