In a closed room with no visible windows or doors, Zephyr holds a lit candle. A strong breeze suddenly extinguishes the flame. Assuming there are no mechanical devices in the room, what can Zephyr infer about the room's structure? Provide a very brief response.
Zephyr can infer that there must be an opening or gap in the room's structure that allowed the wind to enter and extinguish the candle. Even though no windows or doors are visible, the presence of a breeze indicates that air is flowing into the room from somewhere, suggesting a hidden passage or an architectural feature not immediately apparent to Zephyr. The wind flow could be caused by factors like differences in air pressure or temperature between the inside of the room and the outside environment, leading to the air movement that blew out the candle.
