Students of United States history, seeking to identify the circumstances that encouraged the emergence of feminist movements, have thoroughly investigated the mid-nineteenth-century American economic and social conditions that affected the status of women. These historians, however, have analyzed less fully the development of specifically feminist ideas and activities during the same period. Furthermore, the ideological origins of feminism in the United States have been obscured because, even when historians did take into account those feminist ideas and activities occurring within the United States, they failed to recognize that feminism was then a truly international movement actually centered in Europe. American feminist activists who have been described as "solitary" and "individual theorists" were in reality connected to a movement — utopian socialism — which was already popularizing feminist ideas in Europe during the two decades that culminated in the first women’s rights conference held at Seneca Falls, New York, in 180o8. Thus, a complete understanding of the origins and development of nineteenth-century feminism in the United States requires that the geographical focus be widened to include Europe and that the detailed study already made of social conditions be expanded to include the ideological development of feminism. The earliest and most popular of the utopian socialists were the Saint-Simonians. The specifically feminist part of Saint-Simonianism has, however, been less studied than the group’s contribution to early socialism. This is regrettable on two counts. By 1832 feminism was the central concern of Saint- Simonianism and entirely absorbed its adherents’ energy. Hence, by ignoring its feminism, European historians have misunderstood Saint- Simonianism. Moreover, since many feminist ideas can be traced to Saint- Simonianism, European historians’ appreciation of later feminism in France and the United States remained limited. Saint-Simon’s followers, many of whom were women, based their feminism on an interpretation of his project to reorganize the globe by replacing brute force with the rule of spiritual powers. The new world order would be ruled together by a male, to represent reflection, and a female, to represent sentiment. This complementarity reflects the fact that, while the Saint-Simonians did not reject the belief that there were innate differences between men and women, they nevertheless foresaw an equally important social and political role for both sexes in their Utopia. Only a few Saint-Simonians opposed a definition of sexual equality based on gender distinction. This minority believed that individuals of both sexes were born similar in capacity and character, and they ascribed male-female differences to socialization and education. The envisioned result of both currents of thought, however, was that women would enter public life in the new age and that sexual equality would reward men as well as women with an improved way of life. According to the passage, the society envisioned by most Saint-Simonians would be one in which______.

A. women could obtain superior rights
B. women played a vital role in politics
C. the two genders competed with each other
D. the two genders had equal status

We know that he was baptized on April 26, 1564, so that somewhere between April 20 and April 23, four hundred years ago, was born an Englishman who possessed what was probably the greatest brain ever encased in a human skull. William Shakespeare’s work has been performed without interruption for some three hundred and fifty years everywhere in the world. Scholars and students in every land know his name and study his work as naturally as they study their holy books — the Gospels, the Torah, the Koran, and the others. For centuries clergymen have spoken Shakespeare’s words from their pulpits; lawyers have used his sentences in addressing juries; doctors, botanists, agronomists, bankers, seamen, musicians, and, of course, actors, painters, poets, editors, and novelists have used words of Shakespeare for knowledge, for pleasure, for experience, for ideas and for inspiration. It is hard to exaggerate the debt that mankind owes. Shakespeare’s greatness lies in the fact that there is nothing within the range of human thought that he did not touch. Somewhere in his writings, you will find a full-length portrait of yourself, of your father, of your mother, and indeed of every one of your descendants yet unborn. The most singular fact connected with William Shakespeare is that there is no direct mention in his works of any of his contemporaries. It was as though he knew he was writing for the audiences of 1964 as well as for the audiences of each of those three hundred and fifty years since his plays were produced. On his way to the Globe Theater he could see the high masts of the Golden Hind in which Sir Francis Drake had circumnavigated the globe. He lived in the time of the destruction of the Spanish Armada, the era in which Elizabeth I opened the door to Britain’s age of Glorlana, and he must have heard of Christendom’s great victory at Lepanto against the Turks which forever insured that Europe would be Christian. Shakespeare’s era was as momentous as our own. Galileo was born in 1564, the same year in which Shakespeare was born, and only a few years before John Calvin laid the foundation for a great new fellowship in Christianity. And yet Shakespeare in the midst of these great events, only seventy years after the discovery of America, did not mention an explorer or a general or a monarch or a philosopher. The magic of Shakespeare is that, like Socrates, he was looking for the ethical questions, not for answers. That is why there are as many biographies of a purely invented man Hamlet, as there are of Napoleon, Abraham Lincoln, or Franklin D. Roosevelt. We are not sure of many things in this life except that the past has its uses and we know from the history of human experience that certain values will endure as long as there is breath of life on his planet. Among them are the ethics of the Hebrews who wrote the Decalogue, the Psalms, and the Gospels of the Holy Bible, and the marble of the Greeks, the laws of Romans, and the works of William Shakespeare, There are other values which may last through all the ages of man — Britain’s Magna Carta, France’s Rights of Man, and America’s Constitution. We hope so, but we are not yet sure. We are sure of Shakespeare. Ben Johnson was a harsh critic of Shakespeare during his lifetime. They were contemporaries and competitors. Johnson, a great dramatist, did not like it when his play Cataline had a short mn and was replaced by Shakespeare’s Julius Caesar, which had a long run. Yet when Shakespeare died, Johnson was moved to a eulogy which he called "Will Shakespeare": Triumph my Britain. Thou has one to show. To whom all scenes of Europe Homage owe. He was not of an age, but for all time. The author mentioned the Holy Bible and the laws of Romans probably to______.

A. summarize great works carrying everlasting human values
B. demonstrate the importance of ethical questions
C. illustrate Shakespeare’s works are of equal importance
D. compare Shakespeare’s works with them
