Hastings‘ contracture is a disorder of the connective tissue in one or both hands, most commonly causing loss of mobility. 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. Clearly, therefore, a single surgical treatment of Hastings' contracture is often ineffective at providing long-term correction of the disorder.

Which of the following, if true, most seriously weakens the argument?
(A) The medical-insurance claims did not specie whether the surgery was on the patient's right or left hand.
(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.
(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.
(E) Many people who have Hastings' contracture choose to tolerate its effects rather than undergo the risks of surgery.

原题逻辑：因为medical-insurance claims that 百分之30的患者做过单手手术后病情又复发了（就是那个disorder又出现了），所以 a single surgical treatment of Hastings' contracture 效率低下。

正确选项说的是medical-insurance claims 没有说是手术是对哪只手做的。
这很明显是在weaken，because 选项等于提供了一种可能：那百分之30患病的是因为做手术没有对正确的那一只手（具体是哪一只文中没说，也不重要，我是怕你疑惑）做才导致复发的，而不是因为这种手术方法效率低！

这种削弱方式属于削弱论据，西安新东方胡文宁称之为 他因削弱！！
