OG10的16题
                                                      OG16. During the Second World War, about 375,000 civilians died in the United States
and about 408,000 members of the United States
armed forces died overseas. On the basis the those figures, it can be concluded that it was not much more dangerous to be overseas in the armed
forces during the Second World War than it was to stay at home as a civilian.
Which of the following would reveal most clearly the absurdity of the conclusion drawn above?
A. Counting deaths among members of the armed forces who served in the United
            State
in addition to deaths among members of the armed forces serving overseas
B. Expressing the difference between the numbers of deaths among civilians and members
of the armed forces as a percentage of the total number of deaths
C. Separating deaths caused by accidents during service in the armed forces from deaths
caused by combat injuries
D. Comparing death rates per thousand members of each group rather than comparing total
numbers of deaths
E. Comparing deaths caused by accidents in the United States
to deaths caused by combat in the armed forces

答案是D，可是我怎么觉得D说反了呢，题干的错误应该是比较了死亡人数，没有比较死亡率，所以应该是Comparing total numbers of deaths rather than comparing death rates per thousand members of each group 才对呀？？请指教！

说实话，我也这么认为。。。害得我选了没怎么看明白意思的B。

我也是！不明白B什么意思，不过觉得好像也说反了。。。

题干简化：二战中美国公民死了37500，大兵死了40800.结论：到海外当兵并不比在国内当老百姓危险多少。
问削弱。

首先很明显，如果美国公民3亿，就死了37500，而大兵就50000，却死了40800，则肯定削弱。而事实也基本如此：公民比大兵的基数要多很多。

A对比国内和海外服役的死亡人数。与公民死亡无关。
B将公民和大兵死亡人数的不同表示为公民死亡/总死亡人数[即37500/(37500+40800)]与大兵死亡/总死亡人数[即40800/(40800+37500)]的区别。此对比不能说明那个更危险，因为这和直接比较死亡人数是一样的。
C将服役的因为事故死亡和战死的大兵分开。与题干无关。
D比较每千人死亡率而不是比较死亡人数。显然这能说明做公民更安全。
E将在美国事故死亡的人数与战死的大兵数相比。不能说明二战中作公民安全还是当兵安全~
多多指教。

我觉得你解释的B是对的。对于D，文章的错误应该是比较了死亡数量而不是死亡率，所以D说反了呀？?

比较死亡率是没错的，但是如果你用在总人数作为分母，在美国国内死的人和在海外战场死的人都用这一个分母，这和比较死亡人数就没有区别了。所以B肯定是错的。
而D的意思才是两个地方分别的死亡率，两个地方的死亡人数分别占两个地方的总人数的比重。

题目是问采取如下哪个讲能揭示题干的错误。Which of the following would reveal most clearly the absurdity of the conclusion drawn above?
如你所说“题干的错误应该是比较了死亡人数，没有比较死亡率”，所以选项采取正确的方法“比较死亡率”将揭示错误。
