Answer: I would contend that the right answer is the B) It would emphasize to the listener how different drums and other musical instruments sounded like in the past.
Explanation: Just to elaborate a little on the answer, it can be added that option D should be discarded, since it is clearly irrelevant, particularly because the slit drum from Central Africa cannot be compared to a modern musical instrument, and the goal is not to help the listener replicate the sound, but experience it. In addition, option A can also be discarded, since an audio version should enhance the listener's experience while he or she is in front of the object, not announce what he or she will experience next. Finally, since the excerpt does not mention anything about the emotions that people in the past —the powerful chief and his retinue—felt while listening to the drums, I believe that the audio version is not primarily meant to elicit the same emotions in the listener. The audio version would, therefore, stress how different musical instruments sounded like in the past, since the label is specifically describing how the design of the drum had the potential to produce various tones and pitches.
