Answer:

The humann brain is the most complex organ of all organism. According to a study our brain do many types of calculation for finding a solution of a situation but what it exactly does is undifined till now. To check this you can play a game just think of a railway track on which 4 workers are working and train is coming from behind them fully out of control and you are standing at a track changer lever you can save the 4 person by pulling the lever but on the other track there is also one more parson. So think will you save one person or will save 4. And to make a twist in the game we will play a second round. In the first round we saw only a person on the other track and 4 person on the track on which train was coming. If we interchange that alone person on the other track with your father or any relative, then which one will you save your father or the 4 people. This will help you find how the brain actually works.
