(B)教えて欲しいです😭😭 答えは preserve culture になります。 解説では(7)の2文目と(3)の最後から3文目を参照とかいてありますがそれでも意味がわからないです。

3 次の文章を読んで, あとの各問に答えよ。 (*印の付いている単語·語句には, 本文のあとに [注] がある。) When we go to the library, we read books/*search for and/share information and have a *discussion with others. // Libraries are very convenient places. /The library has a long history of collecting and keeping books. /Books have been an important part of culture. Around 1445 Johann Gutenberg *invented the *printing machine./ Libraries began to collect the hooks *printed by the printing machine, and the number of libraries grew./ Now some libraries have begun to *digitalize a lot of books. Some people say most of the books will become digitalized *data/ When 声った all the books are digitalized, what will the future of the library be? / Some even say the library will disappear. Will that really happen? To answer this question, we first have to see how people have digitalized books. We can say the idea of digitalizing books began with Michael Hart in 1971/ He was able to use an expensive computer,/so he thought he could do something good for other people by using it. A computer can keep a lót of data/and it can search for the data in a very short time./When the computer has a lot of digitalized data from the books, these data become an important part of culture. / Michael Hart thought that people would use these data as they like, His idea became a *project. /He couldn't digitalize books which had *copyright, so he digitalized books which were *in the public domain and collected them in a computer./ People were able to read the distalized books without *paying any money. Hart named his project “Project Gutenberg," |He thought his project was as important as Gutenberg's printing machine, because the printing machine also spread knowledge 知識てめる all over the world. / Project Gutenberg continues even after Hart died in 2011. Now you can read - 4
