Task: Question Answering
Input (English): passage: The traditional American business hours are 9:00 a.m. to 5:00 p.m., Monday to Friday, representing a workweek of five eight-hour days comprising 40 hours in total. These are the origin of the phrase 9-to-5, used to describe a conventional and possibly tedious job. Negatively used, it connotes a tedious or unremarkable occupation. The phrase also indicates that a person is an employee, usually in a large company, rather than an entrepreneur or self-employed. More neutrally, it connotes a job with stable hours and low career risk, but still a position of subordinate employment. The actual time at work often varies between 35 and 48 hours in practice due to the inclusion, or lack of inclusion, of breaks. In many traditional white collar positions, employees were required to be in the office during these hours to take orders from the bosses, hence the relationship between this phrase and subordination. Workplace hours have become more flexible, but the phrase is still commonly used.
 question: is 9 to 5 a 40 hour week?
Output (English): Yes
