问题     Libraries have traditionally been the public’s access to the important sources of information that are necessary to function in today’s highly technical world. That function has been called into question by the fast-paced development of digital media over the past several decades. In order to continue to fulfill public interests, libraries everywhere are forced to develop means of granting access to these expensive new services to average citizens.
    In the past, the publishing industry maintained the rights of libraries to freely distribute published materials because the libraries bought so many of their books. Because the new electronic publications can easily be copied in their entirely by patrons of the library system. There have even been attempts to stop libraries from distributing digital media.
    In addition to waning(衰落的)cooperation of the publishing industry, there is the problem that the newer forms of information are much more specialized than those which they replace. Deciding how to divert already limited resources is increasingly difficult as the options multiply. Whereas a single reference index may have covered an entire field in the past, now there are frequently several specialized indexes available in electronic form. In order to continue to make use of the newer technology, the libraries must decide which materials are most useful to the majority of the patrons. There are many different solutions being applied, but only the process of trial and error will determine the most effective strategy.
How will the most effective decision be determined?
选项 A、A special commission will study the task.
B、The government will examine the situation.
C、It will be decided by experimentation.
D、The voters will decide.
答案C
解析 由文中最后一句话可知，最有效的战略只有经过反复实验才能得出。
