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
这事GWD原题 答案是B 不过我当时遇见的选项和这个不大一样 原文也不大一样
但是专有名字是一样的
原问提到发现沉船变成了两半
但是船的c没有损坏 但是舱门坏掉了 还说舱门是insecure
选项有一个是说c是在船的end 要是沉下去会先撞到
还有一个是说因为youstorm才有那么多水灌进来 不然就算是舱门insecure 也不会的(我选了这个)
终于想起来数学里面最奇怪的一道题
一个班有24(数字不确定 但是已知)名学生
某次考试平均分是84 方差是6 已知成绩落在均数 k standard deviation 范围内的概率是 1-(1/k^2)
【考场上就觉得熟悉 翻了课本 原来就是 Chebyshev's Theorem:the proportion of the data that lies within k standard deviations of the mean is at least 1-(1/k^2) 】
