The weather is a national obsession in Britain, perhaps because it is so changeable. It's the national talking point, and most people watch at least one daily weather forecast. Most of the viewers imagine that the presenter does little more than arrive at the studio a few minutes before the broadcast, read the weather, and then go home. 

In fact, this image is far from the truth. The two-minute bulletin which we all rely on when we need to know tomorrow's weather is the result of a hard day's work by the presenter, who is actually a highly-qualified meteorologist.

Every morning, after a weather forecaster arrives at the TV studios, his/her first task of the day is to collect the latest data from the National Meteorological Office. The information is very detailed and includes predictions, satellite and radar pictures, as well as more technical data. After gathering all the relevant material from this office, the forecaster has to translate the scientific terminology and maps into images and words which viewers can easily understand. The final broadcast is then carefully planned. The presenter decides what to say and in what order to say it. Next a “story board” is drawn up which lays out the script word for word.     

The time allocated for each broadcast can also alter. This is because the weather report is screened after the news, which can vary in length. The weather forecaster doesn't always know how much time is available, which means that he/she has to be thoroughly prepared so that the material can be adapted to the time available.

What makes weather forecasting more complicated is that it has to be a live broadcast and cannot be pre-recorded. Live shows are very nerve-racking for the presenter because almost anything can go wrong. Perhaps the most worrying aspect for every weather forecaster is getting the following day's predictions wrong. Unfortunately for them, this is not an unusual occurrence; the weather is not always possible to predict accurately.

These days, a weather forecaster's job is even more complicated because they are relied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include the pollen count for hay fever sufferers. Some also include reports on ultraviolet radiation intensity to help people avoid sunburn. The job of a weather forecaster is certainly far more sophisticated than just pointing at a map and describing weather conditions. It's a job for professionals who can cope with stressful and challenging conditions.

Weather forecasters have to know the material well because _____.

A. the forecast may be incorporated into the news broadcast

B. they sometimes need to change it to meet the time limitation

C. the broadcast is pre-recorded

D. they don’t make the bulletins by themselves

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 17 to 24.

The difference between the nuclear family and the extended family is that a nuclear family refers to a single basic family unit of parents and their children, whereas the extended family refers to their relatives such as grandparents, in-laws, aunts and uncles, etc. In many cultures, and particularly indigenous societies, the latter is the most common basic form of social organization.

 A nuclear family is limited, according to Kristy Jackson of Colorado State University, to one or two parents (e.g. a father and mother) and their own child, or children, living together in a single house or other dwellings. In anthropology, they only must be related in this fashion; there is no upper or lower limit on the number of children in a nuclear family.

 The extended family is a much more nebulous term, but in essence refers to kin or relations not covered by the above definition. In historical Europe and Asia as well as in Middle Eastern, African, and South American Aboriginal cultures, extended family groups were typically the most basic unit of social organization. The term can differ in specific cultural settings, but generally includes people related in age or by lineage. Anthropologically, the term “extended family” refers to such a group living together in a household, often with three generations living together (grandparents, parents, and children) and headed in patriarchal societies by the eldest man or by some other chosen leadership figure. However, in common parlance, the term “extended family” is often used by people simply to refer to their cousins, aunts, uncles, and so on, even though they are not living together in a single group.

Historically, most people in the world have lived in extended family groupings rather than in nuclear families. This was even true in Europe and in the early United States, where multiple generations often lived together for economic reasons. During the 20^th century, average income rose high enough that living apart as nuclear families became a viable option for the vast majority of the American population. In contrast, many indigenous societies and residents of developing countries continue to have multiple generations living in the same household. The rise of the nuclear family in the modern West does not necessarily mean that family arrangements have stabilized, either. The rapid growth in single-parent households, for instance, also represents a substantial change in the traditional nuclear family. More couples are also choosing not to have children at all.

What can be inferred from the reading passage?

A. Indigenous communities have been completely eradicated all over the world.

B. In the future, all extended families will be replaced by nuclear ones.

C. Anthropology is a science concerning human race and its development.

D. Couples with no children can’t be defined as families.
