Passage Four
Equal pay for equal work is a phrase used by the American women who feel that they are looked down upon by society. They say it is not right for women to be paid less than men for the same work.
People who hold the opposite opinion (mainly men) have an answer to this. They say that men have more responsibility than women; a married man is expected to earn money to support his family and to make the important decision, and therefore it is right for men to be paid more. There are some people who hold even stronger opinion than this and are against married women working at all. When wives go out to work, they say, the home and children are given no attention to. If women are encouraged by equal pay to take full time job, they will be unable to do the things. Women are best at making a comfortable home and bringing up children. They will have to give up their present position in society.
This is exactly what they want to give up, the women
A. women can't do what men can
B. men can earn money more easily than women
C. men's responsibilities are different from women's
D. men have to work much harder than women
