The correct answer is D. To explain the many reasons why people prefer printed books
Step-by-step explanation:
The author's purpose in a text refers to the reasons or motives to write the text and the expectation the writer has about the text. In the passage presented it is likely the main purpose is to explain the reasons why people prefer printed books rather than e-readers (last option).
This is because the author mentions "many people still prefer to read printed books" in the first sentence and then the author adds multiple reasons to explain this preference, this includes that the physical features of books create an experience that is enjoyable"Some people even love the smell of books", that these are easier to read "easier to read because there’s no glare" and even that books are related to personality as the author mentions "share information about their owner’s interests. This shows the author is just explaining the reasons why people feel printed books are better without trying to persuade or convince the reader about which types of books are better.
