Read the following text and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questionsMany ants forage across the countryside in large numbers and undertake mass migrations; these activities proceed because one ant lays a trail on the ground for the others to follow. As a worker ant returns home after finding a source of food, it marks the route by intermittently touching its stinger to the ground and depositing a tiny amount of trail pheromone – a mixture of chemicals that delivers diverse messages as the context changes. These trails incorporate no directional information and may be followed by other ants in either direction.Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones. Ants can be extremely sensitive to these signals. Investigators working with the trail pheromone of the leafcutter ant Atta texana calculated that one milligram of this substance would suffice to lead a column of ants three times around Earth.The vapor of the evaporating pheromone over the trail guides an ant along the way, and the ant detects this signal with receptors in its antennae. A trail pheromone will evaporate to furnish the highest concentration of vapor right over the trail, in what is called a vapor space. In following the trail, the ant moves to the right and left, oscillating from side to side across the line of the trail itself, bringing first one and then the other antenna into the vapor space. As the ant moves to the right, its left antenna arrives in the vapor space.The signal it receives causes it to swing to the left, and the ant then pursues this new course until its right antenna reaches the vapor space. It then swings back to the right, and so weaves back and forth down the trail.According to the passage, why do ants use different compounds a trail pheromones?

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.What does the word “this” in paragraph 5 refer to?

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 20th 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.The word “viable” in paragraph 4 could be best replaced by _______.
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.

Instructors at American colleges and universities use many different teaching methods. Some instructors give assignments everyday. They grade homework. Students in their classes have to take many quizzes, a midterm exam, and a final test. Other instructors give only writing assignments. Some teachers always follow a course outline and usually use the text book. Others send students to the library for assignments. The atmosphere in some classrooms is very formal. Students call their instructors “Professor Smith,” “Mrs Jones,” and so on. Some teachers wear business clothes and give lectures. Other classrooms have an informal atmosphere. Students and teachers discuss their ideas. Instructors dress informally, and students call them by their first names. American teachers are not alike in their teaching styles. At most American colleges and universities, facilities for learning and recreation are available to students. Students can often use type-writers, tape recorders, video machines, and computers at libraries and learning centres. They can buy books, notebooks, and other things at campus stores. They can get advice on their problems from counselors and individual help with their classes from tutors. Students can relax and have fun on campus, too. Some schools have swimming pools and tennis courts. Most have snack bars and cafeterias.Where do students and teachers discuss their ideas?

Advertising helps people recognize a particular brand, persuades them to try it, and tries to keep them loyal to it. Brand loyalty is perhaps the most important goal of consumer advertising. Whether they produce cars, canned foods or cosmetics, manufacturers want their customers to make repeated purchases. The quality of the product will encourage this, of course, but so, too, will affect advertising. Advertising relies on the techniques of market research to identify potential users of a product. Are they homemakers or professional people? Are they young or old? Are they city dwellers or country dwellers? Such questions have a bearing on where and when ads should be placed. By studying readership breakdowns for newspapers and magazines as well as television ratings and other statistics, an advertising agency can decide on the best way of reaching potential buyers. Detailed research and marketing expertise are essential today when advertising budgets can run into thousands of millions of dollars. Advertising is a fast-paced, high-pressure industry. There is a constant need for creative ideas that will establish a personality for a product in the public's mind. Current developments in advertising increase the need for talented workers. In the past, the majority of advertising was aimed at the traditional white family - breadwinner father, non- working mother, and two children. Research now reveals that only about 6 percent of American households fit this stereotype. Instead, society is fragmented into many groups, with working mothers, single people and older people on the rise. To be most successful, advertising must identify a particular segment and aim its message toward that group. Advertising is also making use of new technologies. Computer graphics are used to grab the attention of consumers and to help them see products in a new light. The use of computer graphics in a commercial for canned goods, for instance, gave a new image to the tin can.The author implies that the advertising industry requires______.
