Even with the lack of a reference document, the Korean War that was fought by communist-North Korea and US-South Korea was devastating because of the fact that many of the war-families were forced to split their paths.
Explanation:
Every war is a tragedy, people are unnecessarily killed in it is a tragedy, a war that ends with a pause where no one wins or loses something but their lives is also a tragedy.
The war ended on the 38th parallel, when the South was occupied by North Korea.
After 3 years and more than 2 million deaths, the front line still ended up moving roughly around the 38th parallel.
Number 3 would be the only logical choice in my opinion because everything else would be in a narrative or story of some sort. Expository essays are exclusively informational.
