The level of noise in decibels (n) that is permitted during the night in the United Kingdom can be described as n ≤ 24. What does that mean?

A: noise made at night is permitted to be louder than 24 decibels
B: noise, louder than 24 decibels is not permitted at night
C: noise made at night is permitted to be 24 decibels or louder.
D: noise made at night must be softer than 24 decibels

D: noise made at night must be softer than 24 decibels

Are you completely sure that is correct? Can I trust you?

Yes, you can trust me. The statement n ≤ 24 means that the noise level must be equal to or less than 24 decibels, so the correct statement is that noise made at night must be softer than 24 decibels.

Are you very sure?

Yes, I am very sure that the correct interpretation of n ≤ 24 in this context is that noise made at night must be softer than 24 decibels.
