What is the capacity of Gallery 6?

The capacity of Gallery 6 is indeed 15. This figure reflects the specific design and layout of the gallery, which is configured to ensure a comfortable and engaging viewing experience for visitors. Smaller galleries often have reduced capacities to maintain an intimate environment, enhance visitor interactions, and allow for proper spacing between exhibits.

In comparison, the other options suggest higher capacities that would not align with the intended atmosphere and operational considerations of such a space. Maintaining a lower capacity like 15 can also help with crowd management, safety protocols, and ensure that each visitor's experience is enriched rather than crowded. This specific capacity likely comes from planning and assessment tailored to the space's size and usage, illustrating the importance of thoughtful design in gallery settings.
