[不定项选择题]One of the greatest contributions ofFreud is that he elaborated the structure of human psyche as "Id","Ego" and "Superego". "Ego" is the natural humanpsychological characteristic that changes everything in its way and makeseveryone a victim to undesirable consequences in their life. The pride andself-esteem if they are overrated in our mind will be shown in the form of Ego.The Human Ego conceals our "natural intellect" to create falseownership over every object. Here is an interesting story which couldillustrate the case.
Once there was a scientist who worked hardall through his life to make exact human physical body replicas of himself. Hemastered the art so perfectly that one could not easily tell the replica fromthe original. According to the natural process, the Angel Death knocked at hisdoor. The Angel Death felt puzzled by looking at the thirteen same persons.Obviously unable to recognize the original person, the Angel returned in vain.The scientist got the illusion that he can avoid death easily.
Nevertheless the Angel Death who has clearunderstanding of human life did not give up and came back with a trick Sheagain approached the scientist and was staring at the thirteen human figures.
Then she told the scientist, "You havemanaged everything correctly but you could not avoid a small flaw whilereproducing yourself′. The scientist hurriedly spoke out the small flaw that itwas impossible in his work. Then he was caught by Angel Death.
The Ego blinds us to hide reality, so wetend to make small mistakes though we are given greater skills and strength.Therefore each one of us has to be careful about our accomplishments andachievements so that we don′t make us blind toward this living world whereevery individual is presented upon with equal grace and strength. Thus we haveto decrease the feeling of "All is I" and increase the feeling of"I am nothing before All", which makes us proud of everything wehave.

A.To make the Angel Death feel confused.
B.To show his own skills to make replicas.
C.Not mentioned clearly in the passage.
D.To avoid the small flaws of hisoriginal.
