Final answer:
The national legislature decided to adjourn until the epidemic was over in 1918 during the flu pandemic.
Step-by-step explanation:
The national legislature decided to adjourn until the epidemic was over in 1918 during the flu pandemic. The world was dealing with the flu pandemic of 1918-1920, which infected about one-third of the world's population and killed tens of millions of people. Schools and theaters were closed, public activities were canceled, and people were encouraged to wear masks and limit their movement until the crisis had passed. By early 1920, the flu had stopped spreading, and people were able to return to their pre-pandemic lives.
