Hello. Although you showed the book to which the question refers, you did not say which incident the question refers to, as there are many incidents covered in the book. This makes it impossible for your question to be answered, but I will try to help in the best possible way.
The main factor that points to the transition from old forms of war to new forms of war during the first world war was the use of technologies, mainly those driven by the industrial revolution, which gave the army a warlike power never seen before and allowed each army had access to fighter planes, tanks, submarines, toxic gases and others that did not exist in previous wars and that caused much greater destruction.
B Because its your fault if you don't read it and
When visits the witches a second time, they say that only when Birnam wood marches towards the castle and only man not born of woman can kill him, it's like a confident boost because these things seem impossible.However, the woods look like they move as an army approaches Macbeth's castle, and Macduff (who he is warned of) was cut from his mother's stomach, not physically born.
Hope this helps!<span />
