Answer 2

They say Heidi Klum made pretty good grades.

But that may not be the kind of model you have in mind.

In science or philosophy, a "model" means a generalized, hypothetical representation of a real object or system, intended to aid and promote clear thinking and experimentation related to that object or system.

For example, one might speak of the "systole/diastole model of the circulatory system," meaning the general assumption that blood is circulated by a "pump" (the heart) that works by alternately contracting and relaxing. Or one might refer to the "heat engine model of hurricanes," meaning the concept of a cyclonic storm that forms when air rushes in toward the center of circulation and is forced into a spiral mode of movement.
