True. The first world war was the first war in which mechanized warfare was prevalent on both sides. The advanced technologies of the powers meant that they could cause more destruction than ever before. Consequently, the causalities for WWI were the highest ever up to that point in time. <span />

*HOPE I HELPED!*
Answer with Explanation:
People risked their own lives just to stay alive in war time because of their "political ideology." It was common for people to go to war, especially men, because it was deemed important in order to have<u> social order in the society.</u> This was also partly because of "pride" and "patriotism" to one's country which was common long time ago. They risked their own lives, not because they wanted to live but because <em>they wanted their families to be protected and to continue living.</em> Besides this, there were also laws<em> (the draft)</em> which strictly orders men to join the war whether they like it or not.<em> </em>
The statement that best explains why the transcontinental railrold took several years to build is digging through the mountains was very difficult, and the long winters hampered workers' ability to make progress. The foothills of Sierra Nevada, the winter snowtorms, shortage of reliable labor and increasing need for tunneling hampered the progress as they went higher in the mountains.
The answer to this really depends on what prism you are viewing it from?
As a globe, we are pretty opposed to imperialism these days. China has started to dabble a little more in the South China Sea but we mostly have our nation states and there isn't really a lot of movement.
That was not the case at the time of annexation.
So, is it ethical to subsume a sovereign nation? No
Was it strategically justifiable at the time? Yes. If the United States had not annexed Hawaii, the Empire of Japan likely would have stepped in.
Hawaii has enormous strategic value and was then justifiable at the time of annexation.
That being said, and I hope this is an obvious statement, imperialism is not a good thing and is ethically problematic.
