Final answer:
World War I made the Spanish Flu worse because of the quick spread of the disease among the soldiers who were already weakened from the war and were moving around the globe, along with the increased strain on medical resources.
Step-by-step explanation:
World War I exacerbated the effects of the Spanish Flu due to a number of different factors. Firstly, the close quarters and massive troop movements of the war hastened the spread of the disease. Soldiers stationed in the crowded trenches and on transport ships provided ideal conditions for the virus to spread quickly. Secondly, many soldiers were already weakened from the stresses and injuries of war, which made them more susceptible to the illness. Lastly, the chaotic state of global healthcare highlighted by war's monopolization of medical resources also aggravated the situation, leading to the intense impact of the Spanish Flu.
