Many Americans regard the jury system as a concrete expression of crucial democratic values, including the principles that all citizens who meet minimal qualifications of age and literacy are equally competent to serve on juries; that jurors should be selected randomly from a representative cross section of the community; that no citizen should be denied the right to serve on a jury on account of race, religion, sex, or national origin; that defendants are entitled to trial by their peers; and that verdicts should represent the conscience of the community and not just the letter of the taw. The jury is also said to be the best surviving example of direct rather than representative democracy. In a direct democracy, citizens take turns governing themselves, rather than electing representatives to govern for them.But as recently as in 1968, jury selection procedures conflicted with these democratic ideals. In some states, for example, jury duty was limited to persons of supposedly superior intelligence, education, and moral character. Although the Supreme Court of the United States had prohibited intentional racial discrimination in jury selection as early as the 1880 case of Strauder v. West Virginia, the practice of selecting so-called elite or blue-ribbon juries provided a convenient way around this and other antidiscrimination laws.The system also failed to regularly include women on juries until the mid-20th century. Although women first served on state juries in Utah in 1898, it was not until the 1940s that a majority of states made women eligible for jury duty. Even then several states automatically exempted women from jury duty unless they personally asked to have their names included on the jury list. This practice was justified by the claim that women were needed at home, and it kept juries unrepresentative of women through the 1960s.In 1968, the Congress of the United States passed the Jury Selection and Service Act, ushering in a new era of democratic reforms for the jury. This law abolished special educational requirements for federal jurors and required them to be selected at random from a cross section of the entire community. In the landmark 1975 decision Taylor v. Louisiana, the Supreme Court extended the requirement that juries be representative of all parts of the community to the state level. The Taylor decision also declared sex discrimination in jury selection to be unconstitutional and ordered states to use the same procedures for selecting male and female jurors. After the Jury Selection and Service Act was passed, ______

A. sex discrimination in jury selection was unconstitutional and had to be abolished
B. educational requirements became less rigid in the selection of federal jurors
C. jurors at the state level ought to be representative of the entire community
D. states ought to conform to the federal court in reforming the jury system

I was addressing a small gathering in a suburban Virginia living room—a women"s group that had invited men to join them. Throughout the evening one man had been particularly talkative frequently offering ideas and anecdotes while his wife sat silently beside him on the couch. Toward the end of the evening I commented that women frequently complain that their husbands don"t talk to them. This man quickly nodded in agreement. He gestured toward his wife and said, "She"s the talker in our family." The room burst into laughter; the man looked puzzled and hurt. "It"s true," he explained. "When I come home from work I have nothing to say. If she didn"t keep the conversation going, we"d spend the whole evening in silence."This episode crystallizes the irony that although American men tend to talk more than women in public situations, they often talk less at home. And this pattern is wreaking havoc with marriage.The pattern was observed by political scientist Andrew Hacker in the late 1970s. Sociologist Catherine Kohler Riessman reports in her new book Divorce Talk that most of the women she interviewed—but only a few of the men—gave lack of communication as the reason for their divorces. Given the current divorce rate of nearly 50 percent, that amounts to millions of cases in the United States every year—a virtual epidemic of failed conversation.In my own research, complaints from women about their husbands most often focused not on tangible inequities such as having given up the chance for a career to accompany a husband to his, or doing far more than their share of daily life-support work like cleaning, cooking and social arrangements. Instead, they focused on communication: "He doesn"t listen to me." "He doesn"t talk to me." I found, as Hacker observed years before, that most wives want their husbands to be first and foremost conversational partners, but few husbands share this expectation of their wives.In short, the image that best represents the current crisis is the stereotypical cartoon scene of a man sitting at the breakfast table with a newspaper held up in front of his face, while a woman glares at the back of it, wanting to talk. Which of the following can best summarize the main idea of this text

A. The moral decaying deserves more research by sociologists
B. Marriage break-up stems from sex inequalities
C. Husband and wife have different expectations from their marriage
D. Conversational patterns between man and wife are different
