Patient: Doctor, I read an article that claimed that the first few hours after birth are very important to establishing a mother-infant bond, which is the first step in building a healthy relationship. Can you assure me that my relationship with my baby has not been permanently harmed by our separation for several days after his birth?

Physician: Your relationship with your child has not been harmed by the separation. Mother-infant bonding is not like an “instant glue” that cements your relationship forever. Having your infant with you during the period immediately after birth does give your relationship a head start, but many factors are involved in building a strong and lasting relationship between a mother and her child.

(C) A strong and lasting relationship is necessary for mother-infant bonding.

(D) Where immediate mother-infant bonding takes place, a strong and lasting relationship between a mother and her child will be assured.

(D) Most people in company management believe that the workers already have too much control over their work.

8. Dr. Sheila Porter plans to run an experiment using nursing students. Each student will be shown either a pleasant nature film or a disturbing horror film. Each student will be observed by someone who—looking only at the student’s facial expressions—must ascertain which film is being shown. Students shown the horror movie are told to hide their feelings in order to convince the observer that they are watching a pleasant film. Dr. Porter hypothesizes that all the students in the experiment who are convincing will be among the best at working with patients. The hypothesis will be tested by comparing the convincing students and unconvincing students in terms of their performance with patents.

Which one of the following incidents best illustrates Dr. Porter’s hypothesis?

(A) Niles, the most convincing student in the experiment, later went on to become a physician.

(B) After graduating, Yoshiro, a nursing student who was convincing in the experiment, helped care for Bram, a patient at a hospital. Bram recovered from his operation.

(C) After graduating, Kim, a nursing student in the experiment who watched the nature film, was removed from the staff of a hospital for unacceptable performance in patient care.

(D) Daria, a nursing student who was convincing in the experiment, later received “A’s” in those classes in which working with patients in a teaching hospital was the sole basis of her grades.

(E) Marite, a nursing student who was not convincing in the experiment, later quit nursing school.

9. Those who think with a hierarchical mentality strive for situations in which their side is dominant and the other side is submissive.

10. It has always been difficult to understand the basis of politics in the People’s Republic of China. Because the system is effectively closed, it is impossible to know with any degree of confidence who is allied with whom and for what reasons.

It is legitimate to conclude, therefore, that China has a factional political system.

(A) All open political systems are factional political systems.

(B) All factional political systems are closed political systems.

(D) China’s political system is more open than many existing factional political systems.

(E) China’s political system is more closed than all existing factional political systems.
