THE NIGHTMARE OF POPULATION GROWTH
One of the most (1)..................problems facing us now is the need to control population growth so that people in the twenty-first century stand a chance of survival. Although the birth rate in developed countries has fallen, it (2) .................. to rise in poorer countries as a result of better medical care. It is1 hard to understand the phenomenal growth in population that has (3)..................place this century. Around the first century A.D. there (4).................. probably between 250 and 350 million people in the world. Sixteen centuries later, the number had risen to only 500 million. (5).................., for more than three quarters of time between Christ and the present day, world population (6) .................. rose.
Then, slowly, the rise began. By 1900 it was 1,500 million. Now it is 4,700 million. The increase in the past 65 years - less than the average life-time of an English person today - has equaled the entire increase in the previous 100,000 years of human existence. (7).................., the rate of increase, now close to twenty per cent a decade, is still shooting up. According to United Nations estimates, the population of the world will have risen to (8) .................. 6,000 million by the end of the century. While the rate of increase is only seven per cent a decade in Western Europe, in many developing countries it is (9)..................twenty-five and thirty per cent. Obviously, population control will be one of the biggest problems facing the twenty-first century. Despite all the (10) ..................signs, too little is being done too late.

VI. Read the passage below and choose the best answer (A, B, C or D) to each question.
The population of the world has increased more in modern times than in all other ages of history combined. World population totaled about 500 million in 1650. It doubled in the period from 1650-1850. Today the population is more than five billion. Estimates based on research by the United Nations indicate that it will more than double in the twenty-five years between 1915 and the year 2000, reaching seven billion by the turn of the century.
No one knows the limits of population that the earth can support. Thomas Malthus, an English economist, developed a theory that became widely accepted in the nineteenth century. He suggested that because world population tended to increase more rapidly than the food supply, a continual strain was exerted upon available resources. Malthus cited wars, famines, epidemics, and other disasters as the usual limitations of population growth.
With recent advances in science and technology, including improved agriculture methods and great strides in medicine, some of the limiting factors in population growth have been lessened, with obvious results. International organizations have put forward several recommendations to alleviate the problem of overpopulation, including an increase in food production, genera! economic development in target areas, and a decrease in birth rates. Most experts agree that it will be necessary to combine all three recommendations in an effort to effect a lasting solution.
