Question 4

A public-service advertisement advises that people who have consumed alcohol should not drive until they can do so safely. In a hospital study, however, subjects questioned immediately after they consumed alcohol underestimated the time necessary to regain their driving ability. This result indicates that many people who drink before driving will have difficulty following the advertisement’s advice. Which of the following, if true, most strongly supports the argument above?

Options :

A :

Many people, if they plan to drink alcohol, make arrangements beforehand for a nondrinker to drive them

home.

B :

The subjects in the hospital study generally rated their abilities more conservatively than would people

drinking alcohol outside a hospital setting.

C :

Some people refrain from drinking if they will have to drive to get home afterward.

D :

The subjects in the hospital study were also questioned about the time necessary to regain abilities that do

not play an important role in driving safely.

E :

Awareness of the public-service advertisement is higher among the general population than it was among

the subjects in the hospital study.

Answer: B

Question 5

The labor market is changing yet again. Increasingly, American business is turning to interim staffing to cover a greater number of its employment vacancies. Once interim (or temporary) staffing was reserved for the lowerlevel positions requiring little training, such as an envelope stuffer, receptionist, day laborer, and the like. Today, however, a more highly trained professional is being sought for interim work. It is not uncommon to find computer programmers, writers, marketing professionals, CPAs, and even chief financial officers working in an interim capacity. The reasons for these changes in staffing norms are generated at both the employer and employee level. Employers are pushing the drive toward interim staffing in order to maintain maximum flexibility. Companies can be more innovative and flexible in their planning cycles if they have the option to hire employees on an as-needed basis. Additionally, employers save money using interim staffers, as they are not required to provide health insurance to temporary workers and they are not obligated to pay severance when the job terminates. Employees, too, are pushing the trend toward interim staffing. Increasingly, professionals are seeking more flexibility in their work schedules – often in response to family obligations. No longer does the permanent 9 to 5, Monday through Friday schedule work for everyone. By working interim, employees can work when it fits their schedules. However, interim staffing is not for everyone. Organizations whose workflow requires continuity of personnel may find interim staffing an impediment to productivity. Likewise, employees who need a steady source of income or who require the health insurance and other benefits provided by permanent employers may find the unpredictability in interim work problematic. Given the author’s purpose, which of the following would most enhance this passage?

Options :

A : an interview with an interim employee

B : statistics illustrating the increased emphasis on interim staffing

C : a discussion of whether interim employees deserve benefits

D : examples of positions that are not good for interim employees

E : statistics illustrating how much a company can save by using interim employees
