C. READING Read the passage and choose one correct answer for each question. The nuclear family, consisting of a mother, father, and their children may be more an American ideal than an American reality. Of course, the so-called traditional American family was always more varied than we had been led to believe, reflecting the very different racial, ethnic, class, and religious customs among different American groups. The most recent government statistics reveal that only about one third of all current American families fit the traditional mold and another third consists of married couples who either have no children or have none still living at home. Of the final one third, about 20 percent of the total number of American households is single people, usually women over sixty-five years of age. A small percentage, about 3 percent of the total, consists of unmarried people who choose to live together; and the rest, about 7 percent, are single, usually divorced parents, with at least one child. 44) With what topic is the passage mainly concerned? A. the traditional American family B. The nuclear family. C. The ideal family. D. The current American family. 45) The writer implies that .
