In a room, there is a table in the center with a single lightbulb hanging directly above it. Zephyr is standing on one side of the table and Octavia is standing on the opposite side. A tall opaque vase is placed in the center of the table. Given that the light is the only source of illumination in the room, can Zephyr see Octavia's face?

Provide a very brief response.
Zephyr cannot see Octavia's face because the opaque vase is blocking the line of sight between them. The light from the single bulb above casts a shadow of the vase onto the table and potentially onto the surrounding area, including where Octavia would be standing. Since the vase is tall enough to obstruct Zephyr's view, the light cannot reach Octavia's face directly from Zephyr's perspective, thus it remains hidden behind the vase's shadow and the vase itself.
