Shown above are four men buried up to their necks in the ground.

They
can't move they can only look forward. Between A and B is a brick wall which is completely opaque (they absolutely can't see through it).
They are all aware that each of them is wearing a hat, and that two of them are wearing a black hat, and two of them are wearing a white hat.
They don't know what color THEY are wearing. However, each of them DOES
know where the other three are buried.

In
order to avoid being executed, one of them must call out to the
executioner the color of their hat. If they get it wrong, everyone will
be shot. They can't talk to each other and have only 10 minutes to
figure it out.

After 60 seconds, one of them calls out.

QUESTION: Which one of them calls out? How can he be certain he knows the color of his hat?

Sean
caught a prize fish last weekend. He was going to measure it but
realized that his ruler was not long enough. He was able to measure the
head and discovered that it was 9cm long, he then measured the tail and
found that it was the length of the head plus half the length of the
body. If the body was the length of the head plus the tail, what is the
total length of the fish?
