12. “Though they soon will, patients should not have a legal right to see their medical records. As a doctor, I see two reasons for this. First, giving them access will be time-wasting because it will significantly reduce the amount of time that medical staff can spend on more important duties, by forcing them to retrieve and return files. Second, if my experience is anything to go by, no patients are going to ask for access to their records anyway.”

Which one of the following, if true, establishes that the doctor’s second reason does not cancel out the first?

(A) The new law will require that doctors, when seeing a patient in their office, must be ready to produce the patient’s records immediately, not just ready to retrieve them.

(B) The task of retrieving and returning files would fall to the lowest-paid member of a doctor’s office staff.

(C) Any patients who asked to see their medical records would also insist on having details they did not understand explained to them.

(D) The new law does not rule out that doctors may charge patients for extra expenses incurred specifically in order to comply with the new law.

(E) Some doctors have all allowing their patients access to their medical records, but those doctors’ patients took no advantage of this policy.

这题题目是说, establishes that the doctor’s second reason does not cancel out the first这句是什么意思?答案A

15. In a large residential building, there is a rule that no pets are allowed. A group of pet lovers tried to change that rule but failed. The rule-changing procedure outlined in the building’s regulations states that only if a group of tenants can obtain the signatures of 10 percent of the tenants on a petition to change a rule will the proposed change be put to a majority vote of all the tenants in the building. It follows that the pet lovers were voted down on their proposal by the majority of the tenants.

The argument depends on which one of the following assumptions?

(A) The pet lovers succeeded in obtaining the signatures of 10 percent of the tenants on their petition.

(B) The signatures of less than 10 percent of the tenants were obtained on the pet lovers’ petition.

(C) Ninety percent of the tenants are against changing the rule forbidding pets.

(D) The support of 10 percent of the tenants for a rule change ensures that the rule change will be adopted.

(E) The failure of the pet lovers to obtain the signatures of 10 percent of the tenants on their petition for a rule change ensures that the rule change will be voted down by a majority of the tenants.
