Explanation:

The Spanish Flu pandemic (1918 - 1919) was a global health crisis. It infected a large portion of the world's population and caused a high number of deaths. In the U.S., it led to approximately 700,000 fatalities. Submarine warfare was more relevant to naval combat in WWI but not the main cause of such a high civilian/military death toll in this time - frame. Battlefield wounds and poison gas were significant in WWI combat but did not account for the massive number of deaths comparable to the pandemic.

Answer:

pandemic.
