Naiven and Host with the Same Skill

So I have a relatively simple question. Suppose a Naiven with Administration 4 is put into a host with Administration 2, what happens? Does the New Valen simply use the higher of the two skills? Does he combine them? Average them?

I haven’t been able to find an answer in the book, and I would like to know what the intent was.

Use the better of the two.
