문제 2For most of the twentieth century, a library was simply a quiet room full of books, and visitors were expected to stay ①silent while they searched the shelves. Today, many public libraries look completely ②similar. Alongside the usual shelves, you might find group study rooms, comfortable sofas for reading, computer labs, and even small recording studios for podcasts. Librarians say this change did not happen by ③accident. As more information moved online, fewer people needed a library simply to find facts, so librarians began asking what their communities actually needed instead. The answer, in many neighborhoods, turned out to be space itself: a warm, ④free place where students could study together, job seekers could print a resume, and children could attend a story hour. Some critics worry that libraries are drifting away from their original mission of preserving books, but librarians respond that a library survives only by ⑤changing with its readers.
