Hi,

"
Some university textbooks are rigorous but impenetrable, and the authors should strike a balance between imparting knowledge and whetting students’ appetite for learning facts and details.
"
Here, what are the differences if I use "obscure" to replace the "impenetrable"?
I am very interested in any slight difference, if any, to native speakers.

Thank you!

    Hullo MB. Basically, obscure means 'difficult to understand'; impenetrable means 'impossible to understand'.
