    Whales are the largest animals in the world, and the gentlest creatures we know. Although the whale is very huge, it is not hindered at all by its size when it is in the water. Whales have tails that end like flippers. With just a gentle flick, it can propel itself forward. The skin of a whale is so smooth that it does not create any friction that can slow the whale down. A whale’s breathing hole is located on the top of its head, so it can breathe without having to completely push its head out of the water. Whales are protected from the cold seawater by body fat that is called blubber.

    Whales live in the ocean but, in terms of behaviors, they are more similar to humans than fish. They live in family groups and they even travel in groups when they have to migrate from cooler to warmer waters. The young stay with their parents for as long as fifteen years. Whales are known not to desert the ill or injured members; instead, they cradle them.

    When whales are in danger, there are people who go to great lengths to help them. One such case occurred in 1988, when three young whales were trapped in the sea. It was close to winter and the sea had begun to freeze over. Whales are mammals that require oxygen from the air, so the frozen ice was a great danger to them. All they had then was a tiny hole in the ice for them to breathe through. Volunteers from all over soon turned up to help these creatures. They cut holes in the ice to provide more breathing holes for the whales. These holes would also serve as guides for the whales so that they could swim to warmer waters.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 44 to 50. 

    Nuclear family, also called elementary family, in sociology and anthropology, is a group of people who are united by ties of partnership and parenthood and consisting of a pair of adults and their socially recognized children. Typically, but not always, the adults in a nuclear family are married. Although such couples are most often a man and a woman, the definition of the nuclear family has expanded with the advent of same-sex marriage. Children in a nuclear family may be the couple’s biological or adopted offspring.

    Thus defined, the nuclear family was once widely held to be the most basic and universal form of social organization. Anthropological research, however, has illuminated so much variability of this form that it is safer to assume that what is universal is a “nuclear family complex” in which the roles of husband, wife, mother, father, son, daughter, brother, and sister are embodied by people whose biological relationships do not necessarily conform to the Western definitions of these terms. In matrilineal societies, for example, a child may be the responsibility not of his biological genitor but of his mother’s brother, who fulfills the roles typical of Western fatherhood.

    Closely related in form to the predominant nuclear-family unit are the conjugal family and the consanguineal family. As its name implies, the conjugal family is knit together primarily by the marriage tie and consists of mother, father, their children, and some close relatives. The consanguineal family, on the other hand, typically groups itself around a unlineal descent group known as a lineage, a form that reckons kinship through either the father’s or the mother’s line but not both. Whether a culture is patrilineal or matrilineal, a consanguineal family comprises lineage relatives and consists of parents, their children, and their children’s children. Rules regarding lineage exogamy are common in these groups; within a given community, marriages thus create cross-cutting social and political ties between lineages.

    The stability of the conjugal family depends on the quality of the marriage of the husband and wife, a relationship that is more emphasized in the kinds of industrialized, highly mobile societies that frequently demand that people reside away from their kin groups. The consanguineal family derives its stability from its corporate nature and its permanence, as its relationships emphasize the perpetuation of the line.
