A study of guppy fish shows that a male guppy will alter its courting patterns in response to feedback from a female guppy. Males with more orange on one side than the other were free to vary which side they showed to a female. Females were drawn o those males with more orange showing, and males tended to show the females their more orange side when courting.
という文章において、
When a model of a female guppy was substituted for the female guppy, male guppies stil lcourted, but were not more likely to show their side with more orange.
とあるとして、ここでのaとtheの使い分けでmodelはどう意味をかえているのでしょうか?
