so i wanna share with you the past year question....
let you guys who wondering how is a level standard a try....

Undoubtedly,people are always looking for higher levels of affluence and for evermore impressive demonstrations of human power. To this end,experts work for greater efficiency in the organisation of society. They have succeeded to such an extent that nothing is any longer simple or readily apparent to th non-technical man. The organisation of science is now the province of the experts-or those who can employ them. In such a society, the ordinary citizen, confronted by bewildering magnitude and complexity, finds it neccesary to defer on all matters to those who know better. It would be a violation of reason to do otherwise.

Which of the following best expresses the main conclusion of the argument above?

A. Today's society is too complex to be understood by any one person.

B. The chief aim of society is to maintain efficient prduction.

C. People in today's society expect an ever- increasing level of affluence and human power.

D. Ordinary citizens should make a greater effort to become acquainted with technical matters.

E. People without technical knowledge have no effective voice in deciding how society is run.
