An economist concluded that Kregg Company deliberately discriminated against people with a history of union affiliation in hiring workers for its new plant. The economist's evidence is that, of the 1,500 people hired to work at the new plant, only 100 had ever belonged to a labor union, whereas in Kregg Company's older plants, a much higher proportion of workers have a history of union affiliation.

9. Which of the following is an assumption on which the economist's argument depends?
(A) None of the people with a history of union affiliation who were hired to work at the new plant were union organizers.
(B) Applicants for jobs at the new plant were not asked by Kregg's recruiters whether they had ever belonged to a labor union.
(C) In the plants of some of Kregg's competitors, the workforce consists predominantly of union members.
(D) The company believes that the cost of running the new plant will be lower if labor unions are not represented in the workforce.
(E) The pool of potential candidates for jobs at the new plant included some people, in addition to those Kregg hired, with a history of union affiliation.

还有一个啊~~谢谢！！

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.
