Senator Clinton has been complaining about "there is a gap between men's and women's wages". The reality is that men's average salary is $ 1 per hour, while women's are only 78.5 cents. Some politicians have pointed out that the gap between men's and women's wages is due to patriarchalism. Entrepreneurs are willing to pay more for men. Which of the following statements is true, the argument that best refutes the above argument? ? ['The average wage is calculated on the basis of all working and unemployed persons who have the ability to work, and the number of women who choose to take care of their homes far exceeds that of men.', 'Based on cost considerations, entrepreneurs should select women over men for lower pay in the same job than men.', 'In the same job, women entrepreneurs also intend to pay more for men.', 'There is no difference in the level of work between men and women in mental work.']
