标题: GWD TN22 Q3 求助
搜了下,似乎没有这道题的讨论,
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 hull can be ruled out as the cause of the sinking.
Which of the following is an assumption on which the argument depends?
A. Ships as large as the Edmund Fitzgerald rarely sink except in the most violent weather.
B. Under water currents at the time of the storm did not move the separated pieces of the hull together again.
C. Pieces of the hull would have sunk more quickly than the intact hull would have
D. The waves of the storm were not violent enough to have caused the breakup
E. If the ship broke up before sinking , the pieces of the hull would not have remained on the surface for very long
答案B,但是我没有太看懂这道题说什么,劳烦大家给我解释下,多谢啦~

船体失踪,失踪后的船被发现后是断开的,而且是两半连在一起的,水的冲击力应该把两半冲开,而不是在一起被发现,所以得出结论。在沉下之后压力压开的,不是冲断的
b假设是,冲断的话是不会把两个冲开,又冲到一起的

大概意思:某船在一个严重的风暴中沉于湖中,原因未知。当沉船碎片被找到时,船体分成两半躺在一起。风暴的猛烈波浪应该使分离的碎片漂移开。因此,船体的崩裂不能成为沉没的原因。

最后两句话的就是说既然风浪会分离开船体碎片,而实际船体碎片躺在一起,那么船的沉没不是由于船体崩裂后造成的。

B的意思就是(虽然风浪会分离开船体碎片)风浪不会使分开的碎片又飘到一块来。
