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 dipends?

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.

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

答案是B, 可是我原文都看不太懂

船身断裂的两段靠得很近,而暴风会使得分裂的部分相隔很远(船在沉之前已经断裂,同时暴风令到分裂的部分隔得很远),所以,沉没不是由断裂造成的

前提:水底的currents不会把断裂的部分再次推近
