Answer to Question 1
It is easy to confuse structural with static. After all, this book discusses behavioral and dynamic modeling, so static modeling should not be a far-fetched conclusion. But whether static modeling is meaningful or not, structural modeling is not static: it models not only the building blocks of an entity, but also the relationships among them. And in a system, closed or open, software or otherwise, relationships are never static.
