I make you weak at the worst of all times.
I keepyou safe, I keepyou fine.
I make your hands sweat, and your heart grow cold,
I visit the weak, but seldom the bold.
What am I?
I am the reason you run, because I allow it. I am the reason you scream. I am the cause of all your pain. I am a cage from which you will never be free.
You are on an island in the middle of a lake. The lake is in a remote part of the country and there has never been a bridge connecting the island to the mainland. Every day a tractor and wagon gives hay rides around the island. Puzzled as to how the tractor had gotten onto the island, you ask around and find out that the tractor was not transported to the island by boat or by air. Nor was it built on the island. Explain how the tractor got there?
In a recreational activity, you are given four different jars of 2 liters, 4 liters, 6 liters and 8 liters respectively with an unlimited water supply. Then you are asked to measure exactly 5 liters of water using them.
How will you do it?
