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.
In the second paragraph, the word"maintained"most closely means______.

选项 A、taken care of
B、supported
C、used
D、announced

答案B

解析 由第二段第一句可知,过去出版业常常支持图书馆拥有自由分发出版物的权力。
