Test your IQ with the question below: There is a mute who wants to buy a toothbrush. By imitating the action of brushing one's teeth he successfully expresses himself to the shopkeeper and the purchase is done. Now if there is a blind man who wishes to buy a pair of sunglasses, how should he express himself? Think about it first before scrolling down for the answer... He just has to open his mouth and ask, so simple. If you got this wrong please - do not pass go, just go dig a hole and hide.
