Answer:
15-19 million
Step-by-step explanation:
The exact number of people who died in World War I is difficult to determine due to the scale and complexity of the conflict. However, it is estimated that the total number of military and civilian deaths caused by the war ranges from around 15 to 19 million.
This figure includes both combat-related deaths and civilian casualties resulting from the war's direct and indirect effects, such as disease, famine, and other hardships. The casualties were suffered by multiple countries involved in the war, including soldiers from the Allied Powers (such as the United Kingdom, France, and Russia) and the Central Powers (such as Germany, Austria-Hungary, and the Ottoman Empire).
Please note that casualty estimates can vary depending on different sources and methodologies used for calculations.
