Science is the search for truth. In the process of searching for truth, people's understanding of objective laws must go through a difficult and torturous process. There are often such situations: due to different research perspectives, differences in the mastery of data, and different methods of recognition, there will be the situation of horizontal ridges and peaks, different heights and distances, caused academic debates. Therefore, active scientists regard the opposition as a great help to themselves, and treat their own criticism as Precious friendship. As Li Siguang said: "Nothing can inspire me more than a frank criticism of my thesis. " Goethe also said: "What we agree with keeps us in peace. What we object to Only by making our thoughts productive. "This is because the opinions of approval are not necessarily correct, and the opinions of opposition are not necessarily wrong. Taking a step back, even the wrong opposition is good for our own scientific research. Which one of the following statements about the text is correct? ['Science is seeking the truth.', "People's understanding of objective laws must go through a difficult and tortuous process.", 'Proactive scientists understand the importance of objections.', 'Consensus may not be correct, and opposition may not be wrong.']
