Final answer:
Operational Risk Management (ORM) should be practiced continuously, hence 'at least seven hours' suggests that its practice extends beyond a fixed hourly schedule, aligning with the notion of consistent application.
Step-by-step explanation:
In reference to the student's question regarding how often Operational Risk Management (ORM) should be practiced, the best answer is not explicitly provided in the context given. However, the nature of ORM implies that it is a continuous process applied to every decision-making process. Therefore, if we were to interpret that ORM must be practiced 24 hours a day, 7 days a week, the closest possible answer would imply that it should be part of all activities during that time frame, rather than being limited to certain hours. Hence, the most logical fill-in-the-blank conclusion would be that ORM should be 'practiced at least seven hours,' as it suggests ORM is an ongoing process that extends beyond a fixed hourly schedule.
