Answer: Air exerts pressure. Wind blowing in high speed may break or displace many things. If holes are made in hanging banners andhoardings, then air can pass through these holes, which reduces the air pressure exerted on the banners and hoardings. That is why holes are made in hanging banners and hoardings.
