Read the passage.
When the town library in Sankar began lending laptops as well as books, the librarian expected students to borrow them for games. Instead, the most borrowed laptop went to a retired tailor who wanted to read the newspaper in larger print. Within a year the library's visitors had doubled, and most of the new visitors were over sixty. The librarian now runs a weekly class, taught by school students, on sending photographs to grandchildren.
