Greenhouse gases arise from a wide range of sources and their increasing concentration is largely related to the compound effects of increased population, improved living standards and changes in lifestyle. From a current base of 5 billion, the United Nations predicts that the global population may stabilize in the twenty- first century between 8 and 14 billion, with more than 90 percent of the (1) ______ increase place in the world's developing nations. The (2) ______ activities to support that growth, particularly to produce the required energy and food; will cause further increases in greenhouse gas emissions. The challenge, therefore, is to attain a (3) ______ balance between population, economic growth and the environment.

B. projected
C. wanted
D. calculated
A remarkable

Clean coal is another avenue for improving fuel conversion efficiency. Investigations are under (8) into super- clean coal (35 percent ash) and ultraclean coal (less than 1 per cent ash). Super- clean coal has the potential to enhance the combustion efficiency of conventional stabilized fuel power plants. Ultraclean coal will enable coal to be used and in (9) power systems such as coal- fired gas turbines which, when (10) in combined cycle, have the potential to achieve much greater efficiencies.

It has demonstrated that men were already traveling across the snow by means of primitive skis before the invention of the wheel. In the Asiatic region of Altai and in Scandinavia, for example, the remains of skis have been found which dated back to 4,000 BC. Further evidence is supplied by ancient cave paintings which depict people skiing, and a Norway saga which tells the story of an invasion of its territory 8,000 years ago by a tribe of skiers who came from the north.
Nowadays, skiing, apart from a sport, has become a big industry and a notable feature of leisure culture. Ski resorts and all the activity that they generate is the main source of wealth in many mountain regions, which were previously remote and accessible. And far from its once elitist image, skiing is now enjoyed by an increasingly broader spectra of society.
