Read the following passage carefully and answer the questions on it

. 
      The history of warfare reveals that man has come a long way. In the beginning man contented him self with simple hand-hurled missiles. Man threw the stone at other animals and. in warfare, at his enemies. Destruction was minimal, as this was determined by the size and roughness of the stone and the energy of the thrower. Even when man later invented the catapult, destruction was only slightly higher. The primitive catapult was made out of a tough rope at one end of which was tied a big stone. Its most limiting factor was that such a missile, no matter how strong the force behind it, could kill only one person at a time. 
      Things were relatively easier for the assailant with the invention of the bow and arrow. For the first time, man utilized very little strength to bring down his enemy, even at a fairly distant position. The size of the bow, the elasticity of its string, and the sharpness of the arrow, much more than the crude energy of the thrower, determined how far and fast the arrow traveled. The weapon became even more significant when man later learnt to fix a sharp metal to the tip of the arrow. And when that metal was dyed in highly lethal poison, it became even more effective in killing a man. 
      With the coming of metal, farm implements were developed. But man soon turned some of these, especially the machete. into weapons of combat. The sword is thus a very close cousin of the machete. Used in combat, the sword, especially when carried by a very skillful fighter on a horse, could wreak far more havoc than the bow and arrow. It is hence understandable that the foremost conquerors of the classical period, from Alexander the Great to Julius Caesar, used this simple hand-borne instrument of combat. And this, in its simple turn with the invention of the gun and the bullet. The arrival of the gun introduced destruction of human lives at an unprecedented rate with even the most elementary gun. In the hands of foot soldiers, it became possible to count casualties in hundreds in a single encounter. With practically no physical effort, apart from the moving of a finger on the trigger, the highly lethal bullet is sent through the barrel at a speed much faster than that of sound. The enemy, at a considerable distance, may thus be brought down without even hearing the sound of the shooting or seeing his assailant.

      The development of grenades, bombs, missiles, nuclear and chemical war-heads have made all previous weapons appear little more than toys. With bombs delivered by fast-flying airplanes, and nuclear or chemical war-heads borne to their distant destinations by unnamed missiles, destruction of cities and, in fact, of whole countries within a matter of hours is now a great possibility. Today, man doesn't need to be physically present to haul the stone, or throw the spear, or send the arrow. The missile has now replaced all these, and it does not need to be physically sent by an individual. Electronics and computers do the launching, and men die in hundreds of thousands.
