Final answer:
Fred's property is the servient tenement because it is subjected to an easement allowing Gina to drive across it to reach her house.
Step-by-step explanation:
In the scenario where Gina has an easement to drive across her neighbor Fred's property to get to her house, the servient tenement is Fred's property. The servient tenement refers to the parcel of land over which the easement is granted. This means that Fred's land bears the burden of the easement, allowing Gina, who holds the easement, to use a part of it for access to her own property, which is known as the dominant tenement.
