材料:MV UNISOL GroundedWith the engines on stand-by,orders were given to cut the remaining forward lines at 0755 hours,the starboard engine was put on slow astern and the helm to hard a starboard.When the forward lines were cut,the bow was blown off and swung away from the quay under the influence of the wind and,combined with the effect of the engine going astern on the after spring,canted the bow to port,until a heading of North was reached with the vessels stern approximately 15 meters off the dock face.The engines were put to half astern at 0810 hours and with the bow continuing to swing to port,the after back-spring parted with the stern about 20 meters clear of the wharf.Orders were given to cut the remaining 5 stern lines.This was accomplished by 0818 hours,at which time the end of the pier was abeam of the bridge and the vessel was heading in a NWly direction.Both engines were placed to full astern with the shaft turning 80-90 revolutions.As the UNISOL was unable to gain sternway and with high seas at the end of the breakwater,the Pilot feared that the vessels starboard quarter was in danger of striking the breakwater.Hence the engines were stopped at 0827 hours,and orders were given to let go port anchor to 2 shackles in the water,but about 4 shackles ran out before the brake could be fully applied.At 0828 hours,orders were given to shorten up on the anchor cable,the telegraph put on full ahead and the helm to hard to port.When the engines responded at 0829 hours,the anchor chain was seen to be stretched out on the port beam with a great deal of weight on it and the ships head was 220° gyro with the vessel swinging to port.The anchor was hove short to 2 shackles in the water by 0835 hours,and the vessel continued to drift westwards with 80-90 (full ahead) revolutions on the Engine.At this stage,orders were given to pay out the cable,which was paid out to 5 shackles in the water by 0838 hours,but that too failed to arrest the westward drift of the vessel.At 0840 hours,December 7,1983,with the ships head on 180°,the UNISOL grounded on a rocky bottom,forward of the main engine on her star board side,in approximate position 48°20′30.5″ North,64°40′02″West.A spout of water mixed with oil about 60 centimeters in diameter and 2.5-3 meters high above the engine room bottom plating was observed,and at which time the main engines seemed to slow down.问题:the wind was blowing ______.A.WestB.EastC.NorthD.southThe vessel had ______.A.one engineB.two enginesC.three enginesD.fore enginesAccording to the passage, ______.A.The bow of the vessel parted the pier firstB.The stern of the vessel parted the pier firstC.The beam of the vessel parted the pier firstD.It can not tell which part of the vessel parted the pier firstIt can be concluded that ______ .A.the vessel was lying portside along the pierB.the vessel was lying starboardside along the pierC.the vessel was lying at a buoyD.the vessel was anchored请帮忙给出每个问题的正确答案和分析,谢谢!
