Cevap

No employee at the Crestview Municipal Library who manages the archival collection is permitted to perform public front-desk duties during morning shifts.
The statement that no employee who manages the archival collection is permitted to perform morning front-desk duties follows directly from chaining the two premises: any archive manager must have completed advanced cataloging training, and anyone who has completed that training is barred from working the morning front desk.

Adım Adım Çözüm

1
Identify and symbolize the first conditional premise.
Manage Archive → Completed Advanced Training
The statement establishes that managing the archival collection guarantees that advanced cataloging training has been completed.
2
Identify and symbolize the second conditional premise.
Completed Advanced Training → NOT Permitted Morning Front-Desk Duties
The universal negative rule establishes that having completed advanced training excludes an employee from morning front-desk duties.
3
Chain the conditional statements together deductively.
Manage Archive → Completed Advanced Training → NOT Permitted Morning Front-Desk Duties, which yields: Manage Archive → NOT Permitted Morning Front-Desk Duties
Transitive property of conditional logic yields the guaranteed deduction.
