考古題 Form18-4

4. Many pregnant women suffer from vitamin deficiency, but this is frequently not due to vitamin deficiency in their diets; most often it is because they have higher requirements for vitamins than do the rest of the population.

The best criticism of the reasoning in the statement above is that it
(C)fails to employ the same reference group for both uses of the term "vitamin deficiency"
(D)provide insufficient information about the incidence of vitamin deficiency in other groups with high vitamin requirements
(E)uses "higher requirements" in an ambiguous manner

這題答案是C
題目很簡單
可是答案我都感覺沒點到要害
請教CDE
為什麼D 對其他人發生維他命缺乏且高維他命需求的資訊不足
還有E 對高維他命需求定義不明
這兩個為什麼不行啊

再請教C這個答案
意思是說
應該要設一個維他命缺乏的對照組嗎
有點不懂
感謝指教喔...

1. 貼題目的時候 請記得也要貼完整的答案唷 :)

2. 我覺得C是在說 the rest of the population 變成擴大到不只是women 連men也包括進去了 所以是錯誤的
