C.
A and C are not a universal answer
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.
Answer:
Ok so it says to close read.
Explanation:
Ok so lets begin. I read the story first. So that would be the first thing would'd do. Then, you number the paragraphs. Next, spreate the paragraphs into chunks. Then, reread chunk and circle any unfimilar words. Star any important details. Underline anything that suprised you. Then, after doing that, summerize the chunk and go to the next chunk. The for step one, substitute each choice for the phrase in the text to see which meaning makes sence. Then explain what helped you understand the meaning of "'shined a light on many rock starts' pathes". Hope this helped!
