Passage A:

Readers who study a difficult text on paper tend to remember its structure better than those who read the same text on a screen. The fixed geography of a printed page — this idea near the top of the left page, that one three pages on — gives memory something to hold. Scrolling erases those landmarks; every screen looks like the last. For sustained, careful reading, the physical book is not nostalgia but a tool matched to how memory works. Passage B:

The screen's advantage is not depth but reach. A student in a village with no library can open ten thousand books on a borrowed phone, search every one for a single phrase in seconds, and enlarge the type until failing eyes can read it. These are not small conveniences; for many readers they are the difference between reading and not reading at all. Whatever paper offers the practiced student, the screen offers the excluded one a way in.
