The cause of the wreck of the ship Edmund Fitzgeraid in a severe storm on lake Superior is still unknown , when the sunken wreckage of the vessel was found, searchers discovered the hull in two pieces lying close together, The storm’s violent waves would have caused separate pieces floating even briefly on the surface to drift apart. Therefore, the breakup of the null can be ruled out as the cause of the sinking.
B.Under water currents at the time of the storm did not move the separated pieces of the hull together again. 题目是说发现的沉船碎片是靠在一起的，风暴将会使碎片分开。所以船身破碎的原因不可能是因为船沉了。不明白根据前面的怎么可以退出这个结论，要推也应该是沉船的原因不是因为风暴啊
