1.  David, an obvious model for early medieval princes, could have had a special appeal for Charles.

2.  The obvious model is Austria, though getting there may yet take time.

3.  Alcaeus and Sappho are obvious models, but for some poems Horace turned to more recondite sources, in variants of the so-called Asclepiadean and Archilochean metres.

4.  Cartier-Bresson was an obvious model.

5.  Rudolf Nureyev and Margot Fonteyn were the obvious models, although Ms. Jaffe danced the alternate solo that Fonteyn did not.

6.  The obvious model is the NAFTA accord the United States negotiated with Mexico and Canada.

7.  Yet the most obvious model for this piece, oddly enough, is Mahler.
