Detailed Solution

If a strong wind blows along the corridor, the curtain will get pushed outside the room.
High-Speed winds in the corridor create a low-pressure zone, whereas the pressure inside the room remains equal to the atmospheric pressure, which is more than the pressure in the corridor. So the air from the room will flow towards the corridor to balance the pressure difference. So the curtains will get pushed outside the room due to the inside air pressure.
