SECTION A

Directions: Read the passage and answer questions 1-8.
It is impossible to approach the question of overpopulation apolitically, because, not surprisingly, demographic patterns are dissimilar around the world, and questions of religion, culture, government, and degree of industrial development affect these patterns. In industrialized nations, birthrates are, for the most part, lower than death rates. But in Asia and Africa, many countries have annual growth rates of2.5 to 3.5 per cent. The ability ofmost ofthese rapidly increasing populations to find food, water, shelter, and warmth is diminished as the population increases; people are forced to try to grow food and raise livestock on tnarginalland, which only exacerbates problems of erosion and deforestation. Concerns about air and water pollution are ignored in the scramble for food and fuel, with the result that as the population grows, the land is less able to sustain those already living on it. Pressure on already depleted natural resources could result in fundamental changes to local or even global ecosystems, changes that may be permanent. In order to keep environmental damage from escalating to the point at which it is irreversible, industrialized nations should at least offer support to undeveloped countries in the form ofeducation about sanitation and family planning, and ideally should begin work on the long-range goal ofworldwide population stability.

A. point out that a potentially disastrous mistake was made when world leaders failed to take political responsibility for the problems of overpopulation

D. industrialized nations should share some oftheir agricultural abundance with developing nations
3. The author mentions which ofthe following as a factor influencing a country's demographic patterns?
