Two Tests - IQ and Jurisprudential Orientation

A while ago, I promised a Japanese IQ test. Unfortunately the website hosting it seems down - whether permanently or merely temporary I don't know.

In any case, it's one you can do without flashy graphics. It's one of those 'ferrying people across a river' type things, with some restrictions on who can go where.

There's a family of six (Mother, Father, two sons, two daughters) and a policeman and thief who must all cross a river on a two-person raft. The following rules apply:
Only 2 persons on the raft at a time.
The father cannot stay with any of the daughters without their mother's presence.
The mother cannot stay with any of the sons without their father's presence.
The thief cannot stay with any family member if the Policeman is not there.
Only the Father, the Mother and the Policeman know how to operate the raft.

The solution is available here.

Another interesting test I found today is one that determines your jurisprudential orientation - i.e. whether you're a positivist, Dworkinian, etc. It's available here.

For the record, I think I'm confused. Maybe more regular attendance at the Jurisprudence Discussion Group in question will help...
