材料:While berthed alongside in Tenerife,the cruise ship Arcadia was carrying out a lifeboat drill.One lifeboat was successfully launched and as it was being recovered,the winch hoisting it failed.The lifeboat was still connected to the falls and it dropped back into the sea. To investigate what had happened,the crew had to wind the falls back onto the winch drum.The lifeboat was disconnected while the crew tried to restart the winch.They were unsuccessful because of a fault on the hand crank cutout switch.The crew then attempted to wind the falls back on using the hand crank,but because of the time and effort involved,the cutout switch was bypassed and power restored to speed up the operation.The crank handle was left in place. The winch was started.It began to turn and so too did the handle which hit one of the crew over the head.The investigation found that the winch failed in the first place because the oil used in the winch gearbox was not one recommended.It was too viscose and would have prevented the coupling locking mechanism from operating correctly.问题:It was the fault on the ________ that caused the failure to recover the lift boatA.crank handleB.hand crank cutout switchC.power systemD.fallsIt was the ________ that hit the crewmember on his head.A.fallsB.hand crank cutout switchC.crank handleD.winch drumThe cause of the accident was that ________.A.the oil used in the winch gearbox was too viscoseB.the winch drum was connected with the fallsC.the life boat was too heavyD.the bypass to the cutout switch was misused by the crewThe lesson from this accident is that ________.A.seafaring is not all about facing unforeseen situationsB.it is not necessary to wear hard hats to prevent sore headsC.the wrong oil can not have serious repercussionsD.do not start lifeboat winch motors with the crank handle in place请帮忙给出每个问题的正确答案和分析,谢谢!
