Final answer:
The exact page number for the quote from The Hobbit regarding Mr. Baggins killing the spider cannot be provided without knowing the edition of the book. Different editions will have the passage on different pages, typically found in 'Chapter 8 - Flies and Spiders'.
Step-by-step explanation:
The quote "somehow the killing of the giant spider, all alone by himself in the dark without the help of the wizard or the dwarves or of anyone else, made a great difference to Mr. Baggins. He felt a different person, and much fiercer and bolder in spite of an empty stomach" is from J.R.R. Tolkien's The Hobbit. To find the exact page number, you will need a physical copy of the book, as different editions will have this quote on different pages. For example, in the 75th-anniversary edition of The Hobbit, you might find this passage in 'Chapter 8 - Flies and Spiders'.
If you are looking for the page number for a class assignment or reference, it is best to use the specific edition of the book provided by your instructor or one that you have been citing in your work. If you do not have access to the physical book, you can often find extracts or certain passages of books through online databases or previews provided by book retailers.
