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. 

     Scientists have identified two ways in which species disappear. The first is through ordinary or "background" extinctions, where species that fail to adapt are slowly replaced by more adaptable life forms.  The second is when large numbers of species go to the wall in relatively short periods of biological time. There have been five such extinctions, each provoked by cataclysmic evolutionary events caused by some geological eruption, climate shift, or space junk slamming into the Earth. Scientists now believe that another mass extinction of species is currently under way - and this time human fingerprints are on the trigger. 

     How are we are doing it? Simply by demanding more and more space for ourselves. In our assault on the ecosystems around us we have used a number of tools, from spear and gun to bulldozer and chainsaw.  Certain especially rich ecosystems have proved the most vulnerable. In Hawaii more than half of the native birds are now gone some 50 species. Such carnage has taken place all across the island communities of the Pacific and Indian oceans. While many species were hunted to extinction, others simply succumbed to the “introduced predators” that humans brought with them: the cat, the dog, the pig, and the rat.

     Today the tempo of extinction is picking up speed. Hunting is no longer the major culprit, although rare birds and animals continue to be butchered for their skin, feathers, tusks, and internal organs, or taken as savage pets. Today the main threat comes from the destruction of the habitat of wild plants, animals, and insects need to survive. The draining and damming of wetland and river courses threatens the aquatic food chain and our own seafood industry. Overfishing and the destruction of fragile coral reefs destroy ocean biodiversity. Deforestation is taking a staggering toll, particularly in the tropics where the most global biodiversity is at risk. The shrinking rainforest cover of the Congo and Amazon River basins and such place as Borneo and Madagascar have a wealth of species per hectare existing nowhere else. As those precious hectares are drowned or turned into arid pasture and cropland, such species disappear forever

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 39 to 43.

     One way of training for your future occupation in Germany is by pursuing a dual vocational training programme. Such programmes offer plenty of opportunities for on-the-job training and work experience.  Programmes usually last between two and three and a half years and comprise theoretical as well as practical elements. You will spend one or two days a week, or several weeks at once, at a vocational school where you will acquire the theoretical knowledge that you will need in your future occupation. The rest of the time will be spent at a company. There you get to apply your newly acquired knowledge in practice, for example by learning to operate machinery. You will get to know what your company does, learn how it operates and find out if you can see yourself working there after completing your training. 

     This combination of theory and practice gives you a real head start into your job: by the time you have completed your training, you will not only have the required technical knowledge, but you will also have hands-on experience in your job. There are around 350 officially recognised training programmes in Germany, so chances are good that one of them will suit your interests and talents. You can find out which one that might be by visiting one of the jobs vocational training fairs which are organised in many German cities at different times in the year. 

     Employment prospects for students who have completed a dual vocational training programme are very good. This is one of the reasons why this kind of training is very popular with young Germans: around two thirds of all students leaving school go on to start a vocational training programme.

Which of the following statements best describes the dual vocational training programmes
