材料：At 1100 UTC on 28 May 2003，the container vessel PO Nedlloyd Vespucci and the yacht Wahkuna collided in the English Channel in poor visibility．Each vessel had detected the other by radar when at a range of about 6 miles．The container ship was on a course of 255°（T）at a speed of 25 knots．The yacht was on the port bow of the container ship on a course of 012°（C）at a speed of 7.5 knots，and was due to pass about 8 cables ahead of the container ship．The skipper of the yacht，however，incorrectly estimated from his radar display that PO Nedlloyd Vespucci was passing 1.5 miles ahead of Wahkuna，and reduced speed by disengaging his engine．This action，which also resulted in a substantial alteration in the yachts heading as it lost steerage，put the two vessels on a collision course．The actions of the yacht，the CPA of which now appeared as 2 cables to port on ARPA，concerned and confused the master of PO Nedlloyd Vespucci，but he was reluctant to take any manoeuvring action because he was uncertain of what the yacht would do next．Minutes later，the vessels collided and the bulbous bow of PO Nedlloyd Vespucci struck the forward part of Wahkunas hull，demolishing the first 3m of her hull and dismasting her．Despite having sent a lookout to the port bridge wing，the master of the container ship was not aware that a collision had occurred，and continued on passage．The yacht crew had to abandon to a liferaft，where they stayed for 5.5 hours before being rescued.问题：In the situation referred to in this massage，the speed of PO Nedlloyd Vespucci ________．A.was too fastB.was too slowC.was a safe oneD.could not be determined if safe or notThe bridge resource management on board P&O Nedlloyd Vespucci ________．A.was efficientB.was poorC.was too strict comparing with other shipsD.could not be determined if efficient or poorIt can be concluded that ________ failed to keep an effective radar lookout．A.P&O Nedlloyd VespucciB.WahkunaC.both P&O Nedlloyd Vespucci and WahkunaD.neither P&O Nedlloyd Vespucci nor WahkunaIt appears that ________ was not a factor contributing to the collision．A.The inability of the yacht skipper to use radar effectivelyB.Acceptance by the master of the container ship of a small passing distanceC.Over-confidence in the accuracy of ARPA by the master of the container shipD.lack guidance to assist in determining a safe speed in restricted visibility请帮忙给出每个问题的正确答案和分析，谢谢！
