In a perfectly free and open market economy, the type of employer—government or private—should have little or no impact on the earnings differentials between women and men. However, if there is discrimination against one sex, it is unlikely that the degree of discrimination by government and private employers will be the same. Differences in the degree of discrimination would result in earnings differentials associated with the type of employer. Given the nature of government and private employers, it seems most likely that discrimination by private employers would be greater. Thus, one would expect that, if women are being discriminated against, government employment would have a positive effect on women’s earnings as compared with their earnings from private employment. The results of a study by Fuchs support this assumption. Fuchs’s results suggest that the earnings of women in an industry composed entirely of government employees
A. Both private employers and government employers discriminate, with equal effects on women's earnings.
B. If private employers and government employers discriminate, the discrimination by private employers has a greater effect on women's earnings.
C. Private employers discriminated it is possible that government employers discriminate.
D. Private employers discriminate; government employers do not discriminate.

[填空题]To the curious and the courageous, the sea still presents the challenge of the unknown, for ignorance is still the distinguishing characteristic of man’s relation to the sea. But now, more than ever, necessity urges us onward in our exploration of the sea. We now have submarines capable of staying under water for many months holding missiles capable of destruction many times greater than those used in World War Ⅱ. For strategic reasons, therefore, we need urgently to learn more about the ocean bottom. Quite apart from the threat of war, another necessity presses us to learn to master the sea. That necessity is basic to life itself: food. The lives of 2/3 of the world’s people are wholly dictated by that basic necessity; they are oppressed by hunger and by the weakness and disease which hunger generates. Out of the sea we can extract food to relieve the hunger of these millions of people and give dignity to their lives. We must tuna to the sea, because the bounty of the land has limits.
