The Copilot

I am the copilot. I sit on the right.

It's up to me to be quick and bright;

I never talk back for I have regrets,

But I have to remember what the Captain forgets.

I make out the Flight Plan and study the weather,

Pull up the gear, stand by to feather;

Make out the mail forms and do the reporting,

And fly the old crate while the Captain is courting.

I take the readings, adjust the power,

Put on the heaters when we're in a shower;

Tell him where we are on the darkest night,

And do all the bookwork without any light.

I call for my Captain and buy him cokes;

I always laugh at his corny jokes,

And once in awhile when his landings are rusty

I always come through with, "By gosh it's gusty!"

All in all I'm a general stooge,

As I sit on the right of the man I call "Scrooge";

I guess you think that is past understanding,

But maybe some day he will give me a landing.

Riddle

Solution to Question 3: 

Knights, Knaves and Normals

Imagine you are on an island called Texel, with inhabitants that look the same from the outside, but differ in their truthfulness. We distinguish the following types:

Knights, who always tell the truth.

Knaves, who never tell the truth

Normals, who sometimes tell the truth and sometimes lie.

Assume you meet one of these inhabitants, and he tells you: "I'm no Knight". Then, of what type is inhabitant?

 Knight

 Knave

 Normal

 Indeterminable

The Solution:

Normal

An Explanation

A Knight cannot make the statement "I'm no Knight", since this would be a lie and a Knight always tells the truth. A Knave could also not make the statement, since that would be a true statement, and a Knave never tells the truth. A Normal however can say, "I'm no Knight". It is true, and Normals sometimes tell the truth.

Question 4: Color of the Bear

A hunter leaves his cabin early in the morning and walks one mile due south. Here he sees a bear and starts chasing it for one mile due east before he is able to shoot the bear. After shooting the bear, he drags it one mile due north back to his cabin where he started that morning. What color is the bear?
