I think the answer is C. Good luck!
From all these excerpts of "Lifeboat Ethics: The Case Against Helping the Poor", the last sentence is the one that provides an example of logos because it gives clear and compelling information that helps address the topic by employing reason.
It provides hard data through statistics, to argue his case and convince the reader to believe his ideas.
If the options are:
<span>A. what you already know about the topic
B. your favorite book or story of all time
C. how long you planned to read that day
D. who else has mentioned the book to you
Then the correct answer is A. what you already know about the topic. This is the only relevant thing for the reading, and not your favorite book, or plans for the reading, or recommendations. Many books often require some kind of foreknowledge about the subject. For example, if you want to read a novel about WW2, you will need to know at least the basics of this historical event. Even if you don't know too much about it, try to remember some basic facts.
