Read the following passage and answer the questions given at the end.
People say that money and physical strength are instruments of power. In olden days, a man with the strongest body was the natural leader of his men. Today, a man of wealth commands great influence in society. If he cannot get what he wants, he will buy it with his money. But we must admit that knowledge is a far greater power than money or physical strength. It is with this power that man controls the oceans and travels across space.
But knowledge does not give brute force alone. It is a power in the moral and intellectual sphere also. It enables man to distinguish between right and wrong, and good and evil. It helps him to meet dangers and difficulties with courage and confidence. But knowledge can be a power for evil also. A country can destroy another country with the help of nuclear weapons. So, knowledge must be used for the good of humanity alone; only then it will prove to be a blessing for mankind. (168)
