The rate of population growth is fastest in underdeveloped countries. In these countries a high birthrate is accompanied by a lowered death rate thanks to improved standards of public health. Ideally it should be possible to counter balance the effect of a reduced death rate by all increased use of family planning. In practice, however, population control is a complex matter. Throughout history people have determined the size of their families according to the cultural values of their societies.

Population control has long been a subject of discussion among researchers. Some have argued that the supply of good land is limited. In order to feed a large population, bad land must be cultivated and the good land overworked. As a result, each person produces less in a given amount of time and this means a lower average income than could be obtained with a smaller population. Other researchers have argued that a large population gives more scope for the development of facilities such as sports, roads and railways, which are not likely to be built unless there is a big demand to justify them. Similarly, it can be argued that the public costs of society will not be so heavy to each individual if they are shared among the members of a large population.

One of the difficulties in implementing birth control lies in the fact that the official attitudes to population growth vary from country to country. In underdeveloped countries where a large population is pressing hard upon the limits of food, space and natural resources, it will be the first concern of government to place a limit on the birthrate. In a well-developed society the problem may be more complex. A declining birthrate may lead to unemployment because it results in a shrinking market. Cities with a declining population may have to face the prospect of a shrinking tax base and a fall in land values. If there are fewer children going to school, teachers may be thrown out of work. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.

The writer suggests that policy makers should consider cultural values ______.

A．in carrying out family planning

B．in producing birth control drugs

C．in improving public health standards

D．in introducing birth control techniques

One reason for quick population increase in underdeveloped countries is that______.

C．improved public health standards have reduced death rate greatly

D．those countries have enough resources to support a large population

A change in the quality of fuel atomization by a diesel engine fuel injector would be caused by a/an ______.

B.increase in cylinder turbulence

C.leaking needle valve

D.reduction in cylinder turbulence

An increase in the fuel injection pump discharge pressure can be caused by a/an _______.

A.leaking delivery valve

Investment in the public sector, such as electricity, irrigation, public services and transport (excluding vehicles, ships and planes) increased by about 10%, although the emphasis moved to the transport and away from the other sectors mentioned. Trade and services recorded a 16%～17% investment growth, including a 30% increase in investment in business premises. Industrial investment is estimated to have risen by 8%. Although the share of agriculture in total gross in vestment in the economy continued to decline, investment grew 9% in absolute terms, largely spurred on by a 23% expansion of investment in agricultural equipment. Housing construction had 12% more invested in it in 1964, not so much owing to increased demand, as to fears of new taxes and limitation of building.

Total consumption in real terms rose by close on 11% during 1964, and per capital personal consumption by under 7%, as in 1963. The undesirable trend towards a rapid rise in consumption, evident in previous years, remained unaltered. Since at current prices consumption rose by 16% and disposable income by 13%, there was evidently a fall in the rate of saving in the private sector of the economy. Once again consumption patterns indicated a swift advance in the standard of living. Expenditure on food declined in significance, although consumption of fruit increased.

Spending on furniture and household equipment, health, education and recreation continued to increase. The greatest proof of altered living standards was the rapid expansion of expenditure on transport(including private cars) and personal services of all kinds, which occurred during 1964. The progressive wealth of large sectors of the public was demonstrated by the changing composition of durable goods purchased. Saturation point was rapidly being approached for items such as the first household radio, gas cookers, and electric, refrigerators, whereas increasing purchases of automobiles and television sets were registered.

the author thinks that the trend towards a rapid rise in consumption was "undesirable" because ______.

A．people saved less

B．people were wealthy

C．people consumed less

D．expenditures on luxuries increased
