Why might reading a book that you checked out from the library seem to be an example of a recreational activity that is totally uncommercialized but still be directly connected to commercial activity?

A) You had to eat and pay for utilities on the day you went to the library.
B) You might learn something valuable by reading.
C) Books from libraries are expensive, as they have expensive bindings.
D) People were paid to write, edit, print, ship, and shelve the book.

Even though checking out books from the library may seem uncommercialized, it is directly connected to commercial activity because people were paid to write, edit, print, ship, and shelve the book. While choices A and B may also be true, they are not directly related to the commercial activity involved in producing the book. Choice C is incorrect because libraries typically buy books with durable, inexpensive bindings to ensure that they last through multiple readings.
