单项选择题

Last week, Education Secretary Arne Duncan declared a war on paper textbooks. "Over the next few years," he said, "textbooks should be out of use." In their place would come a variety of digital-learning technologies, like e-readers and multimedia Websites.
Such technologies certainly have their place. But Duncan is threatening to light a fire to a tried-and-true technology—good old paper—that has been the foundation for one of the great educational systems on the planet. And while e-readers and multimedia may seem appealing, the idea of replacing this learning platform with a widely promoted but still unproven one is extremely dangerous.
A renowned expert on reading, Maryanne Wolf, has recently begun studying the effects of digital reading on learning, and so far the results are mixed. She worries that Internet reading, in particular, could be such a source of distractions for the student that they may cancel out most other potential benefits of a Web-linked, e-learning environment. And while the high-tech industry has sponsored substantial amounts of research on the potential benefits of Web-based learning, not enough time has passed for successive studies to demonstrate the full effects.
In addition, digital-reading advocates claim that lightweight e-books benefit students’ backs and save schools money. But the rolling backpack seems to have solved the weight problem, and the astounding costs to equip every student with an e-reader, provide technical support and pay for regular software updates promise to make the e-textbook a very expensive option.
My point is that we shouldn’t jump at a new technology simply because it has advantages; only time and study will reveal its disadvantages and show the value of what we’ve left behind, which brings us back to paper. With strength and durability that could last thousands of years, paper can preserve information without the troubles we find when our most cherished knowledge is stuck on an unreadable floppy disk or lost deep in the "cloud." Paper textbooks can be stored and easily referenced on a shelf. They are easy to read and don’t require a battery or plug. Though the iPad and e-readers have increasingly better screen clarity, the idea that every time a person reads a book, newspaper or magazine in the near future they will require an energy source is frightening.
The digitization of information offers important benefits, but before we tear into pieces the last of the paper textbooks, let us pause and think more about it. What is the most suitable title for the passage

A. No More Textbooks
B. Here Comes E-reading
C. Textbooks or E-textbooks
D. The Truth About E-reading
