The survival of the publishing industry depends upon the existence of a public who will buy the printed word in the form of newspapers, books and magazines. Overthe past several years, however,the advance of electronic media, particularly CDROMs, online computer services, and the Internet, has made information
available to the public electronically without the need for printed materials. As the availability of electronic media increases and as it is more easily accessible, the
public has less need for printed materials. So the publishing industry is threatened by the advance of the computer information age.



这是9道BF里面的第8题，标准的思路是：
The survival of the publishing industry depends upon the existence of a public who will buy the printed word in the form of newspapers, books and magazines.（premise） Over the past several years, however, the advance of electronic media, particularly CDROMs, online computer services, and the
Internet, has made information available to the public electronically without the need for printed materials.(已经的的确确发生了的fact) As the availability of electronic media increases and as it is more easily accessible, the public has less need for printed materials.（作者的证据） So the publishing industry is threatened by the advance of the computer information age. （作者的推论）

可是为什么第一句话不是principle呢？那principle和premise的区别又是什么？
快被BF弄疯了，请大家帮我分析分析那，小女子在此先道谢了...

原题来咯，请帮我看看吧，还是那个问题---其他的我都有分析对，但就是第一句话是在晕的不成，为嘛就不是principle呢
The survival of the publishing industry depends upon the existence of a public who will buy the printed word in the form of newspapers, books and magazines. Over the past several years, however, the advance of electronic media, particularly CD-ROMs, online computer services, and the Internet, has made information available to the public electronically without the need for printed materials. As the availability of electronic media increases and as it is more easily accessible, the public has less need for printed materials. So the publishing industry is threatened by the advance of the computer information age.
The two portions in boldface play which of the following roles?
(A) The first is the part of evidence that the argument includes, the second is the conclusion that can be drawn only from the first.
(B) The first is the second-premise that the argument includes; the second is the conclusion that is reasonably drawn form this passage.
(C) The first is the second-premise that the argument includes, the second is the inference that must be drawn from this argument.
(D) The first is the fact that must be true, the second is the inference that can be correctly drawn from this argument.
(E) The first is the part of premise that the argument depends on; the second is the conclusion that is incorrectly drawn from this argument

我选了B，但是按照你的解释应该是选择D吧。
我觉得主要还是第一部分的问题，到底是premise，还是fact.
Overthe past several years, however,the advance of electronic media, particularly CDROMs, online computer services, and the Internet, has made information
available to the public electronically without the need for printed materials.
我觉得这句话应该讲述的是一个已经发生的事实。第一句话中的depends on 说明应该是premise.
