It's hard to give an exact number. It depends on the style and content of the novel. Some pages might have quite a few, while others might have fewer.
Well, that's a tricky one. It could vary a lot. If the writing is descriptive and complex, there might be more. But if it's straightforward, there could be fewer. So, there's no set amount.
Honestly, there's no fixed count. It depends on factors like the genre, the author's writing style, and the plot. Maybe one page could have a couple, or maybe none at all on some.
