In a house with a red gate lives a man. Someone asked his wife if she wanted to kill the man or if she wanted that someone else killed him. This passage is based on the use of the passive voice: of which = of the house => of which the gate is red = the gate of the house is red the wife was asked = [someone] has asked the wife to have him killed = to have him killed [by someone else]
