Read the following passage and answer the item that follows. Your answer to this item should be based on the passage only.

An outpatient department that gives every patient the same ten minutes is easy to plan and hard to defend. The straightforward case is done in four and the clock runs on; the complicated one is stopped at ten with the important question half asked. Neither patient is served by the rule, and the queue outside absorbs the difference, because the minutes lost to the first are not transferred to the second. Departments that grade appointments by expected complexity, and hold a reserve of longer slots, report both shorter average waits and fewer follow up visits for the same complaint.

Consider the following statements:

1. Giving every case an identical slot length serves the convenience of scheduling rather than the needs of the cases themselves.

2. A fixed slot system can lengthen queues precisely because it cannot absorb variation between cases.

Which of the statements given above is/are correct?
