What must be ensured in the galley literature pocket before every takeoff and landing?

In the context of Southwest Airlines flight safety procedures, it is critical to ensure that the galley literature pocket contains only planned emergency checklists before every takeoff and landing. This ensures that the flight attendants have immediate access to the necessary emergency procedures in the event of an incident. The presence of only the emergency checklists helps avoid confusion or distractions that could arise from other materials, allowing the flight crew to focus solely on safety protocols during these critical phases of flight.

The other options, while they may seem reasonable, do not align with the primary focus of safety and emergency preparedness required in the galley literature pocket. Ensuring that this pocket is solely dedicated to emergency checklists reinforces the importance of being well-prepared and organized for any potential situation that may arise during takeoff or landing.
