Question 913 Deck General

The correct answer is B) Lower the stern ramp, raise/open the stern door, turn on ventilation for cargo holds. This sequence is the proper order of actions to be taken prior to loading or discharging cargo on a Ro-Ro (roll-on/roll-off) vessel. The stern ramp must be lowered first to provide access to the cargo holds. Then, the stern door is raised or opened to allow for the movement of cargo. Finally, the ventilation for the cargo holds is turned on to ensure proper air circulation and safety during cargo operations. The other options are incorrect because they do not follow the proper sequence. For example, option A starts with turning on ventilation before lowering the ramp and opening the door, which would not provide access to the cargo holds. Options C and D also have the steps out of the correct order.
