Answer 2

Answer:

It is not a good idea to buy a house without ventilators because warm air is lighter than cold air hence warm air passes out of your home through ventilators. Accordingly, without ventilators, warm air will not pass out, and the house will remain warm. Holes in the banners and hoardings helps air to pass through it. Hence, banner can withstand the pressure of the air and remains intact.
