Correct Option (C)
The passage explicitly states that habits "simplify the mechanism of life" and "enable us to do a multitude of things automatically." It further elaborates that requiring "fresh and original thought" for every task "would make existence an impossible confusion." This directly implies that habits facilitate daily living by reducing cognitive load and streamlining actions, thereby making life easier to navigate.
Incorrect Options:
- (A) tend to make our lives difficult: This option contradicts the central theme of the passage, which asserts that habits "simplify the mechanism of life" and prevent "impossible confusion," indicating an ease, not difficulty, in living.
- (B) add precision to our lives: While habits may contribute to efficiency, the passage primarily emphasizes their role in simplification and automation to avoid confusion, rather than specifically highlighting the addition of precision as their main benefit.
- (D) tend to mechanize our lives: The passage uses the phrase "simplify the mechanism of life" in a positive context, referring to the automation of routine tasks for practical living. It does not suggest a negative or dehumanizing mechanization, but rather a practical streamlining of activities.
