In modern society, the extreme refinement of the professional division of labor requires ordinary people to rely on the advice of experts in every professional field. Experts rely on their in-depth professional knowledge to provide guidance to people and build their own authority and public trust. However, it is also this authority and trust that brings corresponding responsibilities-experts must maintain a fair position when speaking, seek truth from facts, and earnestly verify that there is a piece of evidence to speak a piece of words, which can not be breached with impunity. We can forgive some unavoidable loopholes and shortcomings in the expert opinion, but we cannot condone the expert's responsibility to give up responsibility, nonsense, and confused audiovisual. What is the main emphasis of this text? ['People are not sages, and the opinions of experts are inevitable.', "Expert's right and wrong judgment and countermeasures play an extraordinary guiding role.", 'Some experts give up responsibility, make nonsense, confuse audiovisual.', 'Experts must maintain a fair position when speaking, be realistic.']
