Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
In a library, there are five bookshelves labeled A, B, C, D, and E. Each shelf contains books from different genres: mystery, romance, science fiction, history, and biographies. The librarian decides to reorganize the shelves by swapping the mystery and romance sections and moving the science fiction section to a different part of the library. She leaves the history and biography sections untouched. Two regular patrons, John and Mary, visit the library after the changes have been made. What do they think has happened to their favorite sections, and how might this affect their book selections? Provide a brief response.

### Response:

John and Mary's experience in the library depends on what their favorite sections are. If John's favorite section is mystery and Mary's is romance, they might initially think their favorite sections have been removed when they don't find them in their usual places. However, upon further exploration, they would discover that the bookshelves have been reorganized and their preferred genres have been swapped. This means that John would find the romance books where he expected to find mystery, and Mary would find the mystery books where the romance used to be.

If John's or Mary's favorite section is science fiction, they would notice that this section has been completely moved to a different part of the library. They would need to ask the librarian where the science fiction books have been relocated to find their favorite genre.

For patrons whose favorite sections are history or biographies, nothing would seem amiss because these sections have remained in their original locations, untouched by the reorganization.

The reorganization of the bookshelves might affect John's and Mary's book selections if they have a hard time finding their favorite genres. If they do not ask the librarian for help or if they do not explore the library sufficiently, they might choose books from the genres that have replaced their favorites--or they might leave without checking out any books at all. However, if they are open to exploring different genres or if they easily adapt to the changes, they might discover new books that they wouldn't have picked up before, thus potentially broadening their reading preferences.
