GENERAL KNOWLEDGE

Detailed explanation-1: -World War I popularized the use of the machine gun-capable of bringing down row after row of soldiers from a distance on the battlefield. This weapon, along with barbed wire and mines, made movement across open land both difficult and dangerous. Thus trench warfare was born.

Detailed explanation-2: -60% of the battlefield casualties in WWI were caused by artillery shells exploding. Shrapnel wounds were particularly brutal for soldiers. The word ‘shrapnel’ comes from the small lead balls placed in an artillery shell that would spread out over the battlefield when exploded.

Detailed explanation-3: -How Gas Became A Terror Weapon In The First World War. The trench warfare of the Western Front encouraged the development of new weaponry to break the stalemate. Poison gas was one such development. The first significant gas attack occurred at Ypres in April 1915, when the Germans released clouds of poisonous chlorine.
