一道GRE邏輯題不會(huì )

Hastings‘ contracture is a disorder of the connective tissue in one or both hands, most commonly causing loss of mobility. H痙攣是一只或者兩只手組織的連接錯位，經(jīng)常會(huì )導致活動(dòng)不便。A survey of thousands of medical-insurance claims found that over 30 percent of people who had one hand operated on for Hastings'contracture underwent surgery a second time for this disorder within three years.一項研究了上千份的醫療保險索賠單的調查發(fā)現，超過(guò)百分之三十的人有一只手進(jìn)行過(guò)H痙攣的手術(shù)，并且在三年內進(jìn)行過(guò)兩次。 Clearly, therefore, a single surgical treatment of Hastings' contracture is often ineffective at providing long-term correction of the disorder很明顯的，因此，對于H痙攣，一次手術(shù)治療不能保證其長(cháng)期的錯位糾正。

Which of the following, if true, most seriously weakens the argument?下列如果是真的，哪個(gè)最能削弱論點(diǎn)。

(A) The medical-insurance claims did not specie whether the surgery was on the patient's right or left hand. 醫療保險索賠沒(méi)有明確出到底是病人的左手還是右手做過(guò)手術(shù)。(B) The surgical techniques used to treat Hastings' contracture are identical to those used successfully to treat certain work-related injuries to the hand. (C) A separate survey found that 90 percent of patients operated on for Hastings' contracture report increased hand mobility within one month after the surgery.另一份研究發(fā)現90%的病人接受過(guò)H痙攣手術(shù)在手術(shù)后1個(gè)月內手的痙攣有改善。 (D) All of the patients in the survey were required by their insurance companies to seek a second opinion from a qualified surgeon before undergoing the operation.所有調查的病人，在進(jìn)行手術(shù)前，保險公司都要求他們向優(yōu)秀的外科醫生詢(xún)問(wèn)建議。 (E) Many people who have Hastings' contracture choose to tolerate its effects rather than undergo the risks of surgery.

答案是A，CD為何不對呢？排除它因？

個(gè)人覺(jué)得，選A是因為有可能那百分之30的人都是雙手痙攣，所以第一次手術(shù)是左手，第二次是右手，再說(shuō)以，結論就不能說(shuō)，一次手術(shù)是不能長(cháng)期有效的。

C項，1個(gè)月內有改善，但是沒(méi)有說(shuō)之后怎么樣，有可能三年內還要繼續做手術(shù)，所以不影響結論：一次手術(shù)不能長(cháng)期有效。

D項，其實(shí)我覺(jué)得這完全不會(huì )影響結論啊~

可以交流一下啦，都是個(gè)人意見(jiàn)

真的是很難的題
