GMAT邏輯考試假設(shè)題如何解答.

　　下面就讓我們通過(guò)實(shí)例對(duì)考生在GMAT邏輯中的假設(shè)推理的題，容易出現(xiàn)的錯(cuò)誤進(jìn)行解析。

　　無(wú)法找出題干中討論對(duì)象之間的本質(zhì)關(guān)系

　　例：A thorough search of Edgar Allan Poe’s correspondence has turned up not a single letter in which he mentions his reputed morphine addiction. On the basis of this evidence it is safe to say that Poe’s reputation for having been a morphine addict is undeserved and that reports of his supposed addiction are untrue.

　　Which of the following is assumed by the argument above?

　　(A) Reports claiming that Poe was addicted to morphine did not begin to circulate until after his death.

　　(B) None of the reports of Poe’s supposed morphine addiction can be traced to individuals who actually knew Poe.

　　(C) Poe’s income from writing would not have been sufficient to support a morphine addiction

　　(D) Poe would have been unable to carry on an extensive correspondence while under the influence of morphine

　　(E) Fear of the consequences would not have prevented Poe from indicating in his correspondence that he was addicted to morphine.

　　上述題干中提到：一、研究發(fā)現(xiàn)Poe的信件中未提及他患有嗎啡癮;二、Poe沒(méi)有嗎啡癮

　　本題極力在讓考生從“對(duì)Poe的信件調(diào)查[證據(jù)]→Poe未患有嗎啡癮[結(jié)論]”找出兩者的內(nèi)在聯(lián)系，5個(gè)選項(xiàng)中也給出了不同的假設(shè)，那么我們只需通過(guò)反推，來(lái)找出一種能夠使得推理成立的假設(shè)條件即可，但考生往往會(huì)拋開(kāi)“信件調(diào)查”去思考其他使得上述結(jié)論正確的條件(假設(shè))，換句話(huà)說(shuō)考生往往會(huì)認(rèn)為除了對(duì)信件的調(diào)查這樣一個(gè)證據(jù)以外，還可以有其他證據(jù)能夠推出Poe未患有嗎啡癮。

　　通常來(lái)講，當(dāng)一個(gè)推理是從一個(gè)我們已知的，已經(jīng)發(fā)生的事實(shí)推斷出一個(gè)結(jié)論的時(shí)候，我們需要記住的就是，其中的隱含假設(shè)多為這個(gè)結(jié)論的唯一原因，換句話(huà)說(shuō)，在本題中要想對(duì)Poe的信件做出說(shuō)明，那么我們只能假定Poe不會(huì)因害怕后果而不在其信件中提及對(duì)嗎啡的嗜好，本題的正確假設(shè)選項(xiàng)為E.
