Super Sleuth Test #2
Lt. Columbo was
cruising in his boat when he came to the Isle of Deceit, a place
where the natives always lie and the visitors always tell the
truth. As Lt. Columbo drew near, he saw 3 girls getting into
a fishing boat on the shore. He asked them, "Are you
natives or visitors?" The first girl called out, but
the Lieutenant hadn't turned off his motor, so he didn't hear the
reply. Lt. Columbo shouted his question to the second girl,
and this time she answered saying, "She said she was a
visitor and so am I." The third girl on shore quickly
shouted, "That's not true, these girls are natives, but I am
a visitor."
Lt. Columbo
immediately knew who was a native and who was a visitor, from
their responses. How could he know this from what they were
telling him?
