阅读理解-We learn from the last sentence of the passage that _____.
For many years, people have tended to think of natural resources as stacks of raw material piled up in a storehouse.A person with this sort of picture in his mind logically assumes that the more you use of any natural resources, the sooner you get to the bottom of the pile.Now we are beginning to discover that the idea of a storehouse does not correspond with reality.Instead, the fact seems to be that the first storehouse in which man found himself was only one in a series.As he used up what was piled in that first room, he found he could open a door into a much larger room.And as he used the contents of this larger room, he discovered there was another room beyond larger still.This concept of limitless raw material is not new.It is held by a number of persons.But it is an idea certainly not familiar to people at large. It does not mean that progress is simple and that Utopia is near at hand.On the contrary, raw materials, no matter how vast in amount, do not become available resources until human thought and effort are applied to them.In a very real sense raw material; do 17ot exist, they are created, We know, for example, that in a region of great mineral wealth, people can live out their lives in extreme poverty if they do not realize the wealth exists or if they do not know how to get at it.It is use that makes it valuable.Even when the wealth is made available through technical means, the accelerating growth of populations and the enormous wastage of war are additional complications to consider.
阅读理解
A.the availability of raw materials also depends on war
B.continued expansion of scientific knowledge will prolong the usage of raw materials
C.political and social will also decide the availability of raw materials
D.war and population are severe problems
我个人认为这个应该是：C
解析：文章最后一句说“即使通过技术手段使这些财富变为可用时，不断加速增长的人口和战争带来的巨大浪费也是需要加以考虑的复杂因素”。可见社会问题（人口）和政治问题（战争）也会影响自然资源的可利用性，故答案为C。注意，选项D的陈述也是正确的，但全文都是关于自然资源的，所以D是离题的。
