问题     The advantages and disadvantages of a large population have long been a(n)【C1】______of discussion among economists. It has been argued that the supply of good land is limited. To 【C2】______ a large population, the good land must be worded intensively and the【C3】______ land must be cultivated. Thus, each person 【C4】______less and this means a lower average income【C5】______ could be obtained with a smaller population. Other economists have argued that a large population gives more【C6】______for specialization and the development of facilities. 【C7】______there is a big demand to justify them, facilities such as ports, roads and railways are not【C8】______to be built.
    One of the difficulties in【C9】______a worldwide birth control program lies in the fact that official attitudes to population growth【C10】______from country to country depending on the level of industrial development and the availability of food and【C11】______ materials. In the developing country where a vastly【C12】______population is pressing harder and harder【C13】______the limits of food, space and natural resources, it will be the first concern of government to place a limit on the birth rate,【C14】______the consequences may be.
    In the highly industrialized society the problem may be more【C15】______. A decreasing birth rate may lead to unemployment because it results 【C16】______a declining market for manufactured goods.【C17】______ the pressure of population on housing declines, prices also decline and the building【C18】______ is weakened.

【C16】
选项 A、in
B、from
C、to
D、for
答案A
解析 介词辨析题。result后面引出的是结果，因此选[A]in，result in的意思是“导致，结果是”。result from的意思与result in相反，是“起因于”，因此可以排除[B]；[C]to和[D]for很少和动词result连用，故均排除。
