• A man has a medical condition that requires him to take two kinds of pills, call them A and B. The man must take exactly one A pill and exactly one B pill each day, or he will die. The pills are taken by first dissolving them in water.

The man has a jar of A pills and a jar of B pills. One day, as he is about to take his pills, he takes out one A pill from the A jar and puts it in a glass of water. Then he accidentally takes out two B pills from the B jar and puts them in the water. Now, he is in the situation of having a glass of water with three dissolved pills, one A pill and two B pills. Unfortunately, the pills are very expensive, so the thought of throwing out the water with the 3 pills and starting over is out of the question.

How should the man proceed in order to get the right quantity of A and B while not wasting any pills?

• This painting is painted by well known artist Octavio Ocampo, He called it “Calvary”.

Calvary is a painting of hope. Christ’s face is heavy with sorrow as he takes on the sins of the world and makes his incredible sacrifice on the cross. Through the face of Jesus suffering, we can see the crucifixion which is the sacrifice Christ made for all humanity. The middle left side of the painting depicts the sacrifices made by Christian martyrs.
