材料：During the morning of 2 August 1999 the supply vessel Putford Worker was working cargo at installations in the North Sea. She had completed operations at one installation without incident．At 1110 she approached the second installation and carried out precautionary engine and steering tests．These were satisfactory，and at 1115 the vessel was in position to work cargo．The master was on the bridge at the joystick control；the weather was fine and the sea calm． The first lift was a 10 x 8 container．The deck crew attached the hook of the installations crane to the container，and moved forward to a safe position．The master then noticed that the vessel was moving forward out of position and moved the joystick to counteract the ahead movement．He then saw that the port propeller was indicating full ahead pitch，so changed from joystick to manual pitch controls and promptly put them to full astern．This did not prevent the vessel moving ahead so far that the attached container be dragged over the stern and into the sea. Placing the manual pitch controls to zero then caused both propellers to return to neutral．Control of the vessel was regained，and the problem did not immediately re-occur．Later tests and inspections by specialist control engineers and the propeller manufacturers showed no fault with the control systems or the port propeller．However，some wear was found in the feedback linkages on the control system of the starboard propeller．This was rectified，and manoeuvring tests completed satisfactorily．问题：In this passage the supply vessel is ________．A.one that supplies fuel oils to other deep sea vesselsB.one that supplies stores to other deep sea vesselsC.a tug boatD.smaller container vesselThe joystick is a device ________．A.controlling ruddersB.controlling shore cranesC.controlling the operation of cargoesD.controlling the propellersOn noticing that the vessel was moving forward out of position，the master ________．A.moved the joystick forward to go together with the ahead movementB.moved the shore crane to go aftwardC.made the container move aftward by operating the joystickD.operated the joystick to control the vessel and move her aftwardIt is clearly demonstrated that ________．A.the testing of engines and steering before working cargo at an installation is an important precautionB.the testing of engines and steering before working cargo at an installation was not followed by Putford WorkerC.there is no value of moving the deck crew clear once a lift is attachedD.had the deck crew not bothered to move clear from，the consequences could have been avoided请帮忙给出每个问题的正确答案和分析，谢谢！
