This section tends to highlight information that may be discussed in other sections of this guide, but presented in a different format. But sometimes this section presents new information not discussed elsewhere in the book.
One of the things the Q&A format allows for is presenting information from a different perspective. This perspective change can sometimes allow the reader to more quickly and firmly grasp the presented information. Also, this format may combine information that spans across multiple chapters of the guide, but brings it together in one discussion. This simple format can expose the reader to connections and observations that are not as obvious to tie together when presented in anther format.
