How would you use the concepts from Ch. 8 in a real-life situation? Describe how these concepts might be useful.

You seem to be ignorant of the function of the Jiskha forum. Let me educate you.

1. Jiskha is staffed by volunteers who help students from around the world with their academic studies.
2. Jiskha does not have an affiliation with any school, nor does it have access to any of a school's text books.
3. Jiskha requests that each person type the school subject on the appropriate line.

To answer your question, I will need to know which specific book or topic you are referring to in Chapter 8. Could you please provide more information or context?
