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

There are a number of hidden faces in the picture, can you spot the total number of faces in the picture?

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.

• Tricky question, be attentive-
There are four airplanes flying in four different directions. Each of the plane navigates a straight line at a constant speed. Please keep in mind that none of the two planes are flying parallel with each other. They began flying at the same time long time ago. Sometimes, even a collision takes place but the strong build, makes the planes continue with the journey. But even the sturdy built can only survive two collisions and after that the plane will crash.

Out of the six possible collisions, five have already taken place (do note that the collisions did not involve more than two planes at one time). Two planes have already crashed. What will be the fate of the remaining two planes?
