The authors of two new books demonstrate why and how.

At one point, the author demonstrates on a chalkboard her by-the-numbers technique.

At the same time, few Portuguese authors have demonstrated so profound a knowledge of the vernacular tongue.

Here is what some other authors have demonstrated to me.

The authors demonstrated a simple method for creating a new class of energetic materials.

The author demonstrates her ahistoricism in a second significant manner as well.
