So you want me to make a sentence that has which, Who and where in it?
Answer:
GIve me more information if this question is lacking detail but I don't know what "the excerpt" is.
Explanation:

The definition of these two terms are as follows: "involving or causing a complete or dramatic change" and "breaking new ground; innovative; pioneering."
Their are lots of methods on being astute (:
