A、Greeks. B、Arabians. C、Indians. D、Chinese. BAt one time，who had the custom of kissing the hand of their superior? 细节题。短文中提到Amon

Today it is perfectly natural for us to shake hands when we greet someone, or say goodbye. But like so many other things we do without thinking such actions at one time probably symbolized something else.
For example, in primitive life the hand was probably a symbol of power and strength. The hand was used to fight enemies, kill animals and make spears and implements. So when the hand was extended to someone, it could have represented good will, since it showed that the person was not armed or ready to fight.
We know that the hand was an important symbol in early religion, probably as a mark of power. The Greeks prayed to their gods with raised hands. Presenting hands palm to palm was at one time the way an inferior person paid respect to a superior.
Among the Arabs, it was customary at one time to kiss the hand of a superior. Later on, polite Arabs began to resist the efforts of people to kiss their hands, and some- times they would end up clasping hands as each tried to prevent the other from showing this mark of "inferiority".
The early Greeks held out the right hand when they wished to indicate friendship to a stranger. The hand and what was done with it have been full of meaning to people down through the ages. And while we shake hands, we are really carrying on a custom that has been handed down to us from ancient times.
