Historian: We can learn about the medical history of individuals through chemical analysis of their hair. It is likely, for example, that Isaac Newton’s psychological problems were due to mercury poisoning; traces of mercury were found in his hair. Analysis is now being done on a lock of Beethoven’s hair. Although no convincing argument has shown that Beethoven ever had a venereal disease, some people hypothesize that venereal disease caused his deafness. Since mercury was commonly ingested in Beethoven’s time to treat venereal disease, if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct.

Which one of the following is an assumption on which the historian’s argument depends?

A.None of the mercury introduced into the body can be eliminated.
B.Some people in Beethoven’s time did not ingest mercury.
C.Mercury is an effective treatment for venereal disease.
D.Mercury poisoning can cause deafness in people with venereal disease.
E.Beethoven suffered from psychological problems of the same severity as Newton’s.

答案給B
mercury可以treat venereal disease
又假若貝多芬在頭髮中驗到 mercury, 不就表示有venereal disease
而B為何會是assumption, 他們到底有啥關係啊??
腦袋轉轉轉到打結了~~~

題目中假設貝多芬是因為venereal disease導致deaf...
引用證據為若頭髮中有mercury,即成立,因為mercury在當時普遍用來治療venereal disease!!

其assumption為B.有些在那個時代的人並沒有攝取mercury...
若是大家都有攝取mercury,顯見mercury尚有其他功能(應該不會大家都得到venereal disease吧)...那麼驗出mercury不一定代表是患有venereal disease才服用!!因此也就無法確切推導到那個結論了...

[Jessy]

原來B的目的在於排除mercury當作treatment外的其他原因

只有患venereal disease的人才會攝取,
而沒有患有venereal disease(選項中的some people)就不會攝取囉!!

了解了!!

請問選項(C)錯在哪裡?

some people hypothesize that venereal disease caused his deafness. Since mercury was commonly ingested in Beethoven’s time to treat venereal disease, if researchers find a trace of mercury in his hair, we can conclude that this hypothesis is correct.

Conclusion- 若發現貝多芬的hair有mercury，可證明他是服用此物來治療性病

(B) Some people in Beethoven’s time did not ingest mercury. 同時代的人沒有服物此物，表示其他人沒性病
(C) Mercury is an effective treatment for venereal disease
此物有效治療性病，基上有效無效並沒法推出貝多芬是否有性病

我覺得有個"some"怪怪的耶,那是不是表示也還是有人會ingest mercury,而什麼原因我們不曉得,這樣的話前提就不是很清楚了.

雖然認同B 選項應該是答案，但B好像不嚴謹，因為用取非的方式變成..
NOT有些人不攝取mercury→很多人不攝取mercury→仍可推出結論

NOT有些人不攝取mercury→沒有人不攝取(大家都攝取)→推不出結論
