This is a test that a chinese company uses for preemployment, you have two minutes to solve the problem.

Here are the rules in english:

There is a single mother with two daughters, and a single father with two sons, and a policeman who has a criminal in custody. You must follow the rules below to get them across a river. The following rules apply:

- Everybody has to cross the river.

- Only 2 persons on the raft at one 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 (stripe shirt) 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.

Read these directions and then click on the link below:

-To start click on the big blue circle on the right (ignore the other two blue buttons).

-To move the people click on them.

-To move the raft click on the pole on the opposite side of the river.

Right at four minutes. I liked that. Had to go and do it twice. Think I'll try more of them.
