Read the following passage. Choose from the sentences A—G the one which best fits each gap of 61— 65. There are two extra sentences which you do not need to use.
All these activities may have damaging environmental impacts. For example, land clearing for agriculture is the largest single cause of deforestation: chemical fertilizers and pesticides may contaminate water supplies: more intensive farming and the abandonment of fallow periods tend to exacerbate soil erosion: and the spread of monoculture and use of high-yielding varieties of crops have been accompanied by the disappearance of old varieties of food plants which might have provided some insurance against pests or diseases in future.
【R1】______The United States, where the most careful measurements have been done, discovered in 1982 that about one-fifth of its farmland was losing topsoil at a rate likely to diminish the soil’s productivity. The country subsequently embarked upon a program to convert 11 percent of its cropped land to meadow or forest. Topsoil in India and China is vanishing much faster than in A-merica.
【R2】______In the rich countries, subsidies for growing crops and price supports for farm output drive up the price of land. The annual value of these subsidies is immense: about $250 billion, or more than all World Bank lending in the 1980s. To increase the output of crops per acre, a farmer’s easiest option is to use more of the most readily available inputs: fertilisers and pesticides. Fertiliser use doubled in Denmark in the period 1960—1985 and increased in the Netherlands by 150 percent. The quantity of pesticides applied has risen too: by 69 percent in 1975—1984 in Denmark, for example, with a rise of 115 percent in the frequency of application in the three years from 1981.
【R3】______The most dramatic example was that of New Zealand, which scrapped most farm support in 1984. A study of the environmental effects, conducted in 1993, found that the end of fertiliser subsidies had been followed by a fall in fertiliser use(a fall compounded by the decline in world commodity prices, which cut farm incomes). The removal of subsidies also stopped land-clearing and over-stocking, which in the past had been the principal causes of erosion. Farms began to diversify. The one kind of subsidy whose removal appeared to have been bad for the environment was the subsidy to manage soil erosion.
【R4】______Such countries also try and to introduce new payments to encourage farmers to treat their land in environmentally friendlier ways, or to leave it fallow. It may sound strange but such payments need to be higher than the existing incentives for farmers to grow food crops. Farmers , however, dislike being paid to do nothing. In several countries they have become interested in the possibility of using fuel produced from crop residues either as a replacement for petrol(as etha-nol)or as fuel for power stations(as biomass). Such fuels produce far less carbon dioxide than coal or oil, and absorb carbon dioxide as they grow.
【R5】______But they are rarely competitive with fossil fuels unless subsidized—and growing them does no less environmental harm than other crops.

G. Although all of them can produce poisonous gas through burning. [br] 【R5】
