• 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?

• One night, a man receives a call from the Police. The Police tell the man that his wife was murdered, and that he should reach the crime scene as soon as possible. The man drops the phone, shocked, and drives 20 minutes to the crime scene. As soon as he reaches the crime scene, the police arrest him for the murder.

How did the police know that he committed the crime?

– The man is not covered in blood. There is no trace of his wife’s blood on him, his car, his possessions, etc.
– The man’s car is not dented from hitting his wife.
– There is no evidence of foul play on the man or his possessions.
– Aliens are not involved. Neither is an unlimited amount of rope, or other unconventional murder weapons.
-These are typical, just perhaps clever detectives. They have no extra-sensory abilities, super strength, mind-reading, gift of flight, x-ray vision, etc.
– The man didn’t say a word when he reached the crime scene. He also didn’t commit any crime on the way to or at the crime scene. The police moved in to arrest him the moment they spotted his car.

• My name sounds like a bird
Whole body is like tongue of a lizard
Am different colors
And I well can be very littered

My energy melts away over time
But not quite like an ice
And when not taken care of
I’ll collect dust and lice

Hint: It’s not a food. And it is quite sticky.
