Answer:
The book may be introductory, but it can satisfy a scholar.
Explanation:
In any argument presentation be it in an academic paper or any book for that matter, the presence of any phrases like "sound lines' ' will show an emphasis on the fact that the presented argument is to a certain extent, true and has validation. At the same time, the words "amply provide" will imply that the sources or argument presented is enough to prove the given point. These two phrases thus, help make the argument that the given points may be introductory but at the same time, they can also satisfy a scholar's viewpoint.
Books, and other things etc.
