Part 2: Fill in each gap with a suitable word (2 pts) There is no other race (1) quite like it, no other race in a play so inaccessible, no other race. which puts the body through an unendurable test (2) of such extremes. The Antarctic Ice Marathon was the brainchild of Richard Donovan, (3)whose company, Polar running Adventures, give runner the opportunity to partake in a race through the barren wasteland that is the snow-covered Union glacier. Last year, there were some 34 participants in the race, and, this time, the number of entrants is expected to be higher still; such has been the level of interest shown by members of the public, (4)amateur and professional athletes and the media (5) alike 

But, while the prospect of being part of as unique an experience as the Antarctic Ice Marathon is, seems, on the (6)face it, a rather agreeable notion, (7) those considering putting their names in the mix would do well to be mindful of just how intense and demanding (8)both physically and psychologically, the event can be. You will be cut off completely from civilization, and you may be accustomed to dealing with, not to (9)mention the improbability of fine weather-think instead near whiteout conditions and zero visibility. But if you still fancy (10)giving it a go, get in touch with Richard and he can make your dream come true. 

Part 3. Read the following passage and choose the correct answer to each of the questions (2 ps) 

Population ecology is the science that measures changes in population size and composition and identifies the causes of these fluctuations. Population ecology is not concerned solely with the human population. In ecological terms, a population consists of the individuals of one species that Simultaneously occupy the same general area, rely on the same resources, and are affected by similar environmental factors. The characteristics of a population are shaped by its size and by the interactions among individuals and between individuals and their environment. 

Population size is a balance between factors that increase numbers and factors that increase numbers and factors that decrease numbers. Some factors that increase populations are favourable light and temperature, adequate food supply, suitable habitat, ability to compete for resource, and ability to adapt to environmental change. Factors that decrease populations are insufficient or excessive light and temperature, inadequate food supply, unsuitable or destroyed habitat, too many competitors for resources, and inability to adapt to environmental change. 

Another important characteristic of any population is its density. Population density is the number of individuals per units, such as the number of maple trees per square kilometer in a county. Ecologists can rarely determine population size by actually counting all Individuals within geographical boundaries. Instead, they often use a variety of sampling techniques to estimate densities and total population sizes. For example, they might estimate the number 

of black bears in a national park by counting individuals in a few sample plots representative of the whole park. In some cases, they estimate population size through indirect indicators, such as the number of nests or burrows, or signs such as tracks or droppings. 

Another important population characteristic, dispersion, is the pattern of spacious among Individuals within the population's geographical boundaries. Various species are distributed In their habitats in different ways to take better advantage of food supplies and shelter, and to avoid predators or find prey. Within a population's range, densities may vary greatly because not all areas provide equally suitable habitat, and also because individuals space themselves in relation to other members of the population.
