Eight hours of sleep names a duration. Words such as most and around limit a statement: most does not mean everyone, and around does not mean exactly. This lesson asks you to identify what the speaker says, not to decide how much sleep an individual needs.
Most healthy adults need around seven to nine hours of rest each night.
