Question: Write a multi-choice question for the following article, with the given choices and answer: Article: It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible.Everybody knows that the nicest men would become fierce tigers behind the wheel.It is all right to have a tiger in a cage, but to have one in the driver's seat is another matter altogether. Road politeness is not only good manners, but good sense too.It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving.On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting.A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and calm so necessary in modern traffic condition.But such behaviors of politeness are by no means enough.Many drivers nowadays don't even seem able to recognize politeness when they see it. However, misplaced politeness can also be dangerous.Typical examples are the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may be not able to stop in time.The same goes for encouraging old ladies to cross the road wherever and whenever they want to.It always amazes me that the highways are not covered with the dead bodies of these grannies .
