Answer:
The populace of Fahrenheit 451 were unstable emotionally.
Step-by-step explanation:
Fahrenheit 451 is written by Ray Bradbury. The novel is dystopian; it tells of the future of American society, when books in the society will be banned and burned whenever seen anywhere.
The line given above reveals the unstable emotional state of the population of the society.
Mildred, the wife of Guy Montag, was emotional unstable. She has tried to attempt sui-cide several times. The only way for her to avoid problems in her life was watching television.
The statement made by the machine operators suggests that the people in Montag's society were emotional unstable. The statement that the operator gets such cases as Mildred, nine or ten a night, tells that most of the population in that society suffered from depression. They were unhappy and unstable emotionally.
