材料：Condor a catamaran vessel operating between the Channel Islands and France．The vessel has two main engines in each hull．All propulsion units are duplicated，with each set independent from the other．Shortly after leaving St Helier，Jersey，with 31 passengers and 18 crew，the fire alarm sounded indicating a fire in the starboard engine room．This was confirmed by the closed circuit television surveillance system which showed flames in the vicinity of the starboard outer main engine．The vessel was immediately stopped，all machinery in the starboard engine room was stopped and the fuel supplies shut down．Jersey Radio was informed of the situation two minutes after the alarm sounded. After closing all ventilation openings and accounting for all personnel，halon fire smothering gas was released into the starboard engine room．This was done five minutes after the fire alarm first sounded. The crew maintained boundary cooling and intermittently operated the sprinkler system to the affected space．Twenty minutes after the alarm sounded the situation was considered to be under control．Using the port main engines the vessel returned to St Helier where assistance was available from shore based emergency services．问题：Condor has two ________ main engines．A.combinedB.independentC.coupleD.doubleThe fire accident happened in ________．A.both the engine roomsB.neither engine roomsC.the port engine roomD.the starboard engine roomThe fire was mainly extinguished with ________．A.waterB.chemical agentC.foamD.powderIt can be concluded that ________．A.no officials from any authority know the accident after it happenedB.some officials ashore must have learnt the accident at very beginningC.there must be casualties even they were not mentioned in the reportD.fire is not dangerous on board vessel请帮忙给出每个问题的正确答案和分析，谢谢！
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！
