The technology developed during World War I resulted in (1) smaller nations becoming part of larger empires after the war
(2) a smaller number of refugees during the war
(3) increased military casualties in battles fought during the war
(4) a slowdown in transportation improvements after the war

As a result of technology developed in WW1, a situation arose where there were (3) increased military casualties in battles fought during the war.

World War 1 technology included:

As a result of these, more people died whenever sides fought as these weapons were much more deadly and efficient at killing.

In conclusion, more casualties resulted from WW1 technologies.

Hey there! I'm happy to help!

Let's look for answers that have to do with technology.

Smaller nations becoming part of larger empires is not really related to new technology, so this answer is not right.

Technology would not have allowed a smaller number of refugees during the war because the main thing that would have allowed a smaller number is more peaceful countries and places to take refuge, not necessarily new technology.

A slowdown in transportation improvements does not make much sense because if technology was improving it should have been easier to improve this.

New technology could have allowed for more military casualties because new and more destructive weapons such as machine guns, flamethrowers, tanks, etc. that would have caused many more people to perish.

Therefore, the answer is 3) increased military causalities in battles fought during the war.

Have a wonderful day!
