Although custom prosthetic bone replacements produced through a new computer-aided design process will cost more than twice as much as
ordinary replacements, custom replacements should still be cost-effective
. Not only will surgery and recovery time be reduced
, but custom replacements should last longer
, thereby reducing
the need for further hospital stays.Question Stem
Which of the following must be studied in order to evaluate the argument presented above?
Evaluate Question - Which option validates or invalidates the conclusion abovePre-thinking
Custom replacements may last more than twice the amount of time than ordinary replacements
Custom replacements may last less than twice the amount of time than ordinary replacementsAnswer Choices
A. The amount of time a patient spends in surgery versus the amount of time spent recovering from surgeryINCORRECT ANSWER - Comparing the time spent in surgery and time spent recovering is not going to help us evaluate this argument
B. The amount by which the cost of producing custom replacements has declined with the introduction of the new technique for producing themINCORRECT ANSWER - We are not told how much will the cost decrease?
C. The degree to which the use of custom replacements is likely to reduce the need for repeat surgery when compared with the use of ordinary replacementsCORRECT ANSWER - If the custom replacements last longer then they will definitely be cost effective. So this helps us know if these replacements are cost effective
D. The degree to which custom replacements produced with the new technique are more carefully manufactured than are ordinary replacementsINCORRECT ANSWER - carefully manufactured is not important. The quality of the product is not in question here
E. The amount by which custom replacements produced with the new technique will drop in cost as the production procedures become standardized and applicable on a larger scaleINCORRECT ANSWER - Future reduction in the cost is not relevant.
