When the first Harry Potter book appeared, in 1997, it was just a year before the universal search engine Google was launched. And so Hermione Granger, that charming grind, still goes to the Hogwarts library and spends hours and hours working her way through the stacks, finding out what a basilisk is or how to make a love potion, while the kids who have since come of age nudge their parents. ‘Why is she doing that?’ they whisper. ‘Why doesn’t she just Google it?’That the reality of machines can outpace the imagination of magic, and in so short a time, does tend to lend weight to the claim that the technological shifts in communication we’re living with are unprecedented. It isn’t just that we’ve lived through one technological revolution among many; it’s that our technological revolution is the big social revolution that we live with. The past twenty years have seen a revolution less in morals, which have remained mostly static; the change has been our ability to tweet or IM or text it. The subject our novelists focus on is information; the obsession of our intelligentsia is what it does to our intelligence.The scale of the transformation is such that an ever-expanding literature has emerged to censure or celebrate it. A series of books explaining why books no longer matter is a paradox that Sherlock Holmes would have found implausible, yet there they are, and they come in the typical flavours: the eulogistic, the alarmed, the sober and the gleeful. When the electric toaster was invented, there were, no doubt, books that said that the toaster would open up horizons for breakfast undreamed of in the days of burning bread over an open flame; books that told you that the toaster would bring an end to the days of creative breakfast, since our children, growing up with uniformly sliced bread, made to fit a single opening, would never know what a loaf of their own was like; and books that told you that sometimes the toaster would make breakfast better and sometimes it would make breakfast worse, and that the cost for finding this out would be the price of the book you’d just bought.Which of the following best describes the style of the passage?ArgumentativeNarrativeAnalyticalDescriptive
