Passage 2 Between 1833 and 1837, the publishers of a "penny press" proved that a low-priced paper, edited to interest ordinary people, could win what amounted to a mass circulation for the times and thereby attract an advertising volume that would make it independent. These were papers for the common citizen and were not tied to the interests of the business community, like the mercantile press, or dependent for financial support upon political party allegiance. It did not necessarily follow that all the penny papers would be superior in their handling of the news and opinion functions. But the door was open for some to make important journalistic advances. The first offerings of a penny paper tended to ’be highly sensational; human interest stories overshadowed important news, and crime and sex stories were written in full detail. But as the penny paper attracted readers from various social and economic brackets, its sensationalism was modified. The ordinary reader came to want a better product, too. popularized style of writing and presentation of news remained, but the penny paper became a respectable publication that offered significant information and editorial leadership. Once the first of the successful penny papers had shown the way, later ventures could enter the competition at the higher level of journalistic responsibility the pioneering paper, had reached. This was the pattern of American newspapers in the years following the founding of the New York Sun in 1833. The Sun, published by Benjamin Day, entered the lists against 11 other dailies. It was tiny in comparison; but it was bright and readable, and it preferred human interest features to important but dull political speech reports. It had a police reporter writing squibs of crime news in the style already proved successful by some other papers. And, most important, it sold for a penny, whereas its competitors sold for sir cents. By 1837 the Sun was printing 30,000 copies a day, which was more than the total of all 11 New York daily newspapers combined when the Sun first appeared. In those same four years James Gordon Bennett brought out his New York Herald (1835), and a trio of New York printers who were imitating Day’s success founded the Philadelphia Public Ledger (1836) and the Baltimore Sun (1837). The four penny sheets all became famed newspapers. This passage is probably taken from a book on ______.

At least since the Industrial Revolution, gender roles have been in a state of transition. As a result, cultural scripts about marriage have undergone change. One of the more obvious (46) has occurred in the roles that women (47) . Women have moved into the world of work and have become adept at meeting expectations in that arena, (48) maintaining their family roles of nurturing and creating a(n) (49) that is a haven for all family members. (50) many women experience strain from trying to "do it all," they often enjoy the increased (51) that can result from playing multiple roles. As women’s roles have changed, changing expectations about men’s roles have become more (52) . Many men are relinquishing their major responsibility (53) the family provider. Probably the most significant change in men’s roles, however, is in the emotional (54) of family life. Men are increasingly (55) to meet the emotional needs of their families, (56) their wives. In fact, expectations about the emotional domain of marriage have become more significant for marriage in general. Research on (57) marriage has changed over recent decades points to the increasing importance of the emotional side of the relationships and the importance of sharing in the "emotion work" (58) to nourish marriages and other family relationships. Men and women want to experience marriages that are interdependent,(59) both partners nurture each other, attend and respond to each other, and encourage and promote each other. We are thus seeing marriages in which men’s and women’s roles are becoming increasingly more (60) .
