  1. Alter the code that introduces the back to top links, so that the links only appear after the fourth paragraph.
  2. When a back to top link is clicked on, add a new paragraph after the link containing the message You were here. Ensure that the link still works.
  3. When the author's name is clicked, turn it bold (by adding an element, rather than manipulating classes or CSS attributes).
  4. Challenge: On a subsequent click of the bolded author's name, remove the <b> element that was added (thereby toggling between bold and normal text).
  5. Challenge: Add a class of inhabitants to each of the chapter's paragraphs without calling .addClass(). Make sure to preserve any existing classes.
