Although the new cochleae manufactured by Medotech will cost more than twice as much as the cochlear implants now in use, Medotech implants should still be cost-effective. Not only will surgery and recovery time be reduced, but Medotech cochlear replacements should last longer, thereby reducing the need for further hospital stays.

Q:Which of the following must be studied in order to evaluate the argument presented above?

• The amount of time a patient spends in surgery versus the amount of time spent recovering from surgery.
  
  
  A
• The amount by which the cost of producing Medotech cochlear replacements has declined with the introduction of the new technique for producing them B
• The degree to which the use of Medotech cochlear replacements is likely to reduce the need for repeat surgery when compared with the use of the replacements now in use. C
• The degree to which the use of Medotech replacements are more carefully manufactured than are the replacements now in use D

• More blackouts occur between midnight and eight o'clock in the morning than at any other time B
• Over the course of a year, the company's computers will require periodical checks and upkeep C
• Mental alertness is lower in the late night than during the day, especially in people not accustomed to working at night D

The tanneries claim that chemical waste dumps pose no threat to people living near them. If this is true, then why do they locate the plants in sparsely populated regions? By not locating the chemical dumps in densely populated areas the tanneries tacitly admits that these chemicals are potentially dangerous to the people living nearby.

Q:Which of the following, if true, would most weaken the author's argument?

• Funding through the environmental Super Fund to clean up poorly run waste dumps is reserved for rural areas only A
• Until chemical dumps are proven 100% safe, it would be imprudent to locate them were they could potentially do the most harm. B
• Locating the dumps in sparsely populated areas is less expensive and involves less government red tape C
• The potential for chemicals to leach into the water table has in the past been underestimated D
• People in cities are more likely to site the industry if their health is harmed by the drumps E

A poster in an eye clinic advises people, who have received eye drops X that blur vision, refrain from driving until they can do so safely. In a Gov't initiated hospital study, however, subjects questioned immediately after they received such drops and underestimated the time necessary to regain their driving ability. This result indicates that many people with eye drops X will be unlikely to follow the advice.

Q:Which of the following, if true, most strongly supports the argument above?

• Many people, if they know they will receive eye drops X, make arrangements beforehand for a friend or relative to drive them home A
• The subjects in the hospital study generally rated their abilities more conservatively than they would if they were outside the framework of a scientific experiment B
• Some people ask their doctors not to give them eye drops X that blur vision if they will have to drive to get home afterward C
• The subjects in the study were also questioned about the time necessary to regain abilities that do not play an important role in driving safely D
