Final answer:
The question involves principles of physics, including mass, force, and distance, in the context of transporting packages safely. All packages should indeed be secured before transport to prevent shifting that can impact control and safety.
Step-by-step explanation:
The question asks whether all packages need to be stowed down before routing a plan. The essence of this consideration is based on the principles of physics, which involve factors such as mass, force, distance, and safety in the context of delivery. Although it does not explicitly reference these principles, it is understood that securing all packages before transport ensures their safety and stability, something which is critical in physics calculations involving movement and force.
In the given scenario, if packages are not properly secured, they may shift during transportation, which could affect the balance and control of the vehicle, especially if sudden maneuvers are required. Furthermore, unsecured packages could lead to injury or damage to goods, which brings in notions of Physics related to momentum and impact force. Therefore, from a practical standpoint rooted in physics, the answer would be A. True; all packages should be stowed down before routing plans are made.
