There is no one answer because its hard to decide what counts as a word
Reading nonfiction can yes, be a bit boring. When you annotate the text you start understanding the text more, more so because it's about real life events. Giving examples and writing notes to understand does help you know what you're reading. By looking back on what you've written about the text it can help you understand what is going on.
Hope this somewhat helps!
The word that means “choice” is voice because your voice is what you say and stand for
