OG CR 116

GMAT初心者です。OGの解説を読んでも納得できないので、どなたかご説明頂ければ助かります。

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 of 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 States 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

正解はDですが、私はBにしてしまいました。
問題文が読めていないのかもしれませんが、答えとなる選択肢は文章の欠点を指摘するものとして答えを選びました。そこで正解のDですが、「死者全体で比較するのではなく、各グループにおける1000人あたりの死者を比較すること」と読めますが、これでは本来やるべきことを示唆しているようにしか思えないのですが...

その点Bの「民間人と軍人の死者を全体の死者の割合として表していること」は答えとしていいと思いました。

よろしくお願いします。
