Question 15.

Option A: This is incorrect because it overgeneralizes the ideas presented in the passage. The passage does not state that all humans are musicians or capable of musicking, only that making music is a universal aspect of the human experience and that the capacity for musicking is innate in humans.

Option B: The passage does state that musicking is a form of expression, but there is no discussion supporting the claim "musicking is not language-like." Thus, we can eliminate this choice.

Option C: The passage states - {"...if we look back 20,000 years, a small portion of this long period, we reach the lives of humans whose musical capacities were probably little different from our own..."} This suggests that the musical capacities of humans 20,000 years ago were not significantly different from those of humans today.

Option D: This is not supported by the passage. The passage does not state that all musical work is located in the overlap between linguistic capacity and music production. In fact, the passage states that "most of these capacities overlap with nonmusical ones, though a few may be distinct and dedicated to musical perception and production," suggesting that there are some capacities specifically dedicated to musical perception and production that do not overlap with nonmusical ones.

Hence, the correct answer is Option C.
