Q3: GWD32-Q1
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. （后两句没看懂）

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

额， 原文最后的结论好像是“船断了并不是船沉的原因”

WesternCder

文中根据残骸中船体断裂而没有分开推断出当时船体只是由于船体断裂而不是遭遇暴浪而沉没的，因为大浪会使船体断开后瞬间分开很远。而单纯的船身断裂沉没会离得很近。
但是，如果当时就遭遇了大浪船身分开很远了，然后又根据B取非，水流又把已经沉没离得很远的船身吹到一起离的很近，那么就削弱了结论说是由于断裂而造成的结果。取非削弱，正确答案。

那个应该是打错了，我觉得应该是HULL，不是null，最后一句那个词

我认为，就是说研究人员发现船身一分为二但是靠在一起，而通常风暴会将船身弄断而二者会分开，因为没分开，所以断裂的船身就不是沉船的原因，差不多就是这个意思。基于的假设就是水流不会将分开的船身再冲到一起去。
