材料:At 0840 hrs，with the ships head on 180°，the UNISOL grounded on a rocky bottom，forward of the main engine on her starboard side．A spout of water mixed with oil about 60cm in diameter and 2.5-3m high above the engine room bottom plating was observed，and at which time the main engines seemed to slow down．The engine room flooded rapidly and the water level soon reached the electro-magnetic couplings，stopping the main engine．In the meantime，on being apprised of the situation，the Master ordered the evacuation of the engine room，which was successfully carried out under the supervision of the 2/E engineer，and the engine room crew were mustered on the boat deck wearing life jackets．Shortly thereafter，the emergency air cut-off to the engine room and the emergency fuel shut-off were actuated causing the main generator to stop at 0845 hrs．The emergency generator then started up automatically．The starboard anchor was dropped in an attempt to prevent further westward drift．The vessel was by this time being subjected to pounding on the rocks，eventually breaking her back at 0930 hrs after which the violent motion ceased. Evacuation of the vessel commenced at 1045 hrs using 2 SAR helicopters with a Buffalo fixed-wing aircraft in attendance，and was completed at 1220 hours．问题：The main engine was caused to stop by the loss of the function of ________．A.engine room bottom platingB.emergency fuel shut-offC.emergency air cut-offD.electro-magnetic couplingsThe reason that the violent motion of the vessel ceased was that ________．A.the starboard anchor was dropped properly to prevent further westward driftB.the winds and/or seas decreased in a considerable extentC.the vessel was held fast on the grounding rocksD.the vessel's back was brokenThis report is most likely prepared by ________．A.the master of the vesselB.the cargo owners of the vesselC.the shippers of the vesselD.the independent investigator of the accidentThe crew were taken off the vessel by ________．A.air-planesB.helicoptersC.an fixed-wing aircraftD.the boat under the supervision of the 2/E engineer请帮忙给出每个问题的正确答案和分析，谢谢！
